NAME

       hg - Mercurial source code management system

SYNOPSIS

       hg command [option]... [argument]...

DESCRIPTION

       The hg command provides a command line interface to the Mercurial system.

COMMAND ELEMENTS

       files...
              indicates  one or more filename or relative path filenames; see File Name Patterns for information
              on pattern matching

       path   indicates a path on the local machine

       revision
              indicates a changeset which can be specified as a changeset revision number, a tag,  or  a  unique
              substring of the changeset hash value

       repository path
              either the pathname of a local repository or the URI of a remote repository.

OPTIONS

COMMANDS

   add
       hg add [OPTION]... [FILE]...

       Schedule files to be version controlled and added to the repository.

       The files will be added to the repository at the next commit. To undo an add before that, see hg forget.

       If no names are given, add all files to the repository.

       An example showing how new (unknown) files are added automatically by hg add:

       $ ls
       foo.c
       $ hg status
       ? foo.c
       $ hg add
       adding foo.c
       $ hg status
       A foo.c

       Returns 0 if all files are successfully added.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -S, --subrepos
              recurse into subrepositories

       -n, --dry-run
              do not perform actions, just print output

   addremove
       hg addremove [OPTION]... [FILE]...

       Add all new files and remove all missing files from the repository.

       New  files  are  ignored  if they match any of the patterns in .hgignore. As with add, these changes take
       effect at the next commit.

       Use the -s/--similarity option to detect  renamed  files.  This  option  takes  a  percentage  between  0
       (disabled)  and  100  (files  must  be identical) as its parameter. With a parameter greater than 0, this
       compares every removed file with every added file and records those similar enough as renames.  Detecting
       renamed files this way can be expensive. After using this option, hg status -C can be used to check which
       files  were  identified  as  moved or renamed. If not specified, -s/--similarity defaults to 100 and only
       renames of identical files are detected.

       Returns 0 if all files are successfully added.

       Options:

       -s, --similarity
              guess renamed files by similarity (0<=s<=100)

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -n, --dry-run
              do not perform actions, just print output

   annotate
       hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...

       List changes in files, showing the revision id responsible for each line

       This command is useful for discovering when a change was made and by whom.

       Without the -a/--text option, annotate will avoid  processing  files  it  detects  as  binary.  With  -a,
       annotate  will  annotate  the  file  anyway,  although  the  results  will probably be neither useful nor
       desirable.

       Returns 0 on success.

       Options:

       -r, --rev
              annotate the specified revision

       --follow
              follow copies/renames and list the filename (DEPRECATED)

       --no-follow
              don't follow copies and renames

       -a, --text
              treat all files as text

       -u, --user
              list the author (long with -v)

       -f, --file
              list the filename

       -d, --date
              list the date (short with -q)

       -n, --number
              list the revision number (default)

       -c, --changeset
              list the changeset

       -l, --line-number
              show line number at the first appearance

       -w, --ignore-all-space
              ignore white space when comparing lines

       -b, --ignore-space-change
              ignore changes in the amount of white space

       -B, --ignore-blank-lines
              ignore changes whose lines are all blank

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

              aliases: blame

   archive
       hg archive [OPTION]... DEST

       By default, the revision used is the parent of the working directory; use -r/--rev to specify a different
       revision.

       The archive type is automatically detected based on file extension (or override using -t/--type).

       Examples:

       • create a zip file containing the 1.0 release:

         hg archive -r 1.0 project-1.0.zip

       • create a tarball excluding .hg files:

         hg archive project.tar.gz -X ".hg*"

       Valid types are:

       files

              a directory full of files (default)

       tar

              tar archive, uncompressed

       tbz2

              tar archive, compressed using bzip2

       tgz

              tar archive, compressed using gzip

       uzip

              zip archive, uncompressed

       zip

              zip archive, compressed using deflate

       The exact name of the destination archive or directory is given using a format string; see hg help export
       for details.

       Each member added to an archive file has a directory prefix  prepended.  Use  -p/--prefix  to  specify  a
       format string for the prefix. The default is the basename of the archive, with suffixes removed.

       Returns 0 on success.

       Options:

       --no-decode
              do not pass files through decoders

       -p, --prefix
              directory prefix for files in archive

       -r, --rev
              revision to distribute

       -t, --type
              type of distribution to create

       -S, --subrepos
              recurse into subrepositories

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   backout
       hg backout [OPTION]... [-r] REV

       Prepare a new changeset with the effect of REV undone in the current working directory.

       If  REV  is  the  parent  of  the  working directory, then this new changeset is committed automatically.
       Otherwise, hg needs to merge the changes and the merged result is left uncommitted.

       Note   backout cannot be used to fix either an unwanted or incorrect merge.

       By default, the pending changeset will have one parent, maintaining a linear history. With  --merge,  the
       pending  changeset will instead have two parents: the old parent of the working directory and a new child
       of REV that simply undoes REV.

       Before version 1.7, the behavior without --merge was equivalent to  specifying  --merge  followed  by  hg
       update --clean . to cancel the merge and leave the child of REV as a head to be merged separately.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success.

       Options:

       --merge
              merge with old dirstate parent after backout

       --parent
              parent to choose when backing out merge (DEPRECATED)

       -r, --rev
              revision to backout

       -t, --tool
              specify merge tool

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

   bisect
       hg bisect [-gbsr] [-U] [-c CMD] [REV]

       This  command  helps to find changesets which introduce problems. To use, mark the earliest changeset you
       know exhibits the problem as bad, then mark the latest changeset which is free from the problem as  good.
       Bisect  will  update your working directory to a revision for testing (unless the -U/--noupdate option is
       specified). Once you have performed tests, mark the working directory as good or  bad,  and  bisect  will
       either update to another candidate changeset or announce that it has found the bad revision.

       As  a shortcut, you can also use the revision argument to mark a revision as good or bad without checking
       it out first.

       If you supply a command, it will be used for automatic bisection.  The environment variable HG_NODE  will
       contain  the  ID  of  the  changeset  being  tested.  The exit status of the command will be used to mark
       revisions as good or bad: status 0 means good, 125 means to skip the revision, 127  (command  not  found)
       will abort the bisection, and any other non-zero exit status means the revision is bad.

       Some examples:

       • start a bisection with known bad revision 34, and good revision 12:

         hg bisect --bad 34
         hg bisect --good 12

       • advance the current bisection by marking current revision as good or bad:

         hg bisect --good
         hg bisect --bad

       • mark  the  current  revision,  or  a known revision, to be skipped (e.g. if that revision is not usable
         because of another issue):

         hg bisect --skip
         hg bisect --skip 23

       • skip all revisions that do not touch directories foo or bar:

         hg bisect --skip "!( file('path:foo') & file('path:bar') )"

       • forget the current bisection:

         hg bisect --reset

       • use 'make && make tests' to automatically find the first broken revision:

         hg bisect --reset
         hg bisect --bad 34
         hg bisect --good 12
         hg bisect --command "make && make tests"

       • see all changesets whose states are already known in the current bisection:

         hg log -r "bisect(pruned)"

       • see the changeset currently being bisected (especially useful if running with -U/--noupdate):

         hg log -r "bisect(current)"

       • see all changesets that took part in the current bisection:

         hg log -r "bisect(range)"

       • you can even get a nice graph:

         hg log --graph -r "bisect(range)"

       See hg help revsets for more about the bisect() keyword.

       Returns 0 on success.

       Options:

       -r, --reset
              reset bisect state

       -g, --good
              mark changeset good

       -b, --bad
              mark changeset bad

       -s, --skip
              skip testing changeset

       -e, --extend
              extend the bisect range

       -c, --command
              use command to check changeset state

       -U, --noupdate
              do not update to target

   bookmarks
       hg bookmarks [OPTIONS]... [NAME]...

       Bookmarks are pointers to certain commits that move when committing.  Bookmarks are local.  They  can  be
       renamed,  copied  and deleted. It is possible to use hg merge NAME to merge from a given bookmark, and hg
       update NAME to update to a given bookmark.

       You can use hg bookmark NAME to set a bookmark on the working directory's parent revision with the  given
       name.  If  you  specify  a revision using -r REV (where REV may be an existing bookmark), the bookmark is
       assigned to that revision.

       Bookmarks can be pushed and pulled between repositories  (see  hg  help  push and  hg  help  pull).  This
       requires  both  the  local  and remote repositories to support bookmarks. For versions prior to 1.8, this
       means the bookmarks extension must be enabled.

       If you set a bookmark called '@', new clones of the repository will have that revision checked  out  (and
       the bookmark made active) by default.

       With  -i/--inactive, the new bookmark will not be made the active bookmark. If -r/--rev is given, the new
       bookmark will not be made active even if -i/--inactive is not given. If no NAME  is  given,  the  current
       active bookmark will be marked inactive.

       Options:

       -f, --force
              force

       -r, --rev
              revision

       -d, --delete
              delete a given bookmark

       -m, --rename
              rename a given bookmark

       -i, --inactive
              mark a bookmark inactive

              aliases: bookmark

   branch
       hg branch [-fC] [NAME]

       Note   Branch  names are permanent and global. Use hg bookmark to create a light-weight bookmark instead.
              See hg help glossary for more information about named branches and bookmarks.

       With no argument, show the current branch name. With one argument, set the working directory branch  name
       (the  branch  will  not exist in the repository until the next commit). Standard practice recommends that
       primary development take place on the 'default' branch.

       Unless -f/--force is specified, branch will not let you set a branch name that already  exists,  even  if
       it's inactive.

       Use  -C/--clean  to  reset  the  working directory branch to that of the parent of the working directory,
       negating a previous branch change.

       Use the command hg update to switch to an existing branch. Use  hg  commit  --close-branch to  mark  this
       branch as closed.

       Returns 0 on success.

       Options:

       -f, --force
              set branch name even if it shadows an existing branch

       -C, --clean
              reset branch name to parent branch name

   branches
       hg branches [-ac]

       List  the  repository's  named branches, indicating which ones are inactive. If -c/--closed is specified,
       also list branches which have been marked closed (see hg commit --close-branch).

       If -a/--active is specified, only show active branches. A branch is  considered  active  if  it  contains
       repository heads.

       Use the command hg update to switch to an existing branch.

       Returns 0.

       Options:

       -a, --active
              show only branches that have unmerged heads

       -c, --closed
              show normal and closed branches

   bundle
       hg bundle [-f] [-t TYPE] [-a] [-r REV]... [--base REV]... FILE [DEST]

       Generate a compressed changegroup file collecting changesets not known to be in another repository.

       If  you  omit  the  destination  repository,  then hg assumes the destination will have all the nodes you
       specify with --base parameters. To create a bundle containing all changesets,  use  -a/--all  (or  --base
       null).

       You  can  change  compression  method  with the -t/--type option.  The available compression methods are:
       none, bzip2, and gzip (by default, bundles are compressed using bzip2).

       The bundle file can then be transferred using conventional means and applied to another  repository  with
       the  unbundle  or  pull  command.  This  is  useful  when  direct push and pull are not available or when
       exporting an entire repository is undesirable.

       Applying bundles preserves all changeset contents including  permissions,  copy/rename  information,  and
       revision history.

       Returns 0 on success, 1 if no changes found.

       Options:

       -f, --force
              run even when the destination is unrelated

       -r, --rev
              a changeset intended to be added to the destination

       -b, --branch
              a specific branch you would like to bundle

       --base a base changeset assumed to be available at the destination

       -a, --all
              bundle all changesets in the repository

       -t, --type
              bundle compression type to use (default: bzip2)

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

   cat
       hg cat [OPTION]... FILE...

       Print  the specified files as they were at the given revision. If no revision is given, the parent of the
       working directory is used.

       Output may be to a file, in which case the name  of  the  file  is  given  using  a  format  string.  The
       formatting rules are the same as for the export command, with the following additions:

       %s

              basename of file being printed

       %d

              dirname of file being printed, or '.' if in repository root

       %p

              root-relative path name of file being printed

       Returns 0 on success.

       Options:

       -o, --output
              print output to file with formatted name

       -r, --rev
              print the given revision

       --decode
              apply any matching decode filter

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   clone
       hg clone [OPTION]... SOURCE [DEST]

       Create a copy of an existing repository in a new directory.

       If no destination directory name is specified, it defaults to the basename of the source.

       The  location of the source is added to the new repository's .hg/hgrc file, as the default to be used for
       future pulls.

       Only local paths and ssh:// URLs are supported as  destinations.  For  ssh://  destinations,  no  working
       directory or .hg/hgrc will be created on the remote side.

       To  pull only a subset of changesets, specify one or more revisions identifiers with -r/--rev or branches
       with -b/--branch. The resulting clone will contain only the specified  changesets  and  their  ancestors.
       These  options  (or  'clone  src#rev  dest')  imply --pull, even for local source repositories. Note that
       specifying a tag will include the tagged changeset but not the changeset containing the tag.

       If the source repository has a bookmark called '@' set, that revision will be  checked  out  in  the  new
       repository by default.

       To  check  out  a particular version, use -u/--update, or -U/--noupdate to create a clone with no working
       directory.

       For efficiency, hardlinks are used for cloning whenever the  source  and  destination  are  on  the  same
       filesystem  (note  this  applies  only  to  the  repository  data,  not  to  the working directory). Some
       filesystems, such as AFS, implement hardlinking incorrectly, but do not report errors.  In  these  cases,
       use the --pull option to avoid hardlinking.

       In some cases, you can clone repositories and the working directory using full hardlinks with

       $ cp -al REPO REPOCLONE

       This  is  the  fastest  way to clone, but it is not always safe. The operation is not atomic (making sure
       REPO is not modified during the operation is up to you) and you have to  make  sure  your  editor  breaks
       hardlinks (Emacs and most Linux Kernel tools do so). Also, this is not compatible with certain extensions
       that place their metadata under the .hg directory, such as mq.

       Mercurial will update the working directory to the first applicable revision from this list:

       a. null if -U or the source repository has no changesets

       b. if  -u  .  and  the  source  repository  is local, the first parent of the source repository's working
          directory

       c. the changeset specified with -u (if a branch name, this means the latest head of that branch)

       d. the changeset specified with -r

       e. the tipmost head specified with -b

       f. the tipmost head specified with the url#branch source syntax

       g. the revision marked with the '@' bookmark, if present

       h. the tipmost head of the default branch

       i. tip

       Examples:

       • clone a remote repository to a new directory named hg/:

         hg clone http://selenic.com/hg

       • create a lightweight local clone:

         hg clone project/ project-feature/

       • clone from an absolute path on an ssh server (note double-slash):

         hg clone ssh://user@server//home/projects/alpha/

       • do a high-speed clone over a LAN while checking out a specified version:

         hg clone --uncompressed http://server/repo -u 1.5

       • create a repository without changesets after a particular revision:

         hg clone -r 04e544 experimental/ good/

       • clone (and track) a particular named branch:

         hg clone http://selenic.com/hg#stable

       See hg help urls for details on specifying URLs.

       Returns 0 on success.

       Options:

       -U, --noupdate
              the clone will include an empty working copy (only a repository)

       -u, --updaterev
              revision, tag or branch to check out

       -r, --rev
              include the specified changeset

       -b, --branch
              clone only the specified branch

       --pull use pull protocol to copy metadata

       --uncompressed
              use uncompressed transfer (fast over LAN)

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

   commit
       hg commit [OPTION]... [FILE]...

       Commit changes to the given files into the repository. Unlike a centralized  SCM,  this  operation  is  a
       local operation. See hg push for a way to actively distribute your changes.

       If a list of files is omitted, all changes reported by hg status will be committed.

       If you are committing the result of a merge, do not provide any filenames or -I/-X filters.

       If no commit message is specified, Mercurial starts your configured editor where you can enter a message.
       In case your commit fails, you will find a backup of your message in .hg/last-message.txt.

       The --amend flag can be used to amend the parent of the working directory with a new commit that contains
       the changes in the parent in addition to those currently reported by hg status, if there are any. The old
       commit  is  stored in a backup bundle in .hg/strip-backup (see hg help bundle and hg help unbundle on how
       to restore it).

       Message, user and date are taken from the amended commit unless specified. When a message isn't specified
       on the command line, the editor will open with the message of the amended commit.

       It is not possible to amend public changesets (see hg help phases) or changesets that have children.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success, 1 if nothing changed.

       Options:

       -A, --addremove
              mark new/missing files as added/removed before committing

       --close-branch
              mark a branch as closed, hiding it from the branch list

       --amend
              amend the parent of the working dir

       -s, --secret
              use the secret phase for committing

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

       -S, --subrepos
              recurse into subrepositories

              aliases: ci

   copy
       hg copy [OPTION]... [SOURCE]... DEST

       Mark dest as having copies of source files. If dest is a directory, copies are put in that directory.  If
       dest is a file, the source must be a single file.

       By  default, this command copies the contents of files as they exist in the working directory. If invoked
       with -A/--after, the operation is recorded, but no copying is performed.

       This command takes effect with the next commit. To undo a copy before that, see hg revert.

       Returns 0 on success, 1 if errors are encountered.

       Options:

       -A, --after
              record a copy that has already occurred

       -f, --force
              forcibly copy over an existing managed file

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -n, --dry-run
              do not perform actions, just print output

              aliases: cp

   diff
       hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...

       Show differences between revisions for the specified files.

       Differences between files are shown using the unified diff format.

       Note   diff may generate unexpected results for merges, as it  will  default  to  comparing  against  the
              working directory's first parent changeset if no revisions are specified.

       When  two  revision  arguments  are  given,  then  changes are shown between those revisions. If only one
       revision is specified then that revision is compared to the working directory, and, when no revisions are
       specified, the working directory files are compared to its parent.

       Alternatively you can specify -c/--change with a revision to see the changes in that  changeset  relative
       to its first parent.

       Without  the  -a/--text  option, diff will avoid generating diffs of files it detects as binary. With -a,
       diff will generate a diff anyway, probably with undesirable results.

       Use the -g/--git option to generate diffs in the git extended diff format. For more information, read  hg
       help diffs.

       Examples:

       • compare a file in the current working directory to its parent:

         hg diff foo.c

       • compare two historical versions of a directory, with rename info:

         hg diff --git -r 1.0:1.2 lib/

       • get change stats relative to the last change on some date:

         hg diff --stat -r "date('may 2')"

       • diff all newly-added files that contain a keyword:

         hg diff "set:added() and grep(GNU)"

       • compare a revision and its parents:

         hg diff -c 9353         # compare against first parent
         hg diff -r 9353^:9353   # same using revset syntax
         hg diff -r 9353^2:9353  # compare against the second parent

       Returns 0 on success.

       Options:

       -r, --rev
              revision

       -c, --change
              change made by revision

       -a, --text
              treat all files as text

       -g, --git
              use git extended diff format

       --nodates
              omit dates from diff headers

       -p, --show-function
              show which function each change is in

       --reverse
              produce a diff that undoes the changes

       -w, --ignore-all-space
              ignore white space when comparing lines

       -b, --ignore-space-change
              ignore changes in the amount of white space

       -B, --ignore-blank-lines
              ignore changes whose lines are all blank

       -U, --unified
              number of lines of context to show

       --stat output diffstat-style summary of changes

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -S, --subrepos
              recurse into subrepositories

   export
       hg export [OPTION]... [-o OUTFILESPEC] [-r] [REV]...

       Print  the  changeset header and diffs for one or more revisions.  If no revision is given, the parent of
       the working directory is used.

       The information shown in the changeset header is: author, date, branch name (if  non-default),  changeset
       hash, parent(s) and commit comment.

       Note   export  may  generate  unexpected  diff  output for merge changesets, as it will compare the merge
              changeset against its first parent only.

       Output may be to a file, in which case the name  of  the  file  is  given  using  a  format  string.  The
       formatting rules are as follows:

       %%

              literal "%" character

       %H

              changeset hash (40 hexadecimal digits)

       %N

              number of patches being generated

       %R

              changeset revision number

       %b

              basename of the exporting repository

       %h

              short-form changeset hash (12 hexadecimal digits)

       %m

              first line of the commit message (only alphanumeric characters)

       %n

              zero-padded sequence number, starting at 1

       %r

              zero-padded changeset revision number

       Without  the -a/--text option, export will avoid generating diffs of files it detects as binary. With -a,
       export will generate a diff anyway, probably with undesirable results.

       Use the -g/--git option to generate diffs in the git extended diff format. See  hg  help  diffs for  more
       information.

       With the --switch-parent option, the diff will be against the second parent. It can be useful to review a
       merge.

       Examples:

       • use export and import to transplant a bugfix to the current branch:

         hg export -r 9353 | hg import -

       • export all the changesets between two revisions to a file with rename information:

         hg export --git -r 123:150 > changes.txt

       • split outgoing changes into a series of patches with descriptive names:

         hg export -r "outgoing()" -o "%n-%m.patch"

       Returns 0 on success.

       Options:

       -o, --output
              print output to file with formatted name

       --switch-parent
              diff against the second parent

       -r, --rev
              revisions to export

       -a, --text
              treat all files as text

       -g, --git
              use git extended diff format

       --nodates
              omit dates from diff headers

   forget
       hg forget [OPTION]... FILE...

       Mark the specified files so they will no longer be tracked after the next commit.

       This  only  removes  files  from the current branch, not from the entire project history, and it does not
       delete them from the working directory.

       To undo a forget before the next commit, see hg add.

       Examples:

       • forget newly-added binary files:

         hg forget "set:added() and binary()"

       • forget files that would be excluded by .hgignore:

         hg forget "set:hgignore()"

       Returns 0 on success.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   graft
       hg graft [OPTION]... [-r] REV...

       This command uses Mercurial's merge logic to copy individual changes from other branches without  merging
       branches  in the history graph. This is sometimes known as 'backporting' or 'cherry-picking'. By default,
       graft will copy user, date, and description from the source changesets.

       Changesets that are ancestors of the current revision, that have already been grafted, or that are merges
       will be skipped.

       If --log is specified, log messages will have a comment appended of the form:

       (grafted from CHANGESETHASH)

       If a graft merge results in conflicts, the graft process is interrupted so that the current merge can  be
       manually  resolved.   Once  all  conflicts  are  addressed,  the  graft process can be continued with the
       -c/--continue option.

       Note   The -c/--continue option does not reapply earlier options.

       Examples:

       • copy a single change to the stable branch and edit its description:

         hg update stable
         hg graft --edit 9393

       • graft a range of changesets with one exception, updating dates:

         hg graft -D "2085::2093 and not 2091"

       • continue a graft after resolving conflicts:

         hg graft -c

       • show the source of a grafted changeset:

         hg log --debug -r .

       Returns 0 on successful completion.

       Options:

       -r, --rev
              revisions to graft

       -c, --continue
              resume interrupted graft

       -e, --edit
              invoke editor on commit messages

       --log  append graft info to log message

       -D, --currentdate
              record the current date as commit date

       -U, --currentuser
              record the current user as committer

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

       -t, --tool
              specify merge tool

       -n, --dry-run
              do not perform actions, just print output

   grep
       hg grep [OPTION]... PATTERN [FILE]...

       Search revisions of files for a regular expression.

       This command behaves differently than Unix  grep.  It  only  accepts  Python/Perl  regexps.  It  searches
       repository  history,  not  the  working  directory. It always prints the revision number in which a match
       appears.

       By default, grep only prints output for the first revision of a file in which it finds a match. To get it
       to print every revision that contains a change in match status ("-" for a match that becomes a non-match,
       or "+" for a non-match that becomes a match), use the --all flag.

       Returns 0 if a match is found, 1 otherwise.

       Options:

       -0, --print0
              end fields with NUL

       --all  print all revisions that match

       -a, --text
              treat all files as text

       -f, --follow
              follow changeset history, or file history across copies and renames

       -i, --ignore-case
              ignore case when matching

       -l, --files-with-matches
              print only filenames and revisions that match

       -n, --line-number
              print matching line numbers

       -r, --rev
              only search files changed within revision range

       -u, --user
              list the author (long with -v)

       -d, --date
              list the date (short with -q)

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   heads
       hg heads [-ct] [-r STARTREV] [REV]...

       With no arguments, show all open branch heads in the repository.  Branch heads are changesets  that  have
       no  descendants  on  the  same branch. They are where development generally takes place and are the usual
       targets for update and merge operations.

       If one or more REVs are given, only open branch heads on  the  branches  associated  with  the  specified
       changesets  are  shown.  This  means  that  you  can  use  hg  heads  . to see the heads on the currently
       checked-out branch.

       If -c/--closed is specified, also show branch heads marked closed (see hg commit --close-branch).

       If STARTREV is specified, only those heads that are descendants of STARTREV will be displayed.

       If -t/--topo is specified, named branch mechanics will be ignored and only topological heads  (changesets
       with no children) will be shown.

       Returns 0 if matching heads are found, 1 if not.

       Options:

       -r, --rev
              show only heads which are descendants of STARTREV

       -t, --topo
              show topological heads only

       -a, --active
              show active branchheads only (DEPRECATED)

       -c, --closed
              show normal and closed branch heads

       --style
              display using template map file

       --template
              display with template

   help
       hg help [-ec] [TOPIC]

       With no arguments, print a list of commands with short help messages.

       Given a topic, extension, or command name, print help for that topic.

       Returns 0 if successful.

       Options:

       -e, --extension
              show only help for extensions

       -c, --command
              show only help for commands

       -k, --keyword
              show topics matching keyword

   identify
       hg identify [-nibtB] [-r REV] [SOURCE]

       Print  a  summary  identifying  the  repository  state  at  REV using one or two parent hash identifiers,
       followed by a "+" if the working directory has uncommitted changes, the branch name (if not  default),  a
       list of tags, and a list of bookmarks.

       When REV is not given, print a summary of the current state of the repository.

       Specifying  a  path  to  a  repository  root  or  Mercurial  bundle  will cause lookup to operate on that
       repository/bundle.

       Examples:

       • generate a build identifier for the working directory:

         hg id --id > build-id.dat

       • find the revision corresponding to a tag:

         hg id -n -r 1.3

       • check the most recent revision of a remote repository:

         hg id -r tip http://selenic.com/hg/

       Returns 0 if successful.

       Options:

       -r, --rev
              identify the specified revision

       -n, --num
              show local revision number

       -i, --id
              show global revision id

       -b, --branch
              show branch

       -t, --tags
              show tags

       -B, --bookmarks
              show bookmarks

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

              aliases: id

   import
       hg import [OPTION]... PATCH...

       Import a list of patches and commit them individually (unless --no-commit is specified).

       Because import first applies changes to the working directory, import will abort if there are outstanding
       changes.

       You can import a patch straight from a mail message. Even patches as attachments work (to  use  the  body
       part,  it  must have type text/plain or text/x-patch). From and Subject headers of email message are used
       as default committer and commit message. All text/plain body parts before first diff are added to  commit
       message.

       If  the  imported  patch was generated by hg export, user and description from patch override values from
       message headers and body. Values given on command line with -m/--message and -u/--user override these.

       If --exact is specified, import will set the working  directory  to  the  parent  of  each  patch  before
       applying  it,  and  will abort if the resulting changeset has a different ID than the one recorded in the
       patch. This may happen due to character set problems or other deficiencies in the text patch format.

       Use --bypass to apply and commit patches directly to the repository, not touching the working  directory.
       Without --exact, patches will be applied on top of the working directory parent revision.

       With  -s/--similarity,  hg will attempt to discover renames and copies in the patch in the same way as hg
       addremove.

       To read a patch from standard input, use "-" as the patch name. If a URL is specified, the patch will  be
       downloaded from it.  See hg help dates for a list of formats valid for -d/--date.

       Examples:

       • import a traditional patch from a website and detect renames:

         hg import -s 80 http://example.com/bugfix.patch

       • import a changeset from an hgweb server:

         hg import http://www.selenic.com/hg/rev/5ca8c111e9aa

       • import all the patches in an Unix-style mbox:

         hg import incoming-patches.mbox

       • attempt to exactly restore an exported changeset (not always possible):

         hg import --exact proposed-fix.patch

       Returns 0 on success.

       Options:

       -p, --strip
              directory  strip  option  for  patch.  This has the same meaning as the corresponding patch option
              (default: 1)

       -b, --base
              base path (DEPRECATED)

       -e, --edit
              invoke editor on commit messages

       -f, --force
              skip check for outstanding uncommitted changes (DEPRECATED)

       --no-commit

   incoming
       hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]

       Show new changesets found in the  specified  path/URL  or  the  default  pull  location.  These  are  the
       changesets that would have been pulled if a pull at the time you issued this command.

       For remote repository, using --bundle avoids downloading the changesets twice if the incoming is followed
       by a pull.

       See pull for valid source format details.

       Returns 0 if there are incoming changes, 1 otherwise.

       Options:

       -f, --force
              run even if remote repository is unrelated

       -n, --newest-first
              show newest record first

       --bundle
              file to store the bundles into

       -r, --rev

       -l, --limit
              limit number of changes displayed

       -M, --no-merges
              do not show merges

       --stat output diffstat-style summary of changes

       -G, --graph
              show the revision DAG

       --style
              display using template map file

       --template
              display with template

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

       -S, --subrepos
              recurse into subrepositories

              aliases: in

   init
       hg init [-e CMD] [--remotecmd CMD] [DEST]

       Initialize  a  new  repository  in the given directory. If the given directory does not exist, it will be
       created.

       If no directory is given, the current directory is used.

       It is possible to specify an ssh:// URL as the destination.  See hg help urls for more information.

       Returns 0 on success.

       Options:

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

   locate
       hg locate [OPTION]... [PATTERN]...

       Print files under Mercurial control in the working directory whose names match the given patterns.

       By default, this command searches all directories in the working directory. To search  just  the  current
       directory and its subdirectories, use "--include .".

       If  no patterns are given to match, this command prints the names of all files under Mercurial control in
       the working directory.

       If you want to feed the output of this command into the "xargs" command, use the -0 option to  both  this
       command  and  "xargs".  This  will  avoid  the  problem of "xargs" treating single filenames that contain
       whitespace as multiple filenames.

       Returns 0 if a match is found, 1 otherwise.

       Options:

       -r, --rev
              search the repository as it is in REV

       -0, --print0
              end filenames with NUL, for use with xargs

       -f, --fullpath
              print complete paths from the filesystem root

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   log
       hg log [OPTION]... [FILE]

       Print the revision history of the specified files or the entire project.

       If no revision range is specified, the default is tip:0 unless --follow is set, in which case the working
       directory parent is used as the starting revision.

       File history is shown without following rename or copy history of files. Use -f/--follow with a  filename
       to  follow  history  across  renames  and copies. --follow without a filename will only show ancestors or
       descendants of the starting revision.

       By default this command prints revision number and changeset id, tags, non-trivial  parents,  user,  date
       and  time, and a summary for each commit. When the -v/--verbose switch is used, the list of changed files
       and full commit message are shown.

       Note   log -p/--patch may generate unexpected diff output for merge changesets, as it will  only  compare
              the  merge  changeset  against its first parent. Also, only files different from BOTH parents will
              appear in files:.

       Note   for performance reasons, log FILE may omit duplicate changes made on branches and  will  not  show
              deletions. To see all changes including duplicates and deletions, use the --removed switch.

       Some examples:

       • changesets with full descriptions and file lists:

         hg log -v

       • changesets ancestral to the working directory:

         hg log -f

       • last 10 commits on the current branch:

         hg log -l 10 -b .

       • changesets showing all modifications of a file, including removals:

         hg log --removed file.c

       • all changesets that touch a directory, with diffs, excluding merges:

         hg log -Mp lib/

       • all revision numbers that match a keyword:

         hg log -k bug --template "{rev}\n"

       • check if a given changeset is included is a tagged release:

         hg log -r "a21ccf and ancestor(1.9)"

       • find all changesets by some user in a date range:

         hg log -k alice -d "may 2008 to jul 2008"

       • summary of all changesets after the last tag:

         hg log -r "last(tagged())::" --template "{desc|firstline}\n"

       See hg help dates for a list of formats valid for -d/--date.

       See hg help revisions and hg help revsets for more about specifying revisions.

       See hg help templates for more about pre-packaged styles and specifying custom templates.

       Returns 0 on success.

       Options:

       -f, --follow
              follow changeset history, or file history across copies and renames

              aliases: history

   manifest
       hg manifest [-r REV]

       Print  a  list  of  version  controlled files for the given revision.  If no revision is given, the first
       parent of the working directory is used, or the null revision if no revision is checked out.

       With -v, print file permissions, symlink and executable bits.  With --debug, print file revision hashes.

       If option --all is specified, the list of all files from all revisions is printed. This includes  deleted
       and renamed files.

       Returns 0 on success.

       Options:

       -r, --rev
              revision to display

       --all  list files from all revisions

   merge
       hg merge [-P] [-f] [[-r] REV]

       The  current  working directory is updated with all changes made in the requested revision since the last
       common predecessor revision.

       Files that changed between either parent are marked as changed for the next commit and a commit  must  be
       performed  before  any  further  updates  to  the  repository  are allowed. The next commit will have two
       parents.

       --tool can be used to specify the merge tool used for file merges. It overrides the  HGMERGE  environment
       variable and your configuration files. See hg help merge-tools for options.

       If  no  revision  is specified, the working directory's parent is a head revision, and the current branch
       contains exactly one other head, the other head  is  merged  with  by  default.  Otherwise,  an  explicit
       revision with which to merge with must be provided.

       hg resolve must be used to resolve unresolved files.

       To  undo  an uncommitted merge, use hg update --clean . which will check out a clean copy of the original
       merge parent, losing all changes.

       Returns 0 on success, 1 if there are unresolved files.

       Options:

       -f, --force
              force a merge including outstanding changes (DEPRECATED)

       -r, --rev
              revision to merge

       -P, --preview
              review revisions to merge (no merge is performed)

       -t, --tool
              specify merge tool

   outgoing
       hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]

       Show changesets not found in the specified destination repository or the default push location. These are
       the changesets that would be pushed if a push was requested.

       See pull for details of valid destination formats.

       Returns 0 if there are outgoing changes, 1 otherwise.

       Options:

       -f, --force
              run even when the destination is unrelated

       -r, --rev
              a changeset intended to be included in the destination

       -n, --newest-first
              show newest record first

              recurse into subrepositories

              aliases: out

   parents
       hg parents [-r REV] [FILE]

       Print the working directory's parent revisions. If a revision is given via -r/--rev, the parent  of  that
       revision  will  be printed.  If a file argument is given, the revision in which the file was last changed
       (before the working directory revision or the argument to --rev if given) is printed.

       Returns 0 on success.

       Options:

       -r, --rev
              show parents of the specified revision

       --style
              display using template map file

       --template
              display with template

   paths
       hg paths [NAME]

       Show definition of symbolic path name NAME. If no name is given, show definition of all available names.

       Option -q/--quiet suppresses all output when searching for NAME  and  shows  only  the  path  names  when
       listing all definitions.

       Path  names  are defined in the [paths] section of your configuration file and in /etc/mercurial/hgrc. If
       run inside a repository, .hg/hgrc is used, too.

       The path names default and default-push  have  a  special  meaning.   When  performing  a  push  or  pull
       operation, they are used as fallbacks if no location is specified on the command-line.  When default-push
       is  set,  it  will  be  used for push and default will be used for pull; otherwise default is used as the
       fallback for both.  When cloning a repository, the clone source is written as default in .hg/hgrc.   Note
       that default and default-push apply to all inbound (e.g.  hg incoming) and outbound (e.g. hg outgoing, hg
       email and hg bundle) operations.

       See hg help urls for more information.

       Returns 0 on success.

   phase
       hg phase [-p|-d|-s] [-f] [-r] REV...

       With no argument, show the phase name of specified revisions.

       With one of -p/--public, -d/--draft or -s/--secret, change the phase value of the specified revisions.

       Unless  -f/--force  is  specified,  hg  phase won't move changeset from a lower phase to an higher phase.
       Phases are ordered as follows:

       public < draft < secret

       Return 0 on success, 1 if no phases were changed or some could not be changed.

       Options:

       -p, --public
              set changeset phase to public

       -d, --draft
              set changeset phase to draft

       -s, --secret
              set changeset phase to secret

       -f, --force
              allow to move boundary backward

       -r, --rev
              target revision

   pull
       hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]

       Pull changes from a remote repository to a local one.

       This finds all changes from the repository at the specified  path  or  URL  and  adds  them  to  a  local
       repository  (the  current  one  unless -R is specified). By default, this does not update the copy of the
       project in the working directory.

       Use hg incoming if you want to see what would have been added by a pull  at  the  time  you  issued  this
       command.  If  you then decide to add those changes to the repository, you should use hg pull -r X where X
       is the last changeset listed by hg incoming.

       If SOURCE is omitted, the 'default' path will be used.  See hg help urls for more information.

       Returns 0 on success, 1 if an update had unresolved files.

       Options:

       -u, --update
              update to new branch head if changesets were pulled

       -f, --force
              run even when remote repository is unrelated

       -r, --rev
              a remote changeset intended to be added

       -B, --bookmark
              bookmark to pull

       -b, --branch
              a specific branch you would like to pull

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

   push
       hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]

       Push changesets from the local repository to the specified destination.

       This operation is symmetrical to pull: it is identical to a pull in the destination repository  from  the
       current one.

       By default, push will not allow creation of new heads at the destination, since multiple heads would make
       it unclear which head to use. In this situation, it is recommended to pull and merge before pushing.

       Use  --new-branch  if  you  want  to  allow  push to create a new named branch that is not present at the
       destination. This allows you to only create a new branch without forcing other changes.

       Note   Extra care should be taken with the -f/--force option, which  will  push  all  new  heads  on  all
              branches, an action which will almost always cause confusion for collaborators.

       If  -r/--rev  is  used,  the  specified  revision  and  all  its  ancestors  will be pushed to the remote
       repository.

       If -B/--bookmark is used, the specified bookmarked revision, its ancestors,  and  the  bookmark  will  be
       pushed to the remote repository.

       Please  see  hg  help  urls for important details about ssh:// URLs. If DESTINATION is omitted, a default
       path will be used.

       Returns 0 if push was successful, 1 if nothing to push.

       Options:

       -f, --force
              force push

       -r, --rev
              a changeset intended to be included in the destination

       -B, --bookmark
              bookmark to push

       -b, --branch
              a specific branch you would like to push

       --new-branch
              allow pushing a new branch

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

   recover
       hg recover

       Recover from an interrupted commit or pull.

       This command tries to fix the repository status  after  an  interrupted  operation.  It  should  only  be
       necessary when Mercurial suggests it.

       Returns 0 if successful, 1 if nothing to recover or verify fails.

   remove
       hg remove [OPTION]... FILE...

       Schedule the indicated files for removal from the current branch.

       This  command schedules the files to be removed at the next commit.  To undo a remove before that, see hg
       revert. To undo added files, see hg forget.

       -A/--after can be used to remove only files that have already been deleted, -f/--force  can  be  used  to
       force deletion, and -Af can be used to remove files from the next revision without deleting them from the
       working directory.

       The  following  table  details  the  behavior  of  remove  for different file states (columns) and option
       combinations (rows). The file states are Added [A], Clean [C], Modified [M] and Missing [!]  (as reported
       by hg status). The actions are Warn, Remove (from branch) and Delete (from disk):

       Note that remove never deletes files in Added [A] state from the working directory, not  even  if  option
       --force is specified.

       Returns 0 on success, 1 if any warnings encountered.

       Options:

       -A, --after
              record delete for missing files

              aliases: rm

   rename
       hg rename [OPTION]... SOURCE... DEST

       Mark dest as copies of sources; mark sources for deletion. If dest is a directory, copies are put in that
       directory. If dest is a file, there can only be one source.

       By  default, this command copies the contents of files as they exist in the working directory. If invoked
       with -A/--after, the operation is recorded, but no copying is performed.

       This command takes effect at the next commit. To undo a rename before that, see hg revert.

       Returns 0 on success, 1 if errors are encountered.

       Options:

       -A, --after
              record a rename that has already occurred

       -f, --force
              forcibly copy over an existing managed file

   resolve
       hg resolve [OPTION]... [FILE]...

       Merges with unresolved conflicts are often the result of non-interactive merging using the internal:merge
       configuration setting, or a command-line merge tool like diff3. The resolve command is used to manage the
       files involved in a merge, after hg merge has been run, and before hg commit is  run  (i.e.  the  working
       directory must have two parents). See hg help merge-tools for information on configuring merge tools.

       The resolve command can be used in the following ways:

       • hg  resolve  [--tool  TOOL]  FILE...:  attempt to re-merge the specified files, discarding any previous
         merge attempts. Re-merging is not performed for files already  marked  as  resolved.  Use  --all/-a  to
         select  all unresolved files. --tool can be used to specify the merge tool used for the given files. It
         overrides the HGMERGE environment variable and your configuration files.  Previous  file  contents  are
         saved with a .orig suffix.

       • hg  resolve  -m  [FILE]:  mark  a file as having been resolved (e.g. after having manually fixed-up the
         files). The default is to mark all unresolved files.

       • hg resolve -u [FILE]...: mark a file as unresolved. The default is to mark all resolved files.

       • hg resolve -l: list files which had or still have conflicts.  In the printed list, U = unresolved and R
         = resolved.

       Note that Mercurial will not let you commit files with  unresolved  merge  conflicts.  You  must  use  hg
       resolve -m ... before you can commit after a conflicting merge.

       Returns 0 on success, 1 if any files fail a resolve attempt.

       Options:

       -a, --all
              select all unresolved files

       -l, --list
              list state of files needing merge

       -m, --mark
              mark files as resolved

       -u, --unmark
              mark files as unresolved

       -n, --no-status
              hide status prefix

       -t, --tool
              specify merge tool

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   revert
       hg revert [OPTION]... [-r REV] [NAME]...

       Note   To check out earlier revisions, you should use hg update REV.  To cancel an uncommitted merge (and
              lose your changes), use hg update --clean ..

       With  no  revision  specified,  revert the specified files or directories to the contents they had in the
       parent of the working directory.  This restores  the  contents  of  files  to  an  unmodified  state  and
       unschedules  adds,  removes,  copies,  and  renames.  If  the working directory has two parents, you must
       explicitly specify a revision.

       Using the -r/--rev or -d/--date options, revert the given files or directories to their states  as  of  a
       specific  revision.  Because  revert does not change the working directory parents, this will cause these
       files to appear modified. This can be helpful to "back out" some or all of  an  earlier  change.  See  hg
       backout for a related method.

       Modified  files  are  saved  with  a  .orig  suffix  before  reverting.   To  disable  these backups, use
       --no-backup.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success.

       Options:

       -a, --all
              revert all changes when no arguments given

       -d, --date
              tipmost revision matching date

       -r, --rev
              revert to the specified revision

       -C, --no-backup
              do not save backup copies of files

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -n, --dry-run
              do not perform actions, just print output

   rollback
       hg rollback

       Please use hg commit --amend instead of rollback to correct mistakes in the last commit.

       This command should be used with care. There is only one level of rollback, and there is no way to undo a
       rollback. It will also restore the dirstate at the time of the  last  transaction,  losing  any  dirstate
       changes since that time. This command does not alter the working directory.

       Transactions  are used to encapsulate the effects of all commands that create new changesets or propagate
       existing changesets into a repository.

       For example, the following commands are transactional, and their effects can be rolled back:

       • commit

       • import

       • pull

       • push (with this repository as the destination)

       • unbundle

       To avoid permanent data loss, rollback will refuse to rollback a commit transaction if it  isn't  checked
       out. Use --force to override this protection.

       This  command  is not intended for use on public repositories. Once changes are visible for pull by other
       users, rolling a transaction back locally is ineffective  (someone  else  may  already  have  pulled  the
       changes). Furthermore, a race is possible with readers of the repository; for example an in-progress pull
       from the repository may fail if a rollback is performed.

       Returns 0 on success, 1 if no rollback data is available.

       Options:

       -n, --dry-run
              do not perform actions, just print output

       -f, --force
              ignore safety measures

   root
       hg root

       Print the root directory of the current repository.

       Returns 0 on success.

   serve
       hg serve [OPTION]...

       Start  a  local HTTP repository browser and pull server. You can use this for ad-hoc sharing and browsing
       of repositories. It is recommended to use a real web server to serve a repository for longer  periods  of
       time.

       Please  note that the server does not implement access control.  This means that, by default, anybody can
       read from the server and nobody can write to it by default. Set the web.allow_push option to *  to  allow
       everybody to push to the server. You should use a real web server if you need to authenticate users.

       By  default,  the  server  logs  accesses  to  stdout  and  errors  to stderr. Use the -A/--accesslog and
       -E/--errorlog options to log to files.

       To have the server choose a free port number to listen on, specify a port number of 0; in this case,  the
       server will print the port number it uses.

       Returns 0 on success.

       Options:

       -A, --accesslog
              name of access log file to write to

       -d, --daemon
              run server in background

       --daemon-pipefds
              used internally by daemon mode

       -E, --errorlog
              name of error log file to write to

       -p, --port
              port to listen on (default: 8000)

       -a, --address
              address to listen on (default: all interfaces)

       --prefix
              prefix path to serve from (default: server root)

       -n, --name
              name to show in web pages (default: working directory)

       --web-conf
              name of the hgweb config file (see "hg help hgweb")

       --webdir-conf
              name of the hgweb config file (DEPRECATED)

       --pid-file
              name of file to write process ID to

       --stdio
              for remote clients

       --cmdserver
              for remote clients

       -t, --templates
              web templates to use

       --style
              template style to use

       -6, --ipv6
              use IPv6 in addition to IPv4

       --certificate
              SSL certificate file

   showconfig
       hg showconfig [-u] [NAME]...

       With no arguments, print names and values of all config items.

       With one argument of the form section.name, print just the value of that config item.

       With multiple arguments, print names and values of all config items with matching section names.

       With --debug, the source (filename and line number) is printed for each config item.

       Returns 0 on success.

       Options:

       -u, --untrusted
              show untrusted configuration options

              aliases: debugconfig

   status
       hg status [OPTION]... [FILE]...

       Show  status  of files in the repository. If names are given, only files that match are shown. Files that
       are clean or ignored or  the  source  of  a  copy/move  operation,  are  not  listed  unless  -c/--clean,
       -i/--ignored,  -C/--copies  or  -A/--all  are  given.   Unless options described with "show only ..." are
       given, the options -mardu are used.

       Option  -q/--quiet  hides  untracked  (unknown  and  ignored)  files  unless  explicitly  requested  with
       -u/--unknown or -i/--ignored.

       Note   status  may  appear to disagree with diff if permissions have changed or a merge has occurred. The
              standard diff format does not report permission changes and diff only reports changes relative  to
              one merge parent.

       If  one  revision is given, it is used as the base revision.  If two revisions are given, the differences
       between them are shown. The --change option can also be used as a shortcut to list the changed files of a
       revision from its first parent.

       The codes used to show the status of files are:

       M = modified
       A = added
       R = removed
       C = clean
       ! = missing (deleted by non-hg command, but still tracked)
       ? = not tracked
       I = ignored
         = origin of the previous file listed as A (added)

       Examples:

       • show changes in the working directory relative to a changeset:

         hg status --rev 9353

       • show all changes including copies in an existing changeset:

         hg status --copies --change 9353

       • get a NUL separated list of added files, suitable for xargs:

         hg status -an0

       Returns 0 on success.

       Options:

       -A, --all
              show status of all files

       -m, --modified
              show only modified files

       -a, --added
              show only added files

       -r, --removed
              show only removed files

       -d, --deleted
              show only deleted (but tracked) files

       -c, --clean
              show only files without changes

       -u, --unknown
              show only unknown (not tracked) files

       -i, --ignored
              show only ignored files

       -n, --no-status
              hide status prefix

       -C, --copies
              show source of copied files

       -0, --print0
              end filenames with NUL, for use with xargs

       --rev  show difference from revision

       --change
              list the changed files of a revision

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   summary
       hg summary [--remote]

       This generates a brief summary of the working directory state, including parents, branch, commit  status,
       and available updates.

       With  the  --remote option, this will check the default paths for incoming and outgoing changes. This can
       be time-consuming.

       Returns 0 on success.

       Options:

       --remote
              check for push and pull

              aliases: sum

   tag
       hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...

       Name a particular revision using <name>.

       Tags are used to name particular revisions of the repository and are very  useful  to  compare  different
       revisions, to go back to significant earlier versions or to mark branch points as releases, etc. Changing
       an existing tag is normally disallowed; use -f/--force to override.

       If no revision is given, the parent of the working directory is used.

       To  facilitate  version  control,  distribution,  and  merging  of  tags, they are stored as a file named
       ".hgtags" which is managed similarly to other project files and can be  hand-edited  if  necessary.  This
       also means that tagging creates a new commit. The file ".hg/localtags" is used for local tags (not shared
       among repositories).

       Tag  commits  are  usually  made at the head of a branch. If the parent of the working directory is not a
       branch head, hg tag aborts; use -f/--force to force the tag commit to be based on a non-head changeset.

       See hg help dates for a list of formats valid for -d/--date.

       Since tag names have priority over branch names during revision lookup, using an existing branch name  as
       a tag name is discouraged.

       Returns 0 on success.

       Options:

       -f, --force
              force tag

       -l, --local
              make the tag local

       -r, --rev
              revision to tag

       --remove
              remove a tag

       -e, --edit
              edit commit message

       -m, --message
              use <text> as commit message

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

   tags
       hg tags

       This  lists  both regular and local tags. When the -v/--verbose switch is used, a third column "local" is
       printed for local tags.

       Returns 0 on success.

   tip
       hg tip [-p] [-g]

       The tip revision (usually just called the tip) is the changeset most recently  added  to  the  repository
       (and therefore the most recently changed head).

       If you have just made a commit, that commit will be the tip. If you have just pulled changes from another
       repository,  the  tip  of that repository becomes the current tip. The "tip" tag is special and cannot be
       renamed or assigned to a different changeset.

       This command is deprecated, please use hg heads instead.

       Returns 0 on success.

       Options:

       -p, --patch
              show patch

       -g, --git
              use git extended diff format

       --style
              display using template map file

       --template
              display with template

   unbundle
       hg unbundle [-u] FILE...

       Apply one or more compressed changegroup files generated by the bundle command.

       Returns 0 on success, 1 if an update has unresolved files.

       Options:

       -u, --update
              update to new branch head if changesets were unbundled

   update
       hg update [-c] [-C] [-d DATE] [[-r] REV]

       Update the repository's working directory to the specified  changeset.  If  no  changeset  is  specified,
       update to the tip of the current named branch and move the current bookmark (see hg help bookmarks).

       Update sets the working directory's parent revision to the specified changeset (see hg help parents).

       If  the  changeset  is  not  a  descendant  or  ancestor of the working directory's parent, the update is
       aborted. With the -c/--check option, the working directory is checked for uncommitted  changes;  if  none
       are found, the working directory is updated to the specified changeset.

       The following rules apply when the working directory contains uncommitted changes:

       1. If  neither  -c/--check  nor -C/--clean is specified, and if the requested changeset is an ancestor or
          descendant of the working directory's parent, the uncommitted changes are merged  into  the  requested
          changeset  and the merged result is left uncommitted. If the requested changeset is not an ancestor or
          descendant (that is, it is on another branch), the update is aborted and the uncommitted  changes  are
          preserved.

       2. With the -c/--check option, the update is aborted and the uncommitted changes are preserved.

       3. With  the -C/--clean option, uncommitted changes are discarded and the working directory is updated to
          the requested changeset.

       To cancel an uncommitted merge (and lose your changes), use hg update --clean ..

       Use null as the changeset to remove the working directory (like hg clone -U).

       If you want to revert just one file to an older revision, use hg revert [-r REV] NAME.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success, 1 if there are unresolved files.

       Options:

       -C, --clean
              discard uncommitted changes (no backup)

       -c, --check
              update across branches if no uncommitted changes

       -d, --date
              tipmost revision matching date

       -r, --rev
              revision

              aliases: up checkout co

   verify
       hg verify

       Verify the integrity of the current repository.

       This will perform an extensive check of the repository's integrity, validating the hashes  and  checksums
       of each entry in the changelog, manifest, and tracked files, as well as the integrity of their crosslinks
       and indices.

       Please  see  http://mercurial.selenic.com/wiki/RepositoryCorruption for  more  information about recovery
       from corruption of the repository.

       Returns 0 on success, 1 if errors are encountered.

   version
       hg version

       output version and copyright information

DATE FORMATS

       Some commands allow the user to specify a date, e.g.:

       • backout, commit, import, tag: Specify the commit date.

       • log, revert, update: Select revision(s) by date.

       Many date formats are valid. Here are some examples:

       • Wed Dec 6 13:18:29 2006 (local timezone assumed)

       • Dec 6 13:18 -0600 (year assumed, time offset provided)

       • Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)

       • Dec 6 (midnight)

       • 13:18 (today assumed)

       • 3:39 (3:39AM assumed)

       • 3:39pm (15:39)

       • 2006-12-06 13:18:29 (ISO 8601 format)

       • 2006-12-6 13:182006-12-612-612/612/6/6 (Dec 6 2006)

       • today (midnight)

       • yesterday (midnight)

       • now - right now

       Lastly, there is Mercurial's internal format:

       • 1165411109 0 (Wed Dec 6 13:18:29 2006 UTC)

       This is the internal representation format for dates. The first number is the number of seconds since the
       epoch (1970-01-01 00:00 UTC). The second is the offset of the local timezone,  in  seconds  west  of  UTC
       (negative if the timezone is east of UTC).

       The log command also accepts date ranges:

       • <DATE - at or before a given date/time

       • >DATE - on or after a given date/time

       • DATE to DATE - a date range, inclusive

       • -DAYS - within a given number of days of today

DIFF FORMATS

       Mercurial's  default  format  for  showing  changes between two versions of a file is compatible with the
       unified format of GNU diff, which can be used by GNU patch and many other standard tools.

       While this standard format is often enough, it does not encode the following information:

       • executable status and other permission bits

       • copy or rename information

       • changes in binary files

       • creation or deletion of empty files

       Mercurial also supports the extended diff format from the git VCS which addresses these limitations.  The
       git  diff  format  is not produced by default because a few widespread tools still do not understand this
       format.

       This means that when generating diffs from a Mercurial repository (e.g. with hg export),  you  should  be
       careful  about things like file copies and renames or other things mentioned above, because when applying
       a standard diff to  a  different  repository,  this  extra  information  is  lost.  Mercurial's  internal
       operations  (like push and pull) are not affected by this, because they use an internal binary format for
       communicating changes.

       To make Mercurial produce the git extended diff format, use the --git option available for many commands,
       or set 'git = True' in the [diff] section of your configuration file. You do not need to set this  option
       when importing diffs in this format or using them in the mq extension.

ENVIRONMENT VARIABLES

       HG     Path  to  the  'hg'  executable,  automatically  passed when running hooks, extensions or external
              tools. If unset or empty, this is the hg executable's name if it's frozen, or an executable  named
              'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Windows) is searched.

       HGEDITOR
              This is the name of the editor to run when committing. See EDITOR.

              (deprecated, use configuration file)

       HGENCODING
              This  overrides the default locale setting detected by Mercurial.  This setting is used to convert
              data including usernames, changeset descriptions, tag names, and branches.  This  setting  can  be
              overridden with the --encoding command-line option.

       HGENCODINGMODE
              This  sets  Mercurial's behavior for handling unknown characters while transcoding user input. The
              default is "strict", which causes Mercurial to abort if it can't map a character.  Other  settings
              include "replace", which replaces unknown characters, and "ignore", which drops them. This setting
              can be overridden with the --encodingmode command-line option.

       HGENCODINGAMBIGUOUS
              This sets Mercurial's behavior for handling characters with "ambiguous" widths like accented Latin
              characters  with  East Asian fonts. By default, Mercurial assumes ambiguous characters are narrow,
              set this variable to "wide" if such characters cause formatting problems.

       HGMERGE
              An executable to use for resolving merge conflicts.  The  program  will  be  executed  with  three
              arguments: local file, remote file, ancestor file.

              (deprecated, use configuration file)

       HGRCPATH
              A  list  of files or directories to search for configuration files. Item separator is ":" on Unix,
              ";" on Windows. If HGRCPATH is not set, platform default search path is used. If empty,  only  the
              .hg/hgrc from the current repository is read.

              For each element in HGRCPATH:

              • if it's a directory, all files ending with .rc are added

              • otherwise, the file itself will be added

       HGPLAIN
              When  set,  this disables any configuration settings that might change Mercurial's default output.
              This  includes  encoding,  defaults,  verbose  mode,  debug  mode,  quiet  mode,  tracebacks,  and
              localization.  This  can  be  useful when scripting against Mercurial in the face of existing user
              configuration.

              Equivalent options set via command line flags or environment variables are not overridden.

       HGPLAINEXCEPT
              This is a comma-separated list of features to preserve when HGPLAIN is enabled. Currently the only
              value supported is "i18n", which preserves internationalization in plain mode.

              Setting HGPLAINEXCEPT to anything (even an empty string) will enable plain mode.

       HGUSER This is the string used as the author of a commit. If not set, available values will be considered
              in this order:

              • HGUSER (deprecated)

              • configuration files from the HGRCPATH

              • EMAIL

              • interactive prompt

              • LOGNAME (with @hostname appended)

              (deprecated, use configuration file)

       EMAIL  May be used as the author of a commit; see HGUSER.

       LOGNAME
              May be used as the author of a commit; see HGUSER.

       VISUAL This is the name of the editor to use when committing. See EDITOR.

       EDITOR Sometimes Mercurial needs to open a text file in an editor for a user to modify, for example  when
              writing  commit messages. The editor it uses is determined by looking at the environment variables
              HGEDITOR, VISUAL and EDITOR, in that order. The first non-empty one is chosen. If all of them  are
              empty, the editor defaults to 'sensible-editor'.

       PYTHONPATH
              This  is  used  by  Python  to  find imported modules and may need to be set appropriately if this
              Mercurial is not installed system-wide.

USING ADDITIONAL FEATURES

       Mercurial has the ability to add new features through the use  of  extensions.  Extensions  may  add  new
       commands, add options to existing commands, change the default behavior of commands, or implement hooks.

       To  enable  the  "foo"  extension,  either shipped with Mercurial or in the Python search path, create an
       entry for it in your configuration file, like this:

       [extensions]
       foo =

       You may also specify the full path to an extension:

       [extensions]
       myfeature = ~/.hgext/myfeature.py

       See hg help config for more information on configuration files.

       Extensions are not loaded by default for a variety of reasons: they can increase startup  overhead;  they
       may  be  meant for advanced usage only; they may provide potentially dangerous abilities (such as letting
       you destroy or modify history); they might not be ready for prime time; or  they  may  alter  some  usual
       behaviors of stock Mercurial. It is thus up to the user to activate extensions as needed.

       To  explicitly  disable  an  extension enabled in a configuration file of broader scope, prepend its path
       with !:

       [extensions]
       # disabling extension bar residing in /path/to/extension/bar.py
       bar = !/path/to/extension/bar.py
       # ditto, but no path was supplied for extension baz
       baz = !

       disabled extensions:

SPECIFYING FILE SETS

       Mercurial supports a functional language for selecting a set of files.

       Like other file patterns, this pattern type is indicated by a prefix, 'set:'.  The  language  supports  a
       number of predicates which are joined by infix operators. Parenthesis can be used for grouping.

       Identifiers  such  as  filenames  or patterns must be quoted with single or double quotes if they contain
       characters outside of [.*{}[]?/\_a-zA-Z0-9\x80-\xff] or if they match one of the  predefined  predicates.
       This generally applies to file patterns other than globs and arguments for predicates.

       Special  characters  can  be  used  in  quoted identifiers by escaping them, e.g., \n is interpreted as a
       newline. To prevent them from being interpreted, strings can be prefixed with r, e.g. r'...'.

       There is a single prefix operator:

       not x

              Files not in x. Short form is ! x.

       These are the supported infix operators:

       x and y

              The intersection of files in x and y. Short form is x & y.

       x or y

              The union of files in x and y. There are two alternative short forms: x | y and x + y.

       x - y

              Files in x but not in y.

       The following predicates are supported:

       added()

              File that is added according to status.

       binary()

              File that appears to be binary (contains NUL bytes).

       clean()

              File that is clean according to status.

       copied()

              File that is recorded as being copied.

       deleted()

              File that is deleted according to status.

       encoding(name)

              File can be successfully decoded with  the  given  character  encoding.  May  not  be  useful  for
              encodings other than ASCII and UTF-8.

       eol(style)

              File  contains newlines of the given style (dos, unix, mac). Binary files are excluded, files with
              mixed line endings match multiple styles.

       exec()

              File that is marked as executable.

       grep(regex)

              File contains the given regular expression.

       hgignore()

              File that matches the active .hgignore pattern.

       ignored()

              File that is ignored according to status. These files will only be considered if this predicate is
              used.

       modified()

              File that is modified according to status.

       removed()

              File that is removed according to status.

       resolved()

              File that is marked resolved according to the resolve state.

       size(expression)

              File size matches the given expression. Examples:

              • 1k (files from 1024 to 2047 bytes)

              • < 20k (files less than 20480 bytes)

              • >= .5MB (files at least 524288 bytes)

              • 4k - 1MB (files from 4096 bytes to 1048576 bytes)

       subrepo([pattern])

              Subrepositories whose paths match the given pattern.

       symlink()

              File that is marked as a symlink.

       unknown()

              File that is unknown according to status. These files will only be considered if this predicate is
              used.

       unresolved()

              File that is marked unresolved according to the resolve state.

       Some sample queries:

       • Show status of files that appear to be binary in the working directory:

         hg status -A "set:binary()"

       • Forget files that are in .hgignore but are already tracked:

         hg forget "set:hgignore() and not ignored()"

       • Find text files that contain a string:

         hg locate "set:grep(magic) and not binary()"

       • Find C files in a non-standard encoding:

         hg locate "set:**.c and not encoding('UTF-8')"

       • Revert copies of large binary files:

         hg revert "set:copied() and binary() and size('>1M')"

       • Remove files listed in foo.lst that contain the letter a or b:

         hg remove "set: 'listfile:foo.lst' and (**a* or **b*)"

       See also hg help patterns.

GLOSSARY

       Ancestor
              Any changeset that can be reached  by  an  unbroken  chain  of  parent  changesets  from  a  given
              changeset. More precisely, the ancestors of a changeset can be defined by two properties: a parent
              of a changeset is an ancestor, and a parent of an ancestor is an ancestor. See also: 'Descendant'.

       Bookmark
              Bookmarks  are  pointers to certain commits that move when committing. They are similar to tags in
              that it is possible to use bookmark names in all places where Mercurial expects  a  changeset  ID,
              e.g., with hg update. Unlike tags, bookmarks move along when you make a commit.

              Bookmarks  can  be  renamed,  copied  and deleted. Bookmarks are local, unless they are explicitly
              pushed or pulled between repositories.  Pushing and pulling bookmarks  allow  you  to  collaborate
              with others on a branch without creating a named branch.

       Branch (Noun)  A  child changeset that has been created from a parent that is not a head. These are known
              as topological branches, see 'Branch, topological'. If a topological branch is named, it becomes a
              named branch. If a topological branch is not named, it becomes an anonymous branch.  See  'Branch,
              anonymous' and 'Branch, named'.

              Branches  may  be created when changes are pulled from or pushed to a remote repository, since new
              heads may be created by these operations. Note that the term branch can also be used informally to
              describe a development process in  which  certain  development  is  done  independently  of  other
              development.  This  is  sometimes  done  explicitly  with  a named branch, but it can also be done
              locally, using bookmarks or clones and anonymous branches.

              Example: "The experimental branch".

              (Verb) The action of creating a child changeset which results in its parent having more  than  one
              child.

              Example: "I'm going to branch at X".

       Branch, anonymous
              Every  time  a new child changeset is created from a parent that is not a head and the name of the
              branch is not changed, a new anonymous branch is created.

       Branch, closed
              A named branch whose branch heads have all been closed.

       Branch, default
              The branch assigned to a changeset when no name has previously been assigned.

       Branch head
              See 'Head, branch'.

       Branch, inactive
              If a named branch has no topological heads, it is considered to be  inactive.  As  an  example,  a
              feature branch becomes inactive when it is merged into the default branch. The hg branches command
              shows inactive branches by default, though they can be hidden with hg branches --active.

              NOTE:  this  concept  is deprecated because it is too implicit.  Branches should now be explicitly
              closed using hg commit --close-branch when they are no longer needed.

       Branch, named
              A collection of changesets which have the same branch name. By default, children of a changeset in
              a named branch belong to the same named branch. A child can be explicitly assigned to a  different
              branch.  See hg help branch, hg help branches and hg commit --close-branch for more information on
              managing branches.

              Named branches can be thought of as a kind of namespace, dividing  the  collection  of  changesets
              that  comprise  the  repository  into  a  collection  of  disjoint  subsets. A named branch is not
              necessarily a topological branch. If a new named branch is created from the head of another  named
              branch,  or  the default branch, but no further changesets are added to that previous branch, then
              that previous branch will be a branch in name only.

       Branch tip
              See 'Tip, branch'.

       Branch, topological
              Every time a new child changeset is created from a parent that is not a head,  a  new  topological
              branch  is  created. If a topological branch is named, it becomes a named branch. If a topological
              branch is not named, it becomes an anonymous branch of the current, possibly default, branch.

       Changelog
              A record of the changesets in the order in which they were added to the repository. This  includes
              details such as changeset id, author, commit message, date, and list of changed files.

       Changeset
              A snapshot of the state of the repository used to record a change.

       Changeset, child
              The converse of parent changeset: if P is a parent of C, then C is a child of P. There is no limit
              to the number of children that a changeset may have.

       Changeset id
              A  SHA-1  hash  that  uniquely identifies a changeset. It may be represented as either a "long" 40
              hexadecimal digit string, or a "short" 12 hexadecimal digit string.

       Changeset, merge
              A changeset with two parents. This occurs when a merge is committed.

       Changeset, parent
              A revision upon which a child changeset is based. Specifically, a parent changeset of a  changeset
              C  is  a  changeset  whose  node  immediately  precedes  C in the DAG. Changesets have at most two
              parents.

       Checkout
              (Noun) The working directory being updated to a specific revision. This  use  should  probably  be
              avoided where possible, as changeset is much more appropriate than checkout in this context.

              Example: "I'm using checkout X."

              (Verb) Updating the working directory to a specific changeset. See hg help update.

              Example: "I'm going to check out changeset X."

       Child changeset
              See 'Changeset, child'.

       Close changeset
              See 'Head, closed branch'

       Closed branch
              See 'Branch, closed'.

       Clone  (Noun)  An  entire  or  partial  copy  of a repository. The partial clone must be in the form of a
              revision and its ancestors.

              Example: "Is your clone up to date?".

              (Verb) The process of creating a clone, using hg clone.

              Example: "I'm going to clone the repository".

       Closed branch head
              See 'Head, closed branch'.

       Commit (Noun) A synonym for changeset.

              Example: "Is the bug fixed in your recent commit?"

              (Verb) The act of recording changes to a  repository.  When  files  are  committed  in  a  working
              directory, Mercurial finds the differences between the committed files and their parent changeset,
              creating a new changeset in the repository.

              Example: "You should commit those changes now."

       Cset   A common abbreviation of the term changeset.

       DAG    The  repository of changesets of a distributed version control system (DVCS) can be described as a
              directed acyclic graph (DAG), consisting of nodes and edges, where nodes correspond to  changesets
              and  edges  imply a parent -> child relation. This graph can be visualized by graphical tools such
              as hg log --graph. In Mercurial, the DAG is limited by the requirement for  children  to  have  at
              most two parents.

       Default branch
              See 'Branch, default'.

       Descendant
              Any  changeset  that  can  be  reached by a chain of child changesets from a given changeset. More
              precisely, the descendants of a changeset can be  defined  by  two  properties:  the  child  of  a
              changeset is a descendant, and the child of a descendant is a descendant. See also: 'Ancestor'.

       Diff   (Noun)  The  difference  between  the  contents  and  attributes  of  files in two changesets or a
              changeset and the current working directory. The difference is usually represented in  a  standard
              form  called  a  "diff" or "patch". The "git diff" format is used when the changes include copies,
              renames, or changes to file attributes, none of which can be represented/handled by classic "diff"
              and "patch".

              Example: "Did you see my correction in the diff?"

              (Verb) Diffing two changesets is the action of creating a diff or patch.

              Example: "If you diff with changeset X, you will see what I mean."

       Directory, working
              The working directory represents the state of  the  files  tracked  by  Mercurial,  that  will  be
              recorded  in  the  next  commit. The working directory initially corresponds to the snapshot at an
              existing changeset, known as the parent of the working directory. See 'Parent, working directory'.
              The state may be modified by changes  to  the  files  introduced  manually  or  by  a  merge.  The
              repository metadata exists in the .hg directory inside the working directory.

       Draft  Changesets  in  the  draft phase have not been shared with publishing repositories and may thus be
              safely changed by history-modifying extensions. See hg help phases.

       Graph  See DAG and hg log --graph.

       Head   The term 'head' may be used to refer to both a branch head or a repository head, depending on  the
              context. See 'Head, branch' and 'Head, repository' for specific definitions.

              Heads  are  where development generally takes place and are the usual targets for update and merge
              operations.

       Head, branch
              A changeset with no descendants on the same named branch.

       Head, closed branch
              A changeset that marks a head as no longer interesting. The closed head is no longer listed by  hg
              heads.  A branch is considered closed when all its heads are closed and consequently is not listed
              by hg branches.

              Closed heads can be re-opened by committing new changeset as the child of the changeset that marks
              a head as closed.

       Head, repository
              A topological head which has not been closed.

       Head, topological
              A changeset with no children in the repository.

       History, immutable
              Once committed, changesets cannot be altered.  Extensions which appear to change history  actually
              create new changesets that replace existing ones, and then destroy the old changesets. Doing so in
              public repositories can result in old changesets being reintroduced to the repository.

       History, rewriting
              The  changesets  in  a  repository  are immutable. However, extensions to Mercurial can be used to
              alter the repository, usually in such a way as to preserve changeset contents.

       Immutable history
              See 'History, immutable'.

       Merge changeset
              See 'Changeset, merge'.

       Manifest
              Each changeset has a manifest, which is the list of files that are tracked by the changeset.

       Merge  Used to bring together divergent branches of work. When you update to a changeset and  then  merge
              another changeset, you bring the history of the latter changeset into your working directory. Once
              conflicts  are  resolved  (and marked), this merge may be committed as a merge changeset, bringing
              two branches together in the DAG.

       Named branch
              See 'Branch, named'.

       Null changeset
              The empty changeset. It is the parent state of  newly-initialized  repositories  and  repositories
              with  no checked out revision. It is thus the parent of root changesets and the effective ancestor
              when merging unrelated changesets. Can be specified by the alias 'null' or  by  the  changeset  ID
              '000000000000'.

       Parent See 'Changeset, parent'.

       Parent changeset
              See 'Changeset, parent'.

       Parent, working directory
              The  working  directory parent reflects a virtual revision which is the child of the changeset (or
              two changesets with an uncommitted merge) shown by hg parents. This is  changed  with  hg  update.
              Other  commands  to see the working directory parent are hg summary and hg id. Can be specified by
              the alias ".".

       Patch  (Noun) The product of a diff operation.

              Example: "I've sent you my patch."

              (Verb) The process of using a patch file to transform one changeset into another.

              Example: "You will need to patch that revision."

       Phase  A per-changeset state tracking how the changeset has been or should be shared. See hg help phases.

       Public Changesets in the public phase have been shared with publishing  repositories  and  are  therefore
              considered immutable. See hg help phases.

       Pull   An  operation in which changesets in a remote repository which are not in the local repository are
              brought into the local repository. Note that this operation without special arguments only updates
              the repository, it does not update the files in the working directory. See hg help pull.

       Push   An operation in which changesets in a local repository which are not in a  remote  repository  are
              sent  to  the  remote  repository.  Note  that this operation only adds changesets which have been
              committed locally to the remote repository. Uncommitted changes are not sent. See hg help push.

       Repository
              The metadata describing all recorded states of a collection  of  files.  Each  recorded  state  is
              represented by a changeset. A repository is usually (but not always) found in the .hg subdirectory
              of a working directory. Any recorded state can be recreated by "updating" a working directory to a
              specific changeset.

       Repository head
              See 'Head, repository'.

       Revision
              A  state  of the repository at some point in time. Earlier revisions can be updated to by using hg
              update.  See also 'Revision number'; See also 'Changeset'.

       Revision number
              This integer uniquely identifies a changeset in a specific repository. It represents the order  in
              which  changesets  were  added  to  a  repository,  starting with revision number 0. Note that the
              revision number may be different in each clone of a repository. To  identify  changesets  uniquely
              between different clones, see 'Changeset id'.

       Revlog History  storage mechanism used by Mercurial. It is a form of delta encoding, with occasional full
              revision of data followed by delta of each successive revision. It  includes  data  and  an  index
              pointing to the data.

       Rewriting history
              See 'History, rewriting'.

       Root   A  changeset  that has only the null changeset as its parent. Most repositories have only a single
              root changeset.

       Secret Changesets in the secret phase may not be shared via push, pull, or clone. See hg help phases.

       Tag    An alternative name given to a changeset. Tags can be used in all places where Mercurial expects a
              changeset ID, e.g., with hg update. The creation of a tag is stored in the history and  will  thus
              automatically be shared with other using push and pull.

       Tip    The  changeset  with  the  highest  revision  number. It is the changeset most recently added in a
              repository.

       Tip, branch
              The head of a given branch with the highest revision number. When a  branch  name  is  used  as  a
              revision  identifier,  it  refers  to  the  branch tip. See also 'Branch, head'. Note that because
              revision numbers may be different in different repository clones, the branch tip may be  different
              in different cloned repositories.

       Update (Noun) Another synonym of changeset.

              Example: "I've pushed an update".

              (Verb)  This  term is usually used to describe updating the state of the working directory to that
              of a specific changeset. See hg help update.

              Example: "You should update".

       Working directory
              See 'Directory, working'.

       Working directory parent
              See 'Parent, working directory'.

SYNTAX FOR MERCURIAL IGNORE FILES

   Synopsis
       The Mercurial system uses a file called .hgignore in the root directory of a repository  to  control  its
       behavior when it searches for files that it is not currently tracking.

   Description
       The  working  directory  of a Mercurial repository will often contain files that should not be tracked by
       Mercurial. These include backup files created by editors and build products created by compilers.   These
       files  can  be  ignored  by  listing  them  in a .hgignore file in the root of the working directory. The
       .hgignore file must be created manually. It is typically put under version control, so that the  settings
       will propagate to other repositories with push and pull.

       An untracked file is ignored if its path relative to the repository root directory, or any prefix path of
       that path, is matched against any pattern in .hgignore.

       For  example,  say we have an untracked file, file.c, at a/b/file.c inside our repository. Mercurial will
       ignore file.c if any pattern in .hgignore matches a/b/file.c, a/b or a.

       In addition, a Mercurial configuration file can reference a set of per-user or global ignore  files.  See
       the  ignore configuration key on the [ui] section of hg help config for details of how to configure these
       files.

       To control Mercurial's handling of files that it manages, many commands support the -I  and  -X  options;
       see hg help <command> and hg help patterns for details.

       Files  that  are  already  tracked  are  not  affected by .hgignore, even if they appear in .hgignore. An
       untracked file X can be explicitly added with hg add X, even if X would  be  excluded  by  a  pattern  in
       .hgignore.

   Syntax
       An  ignore  file  is a plain text file consisting of a list of patterns, with one pattern per line. Empty
       lines are skipped. The # character is treated as a comment character, and the \ character is  treated  as
       an escape character.

       Mercurial  supports  several  pattern  syntaxes.  The  default  syntax  used is Python/Perl-style regular
       expressions.

       To change the syntax used, use a line of the following form:

       syntax: NAME

       where NAME is one of the following:

       regexp

              Regular expression, Python/Perl syntax.

       glob

              Shell-style glob.

       The chosen syntax stays in effect when  parsing  all  patterns  that  follow,  until  another  syntax  is
       selected.

       Neither  glob  nor  regexp  patterns  are rooted. A glob-syntax pattern of the form *.c will match a file
       ending in .c in any directory, and a regexp pattern of the form \.c$ will do the same. To root  a  regexp
       pattern, start it with ^.

       Note   Patterns  specified  in  other  than .hgignore are always rooted.  Please see hg help patterns for
              details.

   Example
       Here is an example ignore file.

       # use glob syntax.
       syntax: glob

       *.elc
       *.pyc
       *~

       # switch to regexp syntax.
       syntax: regexp
       ^\.pc/

CONFIGURING HGWEB

       Mercurial's internal web server, hgweb, can serve either a single repository, or a tree of  repositories.
       In  the  second  case, repository paths and global options can be defined using a dedicated configuration
       file common to hg serve, hgweb.wsgi, hgweb.cgi and hgweb.fcgi.

       This file uses the same syntax as other Mercurial configuration files but recognizes only  the  following
       sections:

          • web

          • paths

          • collections

       The web options are thoroughly described in hg help config.

       The  paths  section  maps URL paths to paths of repositories in the filesystem. hgweb will not expose the
       filesystem  directly  -  only  Mercurial  repositories  can  be  published  and  only  according  to  the
       configuration.

       The  left hand side is the path in the URL. Note that hgweb reserves subpaths like rev or file, try using
       different names for nested repositories to avoid confusing effects.

       The right hand side is the path in the filesystem. If the specified path ends with * or ** the filesystem
       will be searched recursively for repositories below that point.  With * it  will  not  recurse  into  the
       repositories  it  finds  (except for .hg/patches).  With ** it will also search inside repository working
       directories and possibly find subrepositories.

       In this example:

       [paths]
       /projects/a = /srv/tmprepos/a
       /projects/b = c:/repos/b
       / = /srv/repos/*
       /user/bob = /home/bob/repos/**

       • The first two entries make two repositories in different directories appear under the same directory in
         the web interface

       • The third entry will publish  every  Mercurial  repository  found  in  /srv/repos/,  for  instance  the
         repository /srv/repos/quux/ will appear as http://server/quux/

       • The       fourth      entry      will      publish      both      http://server/user/bob/quux/      and
         http://server/user/bob/quux/testsubrepo/

       The collections section is deprecated and has been superseded by paths.

MERGE TOOLS

       To merge files Mercurial uses merge tools.

       A merge tool combines two different versions of a file into a merged file. Merge tools are given the  two
       files  and  the greatest common ancestor of the two file versions, so they can determine the changes made
       on both branches.

       Merge tools are used both for hg resolve, hg merge, hg update, hg backout and in several extensions.

       Usually, the merge tool tries to automatically reconcile  the  files  by  combining  all  non-overlapping
       changes  that  occurred  separately  in  the  two  different  evolutions  of  the same initial base file.
       Furthermore, some interactive merge programs make it  easier  to  manually  resolve  conflicting  merges,
       either  in  a  graphical  way,  or  by  inserting  some  conflict markers. Mercurial does not include any
       interactive merge programs but relies on external tools for that.

   Available merge tools
       External merge tools and their properties are configured in the merge-tools configuration section  -  see
       hgrc(5) - but they can often just be named by their executable.

       A  merge  tool  is generally usable if its executable can be found on the system and if it can handle the
       merge. The executable is found if it is an absolute or  relative  executable  path  or  the  name  of  an
       application  in  the executable search path. The tool is assumed to be able to handle the merge if it can
       handle symlinks if the file is a symlink, if it can handle binary files if the file is binary, and  if  a
       GUI is available if the tool requires a GUI.

       There are some internal merge tools which can be used. The internal merge tools are:

       internal:dump

              Creates  three  versions  of the files to merge, containing the contents of local, other and base.
              These files can then be used to perform a merge manually. If the file to be merged is named a.txt,
              these files will accordingly be named a.txt.local, a.txt.other and a.txt.base  and  they  will  be
              placed in the same directory as a.txt.

       internal:fail

              Rather  than  attempting  to  merge  files  that  were modified on both branches, it marks them as
              unresolved. The resolve command must be used to resolve these conflicts.

       internal:local

              Uses the local version of files as the merged version.

       internal:merge

              Uses the internal non-interactive simple merge algorithm for merging files. It will fail if  there
              are any conflicts and leave markers in the partially merged file.

       internal:other

              Uses the other version of files as the merged version.

       internal:prompt

              Asks the user which of the local or the other version to keep as the merged version.

       Internal  tools  are always available and do not require a GUI but will by default not handle symlinks or
       binary files.

   Choosing a merge tool
       Mercurial uses these rules when deciding which merge tool to use:

       1. If a tool has been specified with the --tool option to merge or resolve, it is used.   If  it  is  the
          name  of  a  tool in the merge-tools configuration, its configuration is used. Otherwise the specified
          tool must be executable by the shell.

       2. If the HGMERGE environment variable is present, its value is used and must be executable by the shell.

       3. If the filename of the  file  to  be  merged  matches  any  of  the  patterns  in  the  merge-patterns
          configuration  section, the first usable merge tool corresponding to a matching pattern is used. Here,
          binary capabilities of the merge tool are not considered.

       4. If ui.merge is set it will be considered next. If the value is not the name of a configured tool,  the
          specified value is used and must be executable by the shell. Otherwise the named tool is used if it is
          usable.

       5. If  any  usable  merge  tools  are  present in the merge-tools configuration section, the one with the
          highest priority is used.

       6. If a program named hgmerge can be found on the system, it is used - but it will by default not be used
          for symlinks and binary files.

       7. If the file to be merged is not binary and is not a symlink, then internal:merge is used.

       8. The merge of the file fails and must be resolved before commit.

       Note   After selecting a merge program, Mercurial will by default attempt to  merge  the  files  using  a
              simple  merge algorithm first. Only if it doesn't succeed because of conflicting changes Mercurial
              will actually execute the merge program. Whether to use the simple merge algorithm  first  can  be
              controlled  by  the  premerge setting of the merge tool. Premerge is enabled by default unless the
              file is binary or a symlink.

       See the merge-tools and ui sections of hgrc(5) for details on the configuration of merge tools.

SPECIFYING MULTIPLE REVISIONS

       When Mercurial accepts more than one revision, they may be  specified  individually,  or  provided  as  a
       topologically continuous range, separated by the ":" character.

       The  syntax  of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN
       and END are optional. If BEGIN is not specified, it  defaults  to  revision  number  0.  If  END  is  not
       specified, it defaults to the tip. The range ":" thus means "all revisions".

       If BEGIN is greater than END, revisions are treated in reverse order.

       A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of
       9:6 gives 9, 8, 7, and 6.

FILE NAME PATTERNS

       Mercurial accepts several notations for identifying one or more files at a time.

       By default, Mercurial treats filenames as shell-style extended glob patterns.

       Alternate pattern notations must be specified explicitly.

       Note   Patterns specified in .hgignore are not rooted.  Please see hg help hgignore for details.

       To  use  a  plain  path  name  without  any  pattern matching, start it with path:. These path names must
       completely match starting at the current repository root.

       To use an extended glob, start a name with glob:. Globs are rooted at the current directory; a glob  such
       as *.c will only match files in the current directory ending with .c.

       The  supported glob syntax extensions are ** to match any string across path separators and {a,b} to mean
       "a or b".

       To use a Perl/Python regular expression, start a name with re:.  Regexp pattern matching is  anchored  at
       the root of the repository.

       To  read  name  patterns  from  a  file,  use listfile: or listfile0:.  The latter expects null delimited
       patterns while the former expects line feeds. Each string read from the file is itself treated as a  file
       pattern.

       Plain examples:

       path:foo/bar   a name bar in a directory named foo in the root
                      of the repository
       path:path:name a file or directory named "path:name"

       Glob examples:

       glob:*.c       any name ending in ".c" in the current directory
       *.c            any name ending in ".c" in the current directory
       **.c           any name ending in ".c" in any subdirectory of the
                      current directory including itself.
       foo/*.c        any name ending in ".c" in the directory foo
       foo/**.c       any name ending in ".c" in any subdirectory of foo
                      including itself.

       Regexp examples:

       re:.*\.c$      any name ending in ".c", anywhere in the repository

       File examples:

       listfile:list.txt  read list from list.txt with one file pattern per line
       listfile0:list.txt read list from list.txt with null byte delimiters

       See also hg help filesets.

WORKING WITH PHASES

   What are phases?
       Phases  are  a  system  for  tracking  which changesets have been or should be shared. This helps prevent
       common mistakes when modifying history (for instance, with the mq or rebase extensions).

       Each changeset in a repository is in one of the following phases:

          • public : changeset is visible on a public server

          • draft : changeset is not yet published

          • secret : changeset should not be pushed, pulled, or cloned

       These phases are ordered (public < draft < secret) and no changeset can be in  a  lower  phase  than  its
       ancestors.  For  instance, if a changeset is public, all its ancestors are also public. Lastly, changeset
       phases should only be changed towards the public phase.

   How are phases managed?
       For the most part, phases should work transparently. By default, a changeset  is  created  in  the  draft
       phase and is moved into the public phase when it is pushed to another repository.

       Once  changesets  become  public, extensions like mq and rebase will refuse to operate on them to prevent
       creating duplicate changesets.  Phases can also be manually manipulated  with  the  hg  phase command  if
       needed. See hg help -v phase for examples.

   Phases and servers
       Normally, all servers are publishing by default. This means:

       - all draft changesets that are pulled or cloned appear in phase
       public on the client

       - all draft changesets that are pushed appear as public on both
       client and server

       - secret changesets are neither pushed, pulled, or cloned

       Note   Pulling  a  draft changeset from a publishing server does not mark it as public on the server side
              due to the read-only nature of pull.

       Sometimes it may be desirable to push and pull changesets in the draft phase to  share  unfinished  work.
       This can be done by setting a repository to disable publishing in its configuration file:

       [phases]
       publish = False

       See hg help config for more information on configuration files.

       Note   Servers running older versions of Mercurial are treated as publishing.

   Examples
          • list changesets in draft or secret phase:

            hg log -r "not public()"

          • change all secret changesets to draft:

            hg phase --draft "secret()"

          • forcibly move the current changeset and descendants from public to draft:

            hg phase --force --draft .

          • show a list of changeset revision and phase:

            hg log --template "{rev} {phase}\n"

          • resynchronize draft changesets relative to a remote repository:

            hg phase -fd "outgoing(URL)"

       See hg help phase for more information on manually manipulating phases.

SPECIFYING SINGLE REVISIONS

       Mercurial supports several ways to specify individual revisions.

       A plain integer is treated as a revision number. Negative integers are treated as sequential offsets from
       the tip, with -1 denoting the tip, -2 denoting the revision prior to the tip, and so forth.

       A 40-digit hexadecimal string is treated as a unique revision identifier.

       A  hexadecimal  string  less  than  40  characters long is treated as a unique revision identifier and is
       referred to as a short-form identifier. A short-form identifier is only valid if  it  is  the  prefix  of
       exactly one full-length identifier.

       Any  other  string  is  treated  as a bookmark, tag, or branch name. A bookmark is a movable pointer to a
       revision. A tag is a permanent name associated with  a  revision.  A  branch  name  denotes  the  tipmost
       revision of that branch. Bookmark, tag, and branch names must not contain the ":" character.

       The reserved name "tip" always identifies the most recent revision.

       The  reserved  name  "null" indicates the null revision. This is the revision of an empty repository, and
       the parent of revision 0.

       The reserved name "." indicates the working directory parent. If no working directory is checked out,  it
       is equivalent to null. If an uncommitted merge is in progress, "." is the revision of the first parent.

SPECIFYING REVISION SETS

       Mercurial supports a functional language for selecting a set of revisions.

       The language supports a number of predicates which are joined by infix operators. Parenthesis can be used
       for grouping.

       Identifiers such as branch names may need quoting with single or double quotes if they contain characters
       like - or if they match one of the predefined predicates.

       Special  characters  can  be  used  in  quoted identifiers by escaping them, e.g., \n is interpreted as a
       newline. To prevent them from being interpreted, strings can be prefixed with r, e.g. r'...'.

       There is a single prefix operator:

       not x

              Changesets not in x. Short form is ! x.

       These are the supported infix operators:

       x::y

              A DAG range, meaning all changesets that are descendants of x and ancestors of y, including x  and
              y themselves. If the first endpoint is left out, this is equivalent to ancestors(y), if the second
              is left out it is equivalent to descendants(x).

              An alternative syntax is x..y.

       x:y

              All  changesets with revision numbers between x and y, both inclusive. Either endpoint can be left
              out, they default to 0 and tip.

       x and y

              The intersection of changesets in x and y. Short form is x & y.

       x or y

              The union of changesets in x and y. There are two alternative short forms: x | y and x + y.

       x - y

              Changesets in x but not in y.

       x^n

              The nth parent of x, n == 0, 1, or 2.  For n == 0, x; for  n  ==  1,  the  first  parent  of  each
              changeset in x; for n == 2, the second parent of changeset in x.

       x~n

              The nth first ancestor of x; x~0 is x; x~3 is x^^^.

       There is a single postfix operator:

       x^

              Equivalent to x^1, the first parent of each changeset in x.

       The following predicates are supported:

       adds(pattern)

              Changesets that add a file matching pattern.

       all()

              All changesets, the same as 0:tip.

       ancestor(*changeset)

              Greatest common ancestor of the changesets.

              Accepts  0  or  more  changesets.   Will  return  empty list when passed no args.  Greatest common
              ancestor of a single changeset is that changeset.

       ancestors(set)

              Changesets that are ancestors of a changeset in set.

       author(string)

              Alias for user(string).

       bisect(string)

              Changesets marked in the specified bisect status:

              • good, bad, skip: csets explicitly marked as good/bad/skip

              • goods, bads      : csets topologically good/bad

              • range              : csets taking part in the bisection

              • pruned             : csets that are goods, bads or skipped

              • untested           : csets whose fate is yet unknown

              • ignored            : csets ignored due to DAG topology

              • current            : the cset currently being bisected

       bookmark([name])

              The named bookmark or all bookmarks.

              If name starts with re:, the remainder of the name is treated as a regular expression. To match  a
              bookmark that actually starts with re:, use the prefix literal:.

       branch(string or set)

              All changesets belonging to the given branch or the branches of the given changesets.

              If  string starts with re:, the remainder of the name is treated as a regular expression. To match
              a branch that actually starts with re:, use the prefix literal:.

       branchpoint()

              Changesets with more than one child.

       bumped()

              Mutable changesets marked as successors of public changesets.

              Only non-public and non-obsolete changesets can be bumped.

       bundle()

              Changesets in the bundle.

              Bundle must be specified by the -R option.

       children(set)

              Child changesets of changesets in set.

       closed()

              Changeset is closed.

       contains(pattern)

              Revision contains a file matching  pattern.  See  hg  help  patterns for  information  about  file
              patterns.

       converted([id])

              Changesets  converted from the given identifier in the old repository if present, or all converted
              changesets if no identifier is specified.

       date(interval)

              Changesets within the interval, see hg help dates.

       desc(string)

              Search commit message for string. The match is case-insensitive.

       descendants(set)

              Changesets which are descendants of changesets in set.

       destination([set])

              Changesets that were created by a graft, transplant or rebase operation, with the given  revisions
              specified as the source.  Omitting the optional set is the same as passing all().

       divergent()

              Final successors of changesets with an alternative set of final successors.

       draft()

              Changeset in draft phase.

       extinct()

              Obsolete changesets with obsolete descendants only.

       extra(label, [value])

              Changesets with the given label in the extra metadata, with the given optional value.

              If  value starts with re:, the remainder of the value is treated as a regular expression. To match
              a value that actually starts with re:, use the prefix literal:.

       file(pattern)

              Changesets affecting files matched by pattern.

              For a faster but less accurate result, consider using filelog() instead.

       filelog(pattern)

              Changesets connected to the specified filelog.

              For performance reasons, filelog() does not  show  every  changeset  that  affects  the  requested
              file(s). See hg help log for details. For a slower, more accurate result, use file().

       first(set, [n])

              An alias for limit().

       follow([file])

              An  alias for ::. (ancestors of the working copy's first parent).  If a filename is specified, the
              history of the given file is followed, including copies.

       grep(regex)

              Like keyword(string) but accepts a regex. Use grep(r'...') to ensure special escape characters are
              handled correctly. Unlike keyword(string), the match is case-sensitive.

       head()

              Changeset is a named branch head.

       heads(set)

              Members of set with no children in set.

       hidden()

              Hidden changesets.

       id(string)

              Revision non-ambiguously specified by the given hex string prefix.

       keyword(string)

              Search commit  message,  user  name,  and  names  of  changed  files  for  string.  The  match  is
              case-insensitive.

       last(set, [n])

              Last n members of set, defaulting to 1.

       limit(set, [n])

              First n members of set, defaulting to 1.

       matching(revision [, field])

              Changesets in which a given set of fields match the set of fields in the selected revision or set.

              To  match  more  than  one field pass the list of fields to match separated by spaces (e.g. author
              description).

              Valid fields are most regular revision fields and some special fields.

              Regular revision fields are description, author, branch, date, files,  phase,  parents,  substate,
              user  and  diff.   Note  that  author  and  user  are synonyms. diff refers to the contents of the
              revision. Two revisions matching their diff will also match their files.

              Special fields are summary and metadata: summary  matches  the  first  line  of  the  description.
              metadata  is  equivalent  to  matching  description  user  date (i.e. it matches the main metadata
              fields).

              metadata is the default field which is used when no fields are specified. You can match more  than
              one field at a time.

       max(set)

              Changeset with highest revision number in set.

       merge()

              Changeset is a merge changeset.

       min(set)

              Changeset with lowest revision number in set.

       modifies(pattern)

              Changesets modifying files matched by pattern.

       obsolete()

              Mutable changeset with a newer version.

       origin([set])

              Changesets that were specified as a source for the grafts, transplants or rebases that created the
              given  revisions.  Omitting the optional set is the same as passing all().  If a changeset created
              by these operations is itself specified as a source for one of these operations, only  the  source
              changeset for the first operation is selected.

       outgoing([path])

              Changesets not found in the specified destination repository, or the default push location.

       p1([set])

              First parent of changesets in set, or the working directory.

       p2([set])

              Second parent of changesets in set, or the working directory.

       parents([set])

              The set of all parents for all changesets in set, or the working directory.

       present(set)

              An empty set, if any revision in set isn't found; otherwise, all revisions in set.

              If  any  of  specified  revisions  is  not  present in the local repository, the query is normally
              aborted. But this predicate allows the query to continue even in such cases.

       public()

              Changeset in public phase.

       remote([id [,path]])

              Local revision that corresponds to the given identifier in a remote repository, if present.  Here,
              the '.' identifier is a synonym for the current local branch.

       removes(pattern)

              Changesets which remove files matching pattern.

       rev(number)

              Revision with the given numeric identifier.

       reverse(set)

              Reverse order of set.

       roots(set)

              Changesets in set with no parent changeset in set.

       secret()

              Changeset in secret phase.

       sort(set[, [-]key...])

              Sort set by keys. The default sort order is ascending, specify a key as -key to sort in descending
              order.

              The keys can be:

              • rev for the revision number,

              • branch for the branch name,

              • desc for the commit message (description),

              • user for user name (author can be used as an alias),

              • date for the commit date

       tag([name])

              The specified tag by name, or all tagged revisions if no name is given.

       unstable()

              Non-obsolete changesets with obsolete ancestors.

       user(string)

              User name contains string. The match is case-insensitive.

              If  string  starts  with  re:,  the remainder of the string is treated as a regular expression. To
              match a user that actually contains re:, use the prefix literal:.

       New predicates (known as "aliases") can be defined, using any combination of existing predicates or other
       aliases. An alias definition looks like:

       <alias> = <definition>

       in the revsetalias section of a Mercurial configuration file. Arguments of the  form  $1,  $2,  etc.  are
       substituted from the alias into the definition.

       For example,

       [revsetalias]
       h = heads()
       d($1) = sort($1, date)
       rs($1, $2) = reverse(sort($1, $2))

       defines  three  aliases,  h,  d,  and  rs. rs(0:tip, author) is exactly equivalent to reverse(sort(0:tip,
       author)).

       Command line equivalents for hg log:

       -f    ->  ::.
       -d x  ->  date(x)
       -k x  ->  keyword(x)
       -m    ->  merge()
       -u x  ->  user(x)
       -b x  ->  branch(x)
       -P x  ->  !::x
       -l x  ->  limit(expr, x)

       Some sample queries:

       • Changesets on the default branch:

         hg log -r "branch(default)"

       • Changesets on the default branch since tag 1.5 (excluding merges):

         hg log -r "branch(default) and 1.5:: and not merge()"

       • Open branch heads:

         hg log -r "head() and not closed()"

       • Changesets between tags 1.3 and 1.5 mentioning "bug" that affect hgext/*:

         hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"

       • Changesets committed in May 2008, sorted by user:

         hg log -r "sort(date('May 2008'), user)"

       • Changesets mentioning "bug" or "issue" that are not in a tagged release:

         hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tag())"

SUBREPOSITORIES

       Subrepositories let you nest external repositories or projects into a parent  Mercurial  repository,  and
       make commands operate on them as a group.

       Mercurial currently supports Mercurial, Git, and Subversion subrepositories.

       Subrepositories are made of three components:

       1. Nested repository checkouts. They can appear anywhere in the parent working directory.

       2. Nested  repository  references.  They  are  defined  in  .hgsub, which should be placed in the root of
          working directory, and tell where the subrepository checkouts come from. Mercurial subrepositories are
          referenced like:

          path/to/nested = https://example.com/nested/repo/path

          Git and Subversion subrepos are also supported:

          path/to/nested = [git]git://example.com/nested/repo/path
          path/to/nested = [svn]https://example.com/nested/trunk/path

          where  path/to/nested  is  the  checkout  location  relatively  to  the  parent  Mercurial  root,  and
          https://example.com/nested/repo/path  is  the  source repository path. The source can also reference a
          filesystem path.

          Note that .hgsub does not exist by default in Mercurial repositories, you have to create and add it to
          the parent repository before using subrepositories.

       3. Nested repository states. They are defined in .hgsubstate, which is placed  in  the  root  of  working
          directory,  and  capture  whatever information is required to restore the subrepositories to the state
          they were committed in a parent  repository  changeset.  Mercurial  automatically  record  the  nested
          repositories states when committing in the parent repository.

       Note
          The .hgsubstate file should not be edited manually.

   Adding a Subrepository
       If  .hgsub  does not exist, create it and add it to the parent repository. Clone or checkout the external
       projects where you want it to live in the parent repository. Edit .hgsub and add the subrepository  entry
       as described above. At this point, the subrepository is tracked and the next commit will record its state
       in .hgsubstate and bind it to the committed changeset.

   Synchronizing a Subrepository
       Subrepos  do  not automatically track the latest changeset of their sources. Instead, they are updated to
       the changeset that corresponds with the changeset checked out in the  top-level  changeset.  This  is  so
       developers always get a consistent set of compatible code and libraries when they update.

       Thus,  updating  subrepos  is  a manual process. Simply check out target subrepo at the desired revision,
       test in the top-level repo, then commit in the parent repository to record the new combination.

   Deleting a Subrepository
       To remove a subrepository from the parent repository, delete its reference from .hgsub, then  remove  its
       files.

   Interaction with Mercurial Commands
       add    add  does  not recurse in subrepos unless -S/--subrepos is specified.  However, if you specify the
              full path of a file in a subrepo, it will be added even without -S/--subrepos specified.  Git  and
              Subversion subrepositories are currently silently ignored.

       archive
              archive does not recurse in subrepositories unless -S/--subrepos is specified.

       commit commit  creates  a consistent snapshot of the state of the entire project and its subrepositories.
              If any subrepositories have been modified, Mercurial will abort.  Mercurial can be made to instead
              commit   all    modified    subrepositories    by    specifying    -S/--subrepos,    or    setting
              "ui.commitsubrepos=True"  in a configuration file (see hg help config).  After there are no longer
              any modified subrepositories, it records  their  state  and  finally  commits  it  in  the  parent
              repository.

       diff   diff  does  not  recurse  in  subrepos unless -S/--subrepos is specified. Changes are displayed as
              usual, on the subrepositories elements. Git and Subversion subrepositories are currently  silently
              ignored.

       forget forget  currently only handles exact file matches in subrepos.  Git and Subversion subrepositories
              are currently silently ignored.

       incoming
              incoming does not recurse in subrepos  unless  -S/--subrepos  is  specified.  Git  and  Subversion
              subrepositories are currently silently ignored.

       outgoing
              outgoing  does  not  recurse  in  subrepos  unless  -S/--subrepos is specified. Git and Subversion
              subrepositories are currently silently ignored.

       pull   pull is not recursive since it is not clear what to pull prior to running hg update.  Listing  and
              retrieving  all  subrepositories  changes referenced by the parent repository pulled changesets is
              expensive at best, impossible in the Subversion case.

       push   Mercurial will automatically push all subrepositories first when the parent  repository  is  being
              pushed.  This  ensures  new  subrepository  changes  are  available  when  referenced by top-level
              repositories.  Push is a no-op for Subversion subrepositories.

       status status does not recurse into subrepositories  unless  -S/--subrepos  is  specified.  Subrepository
              changes  are  displayed  as  regular  Mercurial  changes on the subrepository elements. Subversion
              subrepositories are currently silently ignored.

       update update restores the subrepos in the state they were originally committed in target  changeset.  If
              the  recorded  changeset  is not available in the current subrepository, Mercurial will pull it in
              first  before  updating.   This  means  that  updating  can  require  network  access  when  using
              subrepositories.

   Remapping Subrepositories Sources
       A  subrepository  source location may change during a project life, invalidating references stored in the
       parent repository history. To fix this, rewriting rules can be defined in parent repository hgrc file  or
       in Mercurial configuration. See the [subpaths] section in hgrc(5) for more details.

TEMPLATE USAGE

       Mercurial allows you to customize output of commands through templates. You can either pass in a template
       from the command line, via the --template option, or select an existing template-style (--style).

       You  can  customize  output  for any "log-like" command: log, outgoing, incoming, tip, parents, heads and
       glog.

       Five styles are packaged with Mercurial: default (the style used when no explicit preference is  passed),
       compact, changelog, phases and xml.  Usage:

       $ hg log -r1 --style changelog

       A template is a piece of text, with markup to invoke variable expansion:

       $ hg log -r1 --template "{node}\n"
       b56ce7b07c52de7d5fd79fb89701ea538af65746

       Strings in curly braces are called keywords. The availability of keywords depends on the exact context of
       the templater. These keywords are usually available for templating a log-like command:

       author String. The unmodified author of the changeset.

       bisect String. The changeset bisection status.

       bookmarks
              List of strings. Any bookmarks associated with the changeset.

       branch String. The name of the branch on which the changeset was committed.

       branches
              List of strings. The name of the branch on which the changeset was committed. Will be empty if the
              branch name was default.

       children
              List of strings. The children of the changeset.

       date   Date information. The date when the changeset was committed.

       desc   String. The text of the changeset description.

       diffstat
              String. Statistics of changes with the following format: "modified files: +added/-removed lines"

       file_adds
              List of strings. Files added by this changeset.

       file_copies
              List of strings. Files copied in this changeset with their sources.

       file_copies_switch
              List of strings. Like "file_copies" but displayed only if the --copied switch is set.

       file_dels
              List of strings. Files removed by this changeset.

       file_mods
              List of strings. Files modified by this changeset.

       files  List of strings. All files modified, added, or removed by this changeset.

       latesttag
              String. Most recent global tag in the ancestors of this changeset.

       latesttagdistance
              Integer. Longest path to the latest tag.

       node   String. The changeset identification hash, as a 40 hexadecimal digit string.

       p1node String. The identification hash of the changeset's first parent, as a 40 digit hexadecimal string.
              If the changeset has no parents, all digits are 0.

       p1rev  Integer.  The  repository-local  revision  number  of  the  changeset's first parent, or -1 if the
              changeset has no parents.

       p2node String. The identification hash of the changeset's  second  parent,  as  a  40  digit  hexadecimal
              string. If the changeset has no second parent, all digits are 0.

       p2rev  Integer.  The  repository-local  revision  number  of  the changeset's second parent, or -1 if the
              changeset has no second parent.

       parents
              List of strings. The parents of the changeset in "rev:node" format. If the changeset has only  one
              "natural" parent (the predecessor revision) nothing is shown.

       phase  String. The changeset phase name.

       phaseidx
              Integer. The changeset phase index.

       rev    Integer. The repository-local changeset revision number.

       tags   List of strings. Any tags associated with the changeset.

       The  "date" keyword does not produce human-readable output. If you want to use a date in your output, you
       can use a filter to process it. Filters are functions which return a string based on the input  variable.
       Be sure to use the stringify filter first when you're applying a string-input filter to a list-like input
       variable.  You can also use a chain of filters to get the desired output:

       $ hg tip --template "{date|isodate}\n"
       2008-08-21 18:22 +0000

       List of filters:

       addbreaks
              Any text. Add an XHTML "<br />" tag before the end of every line except the last.

       age    Date.  Returns  a  human-readable date/time difference between the given date/time and the current
              date/time.

       basename
              Any text. Treats the text as a path, and returns the last component of the path after splitting by
              the path separator (ignoring trailing separators). For example, "foo/bar/baz"  becomes  "baz"  and
              "foo/bar//" becomes "bar".

       date   Date.  Returns  a  date  in  a Unix date format, including the timezone: "Mon Sep 04 15:13:13 2006
              0700".

       domain Any text. Finds the first string that looks like an email address, and extracts  just  the  domain
              component. Example: User <user@example.com> becomes example.com.

       email  Any   text.   Extracts  the  first  string  that  looks  like  an  email  address.  Example:  User
              <user@example.com> becomes user@example.com.

       emailuser
              Any text. Returns the user portion of an email address.

       escape Any text. Replaces the special XML/XHTML characters "&",  "<"  and  ">"  with  XML  entities,  and
              filters out NUL characters.

       fill68 Any text. Wraps the text to fit in 68 columns.

       fill76 Any text. Wraps the text to fit in 76 columns.

       firstline
              Any text. Returns the first line of text.

       hex    Any text. Convert a binary Mercurial node identifier into its long hexadecimal representation.

       hgdate Date. Returns the date as a pair of numbers: "1157407993 25200" (Unix timestamp, timezone offset).

       isodate
              Date. Returns the date in ISO 8601 format: "2009-08-18 13:00 +0200".

       isodatesec
              Date.  Returns  the  date  in ISO 8601 format, including seconds: "2009-08-18 13:00:13 +0200". See
              also the rfc3339date filter.

       localdate
              Date. Converts a date to local date.

       nonempty
              Any text. Returns '(none)' if the string is empty.

       obfuscate
              Any text. Returns the input text rendered as a sequence of XML entities.

       person Any text. Returns the name before an email address, interpreting it as per RFC 5322.

       rfc3339date
              Date.   Returns   a   date   using   the   Internet   date   format   specified   in   RFC   3339:
              "2009-08-18T13:00:13+02:00".

       rfc822date
              Date.  Returns  a  date  using  the  same format used in email headers: "Tue, 18 Aug 2009 13:00:13
              +0200".

       short  Changeset hash. Returns the short form of a changeset hash, i.e. a 12 hexadecimal digit string.

       shortbisect
              Any text. Treats text as a bisection status,  and  returns  a  single-character  representing  the
              status (G: good, B: bad, S: skipped, U: untested, I: ignored). Returns single space if text is not
              a valid bisection status.

       shortdate
              Date. Returns a date like "2006-09-18".

       stringify
              Any type. Turns the value into text by converting values into text and concatenating them.

       strip  Any text. Strips all leading and trailing whitespace.

       stripdir
              Treat  the text as path and strip a directory level, if possible. For example, "foo" and "foo/bar"
              becomes "foo".

       tabindent
              Any text. Returns the text, with every non-empty  line  except  the  first  starting  with  a  tab
              character.

       urlescape
              Any text. Escapes all "special" characters. For example, "foo bar" becomes "foo%20bar".

       user   Any text. Returns a short representation of a user name or email address.

       Note that a filter is nothing more than a function call, i.e.  expr|filter is equivalent to filter(expr).

       In addition to filters, there are some basic built-in functions:

       • date(date[, fmt])

       • fill(text[, width])

       • get(dict, key)

       • if(expr, then[, else])

       • ifeq(expr, expr, then[, else])

       • join(list, sep)

       • label(label, expr)

       • rstdoc(text, style)

       • strip(text[, chars])

       • sub(pat, repl, expr)

       Also, for any expression that returns a list, there is a list operator:

       • expr % "{template}"

       Some sample command line templates:

       • Format lists, e.g. files:

         $ hg log -r 0 --template "files:\n{files % '  {file}\n'}"

       • Join the list of files with a ", ":

         $ hg log -r 0 --template "files: {join(files, ', ')}\n"

       • Format date:

         $ hg log -r 0 --template "{date(date, '%Y')}\n"

       • Output the description set to a fill-width of 30:

         $ hg log -r 0 --template "{fill(desc, '30')}"

       • Use a conditional to test for the default branch:

         $ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch',
         'on branch {branch}')}\n"

       • Append a newline if not empty:

         $ hg tip --template "{if(author, '{author}\n')}"

       • Label the output for use with the color extension:

         $ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n"

       • Invert the firstline filter, i.e. everything but the first line:

         $ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n"

URL PATHS

       Valid URLs are of the form:

       local/filesystem/path[#revision]
       file://local/filesystem/path[#revision]
       http://[user[:pass]@]host[:port]/[path][#revision]
       https://[user[:pass]@]host[:port]/[path][#revision]
       ssh://[user@]host[:port]/[path][#revision]

       Paths  in  the local filesystem can either point to Mercurial repositories or to bundle files (as created
       by hg bundle or hg incoming --bundle). See also hg help paths.

       An optional identifier after # indicates a particular branch, tag, or changeset to use  from  the  remote
       repository. See also hg help revisions.

       Some  features,  such  as  pushing  to  http:// and  https:// URLs  are  only  possible if the feature is
       explicitly enabled on the remote Mercurial server.

       Note that the security of HTTPS URLs depends on proper configuration of web.cacerts.

       Some notes about using SSH with Mercurial:

       • SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path
         or specified with as remotecmd.

       • path is relative to the remote user's home directory by default. Use an extra slash at the start  of  a
         path to specify an absolute path:

         ssh://example.com//tmp/repository

       • Mercurial  doesn't  use  its  own compression via SSH; the right thing to do is to configure it in your
         ~/.ssh/config, e.g.:

         Host *.mylocalnetwork.example.com
           Compression no
         Host *
           Compression yes

         Alternatively specify "ssh -C" as your ssh command in your configuration file or with the --ssh command
         line option.

       These URLs can all be stored in your configuration file with path aliases under the [paths] section  like
       so:

       [paths]
       alias1 = URL1
       alias2 = URL2
       ...

       You can then use the alias for any command that uses a URL (for example hg pull alias1 will be treated as
       hg pull URL1).

       Two  path  aliases  are  special  because  they are used as defaults when you do not provide the URL to a
       command:

       default:
              When you create a repository with hg clone, the clone command saves the  location  of  the  source
              repository as the new repository's 'default' path. This is then used when you omit path from push-
              and pull-like commands (including incoming and outgoing).

       default-push:
              The  push  command will look for a path named 'default-push', and prefer it over 'default' if both
              are defined.

EXTENSIONS

       This section contains help for extensions that are distributed together with Mercurial.  Help  for  other
       extensions is available in the help system.

   acl
       hooks for controlling repository access

       This  hook  makes  it  possible to allow or deny write access to given branches and paths of a repository
       when receiving incoming changesets via pretxnchangegroup and pretxncommit.

       The authorization is matched based on the local user name on the system where the hook runs, and not  the
       committer of the original changeset (since the latter is merely informative).

       The  acl  hook is best used along with a restricted shell like hgsh, preventing authenticating users from
       doing anything other than pushing or pulling. The hook is not safe to use if users have interactive shell
       access, as they can then disable the hook. Nor is it safe if remote users share an account, because  then
       there is no way to distinguish them.

       The order in which access checks are performed is:

       1. Deny  list for branches (section acl.deny.branches)

       2. Allow list for branches (section acl.allow.branches)

       3. Deny  list for paths    (section acl.deny)

       4. Allow list for paths    (section acl.allow)

       The allow and deny sections take key-value pairs.

   Branch-based Access Control
       Use  the  acl.deny.branches  and acl.allow.branches sections to have branch-based access control. Keys in
       these sections can be either:

       • a branch name, or

       • an asterisk, to match any branch;

       The corresponding values can be either:

       • a comma-separated list containing users and groups, or

       • an asterisk, to match anyone;

       You can add the "!" prefix to a user or group name to invert the sense of the match.

   Path-based Access Control
       Use the acl.deny and acl.allow sections to have path-based access control. Keys in these sections  accept
       a subtree pattern (with a glob syntax by default). The corresponding values follow the same syntax as the
       other sections above.

   Groups
       Group  names must be prefixed with an @ symbol. Specifying a group name has the same effect as specifying
       all the users in that group.

       You can define group members in the acl.groups section.  If a  group  name  is  not  defined  there,  and
       Mercurial  is  running under a Unix-like system, the list of users will be taken from the OS.  Otherwise,
       an exception will be raised.

   Example Configuration
       [hooks]

       # Use this if you want to check access restrictions at commit time
       pretxncommit.acl = python:hgext.acl.hook

       # Use this if you want to check access restrictions for pull, push,
       # bundle and serve.
       pretxnchangegroup.acl = python:hgext.acl.hook

       [acl]
       # Allow or deny access for incoming changes only if their source is
       # listed here, let them pass otherwise. Source is "serve" for all
       # remote access (http or ssh), "push", "pull" or "bundle" when the
       # related commands are run locally.
       # Default: serve
       sources = serve

       [acl.deny.branches]

       # Everyone is denied to the frozen branch:
       frozen-branch = *

       # A bad user is denied on all branches:
       * = bad-user

       [acl.allow.branches]

       # A few users are allowed on branch-a:
       branch-a = user-1, user-2, user-3

       # Only one user is allowed on branch-b:
       branch-b = user-1

       # The super user is allowed on any branch:
       * = super-user

       # Everyone is allowed on branch-for-tests:
       branch-for-tests = *

       [acl.deny]
       # This list is checked first. If a match is found, acl.allow is not
       # checked. All users are granted access if acl.deny is not present.
       # Format for both lists: glob pattern = user, ..., @group, ...

       # To match everyone, use an asterisk for the user:
       # my/glob/pattern = *

       # user6 will not have write access to any file:
       ** = user6

       # Group "hg-denied" will not have write access to any file:
       ** = @hg-denied

       # Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
       # everyone being able to change all other files. See below.
       src/main/resources/DONT-TOUCH-THIS.txt = *

       [acl.allow]
       # if acl.allow is not present, all users are allowed by default
       # empty acl.allow = no users allowed

       # User "doc_writer" has write access to any file under the "docs"
       # folder:
       docs/** = doc_writer

       # User "jack" and group "designers" have write access to any file
       # under the "images" folder:
       images/** = jack, @designers

       # Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
       # will have write access to any file under the "resources" folder
       # (except for 1 file. See acl.deny):
       src/main/resources/** = *

       .hgtags = release_engineer

   Examples using the ! prefix
       Suppose there's a branch that only a given user (or group) should be able to push to, and you don't  want
       to restrict access to any other branch that may be created.

       The  "!"  prefix  allows you to prevent anyone except a given user or group to push changesets in a given
       branch or path.

       In the examples below, we will: 1) Deny access to branch "ring" to  anyone  but  user  "gollum"  2)  Deny
       access  to  branch  "lake" to anyone but members of the group "hobbit" 3) Deny access to a file to anyone
       but user "gollum"

       [acl.allow.branches]
       # Empty

       [acl.deny.branches]

       # 1) only 'gollum' can commit to branch 'ring';
       # 'gollum' and anyone else can still commit to any other branch.
       ring = !gollum

       # 2) only members of the group 'hobbit' can commit to branch 'lake';
       # 'hobbit' members and anyone else can still commit to any other branch.
       lake = !@hobbit

       # You can also deny access based on file paths:

       [acl.allow]
       # Empty

       [acl.deny]
       # 3) only 'gollum' can change the file below;
       # 'gollum' and anyone else can still change any other file.
       /misty/mountains/cave/ring = !gollum

   blackbox
       log repository events to a blackbox for debugging

       Logs event information to .hg/blackbox.log to help debug and diagnose  problems.   The  events  that  get
       logged can be configured via the blackbox.track config key.  Examples:

       [blackbox]
       track = *

       [blackbox]
       track = command, commandfinish, commandexception, exthook, pythonhook

       [blackbox]
       track = incoming

       [blackbox]
       # limit the size of a log file
       maxsize = 1.5 MB
       # rotate up to N log files when the current one gets too big
       maxfiles = 3

   Commands
   blackbox
       hg blackbox [OPTION]...

       view the recent repository events

       Options:

       -l, --limit
              the number of events to show (default: 10)

   bugzilla
       hooks for integrating with the Bugzilla bug tracker

       This  hook  extension adds comments on bugs in Bugzilla when changesets that refer to bugs by Bugzilla ID
       are seen. The comment is formatted using the Mercurial template mechanism.

       The bug references can optionally include an update for Bugzilla of the hours spent working on  the  bug.
       Bugs can also be marked fixed.

       Three basic modes of access to Bugzilla are provided:

       1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.

       2. Check  data  via  the  Bugzilla  XMLRPC  interface  and  submit bug change via email to Bugzilla email
          interface. Requires Bugzilla 3.4 or later.

       3. Writing directly to the Bugzilla database. Only Bugzilla  installations  using  MySQL  are  supported.
          Requires Python MySQLdb.

       Writing  directly  to  the  database  is  susceptible to schema changes, and relies on a Bugzilla contrib
       script to send out bug change notification emails. This script runs as the user running  Mercurial,  must
       be  run  on  the  host  with the Bugzilla install, and requires permission to read Bugzilla configuration
       details and the necessary MySQL user and password to have full access rights to  the  Bugzilla  database.
       For these reasons this access mode is now considered deprecated, and will not be updated for new Bugzilla
       versions going forward. Only adding comments is supported in this access mode.

       Access  via  XMLRPC needs a Bugzilla username and password to be specified in the configuration. Comments
       are added under that username. Since the configuration must be readable by all  Mercurial  users,  it  is
       recommended  that  the  rights  of  that  user are restricted in Bugzilla to the minimum necessary to add
       comments. Marking bugs fixed requires Bugzilla 4.0 and later.

       Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends email to the Bugzilla email interface to
       submit comments to bugs.  The From: address in the email is set to the email  address  of  the  Mercurial
       user,  so the comment appears to come from the Mercurial user. In the event that the Mercurial user email
       is not recognized by Bugzilla as a Bugzilla user, the email associated with the Bugzilla username used to
       log into Bugzilla is used instead as the source of the comment. Marking bugs fixed works on all supported
       Bugzilla versions.

       Configuration items common to all access modes:

       bugzilla.version
              The access type to use. Values recognized are:

              xmlrpc

                     Bugzilla XMLRPC interface.

              xmlrpc+email

       bugzilla.regexp
              Regular expression to match bug IDs for update in changeset commit message.  It must  contain  one
              "()"  named  group  <ids>  containing  the  bug IDs separated by non-digit characters. It may also
              contain a named group <hours> with a floating-point number giving the hours worked on the bug.  If
              no named groups are present, the first "()" group is assumed to contain the bug IDs, and work time
              is  not  updated.  The  default  expression  matches Bug 1234, Bug no. 1234, Bug number 1234, Bugs
              1234,5678, Bug 1234 and 5678 and variations thereof, followed by an hours number prefixed by h  or
              hours, e.g. hours 1.5. Matching is case insensitive.

       bugzilla.fixregexp
              Regular  expression  to  match  bug  IDs  for marking fixed in changeset commit message. This must
              contain a "()" named group <ids>` containing the bug IDs separated by non-digit characters. It may
              also contain a named group ``<hours> with a floating-point number giving the hours worked  on  the
              bug.  If  no named groups are present, the first "()" group is assumed to contain the bug IDs, and
              work time is not updated. The default expression matches Fixes 1234, Fixes bug  1234,  Fixes  bugs
              1234,5678,  Fixes  1234 and 5678 and variations thereof, followed by an hours number prefixed by h
              or hours, e.g. hours 1.5. Matching is case insensitive.

       bugzilla.fixstatus
              The status to set a bug to when marking fixed. Default RESOLVED.

       bugzilla.fixresolution
              The resolution to set a bug to when marking fixed. Default FIXED.

       bugzilla.style
              The style file to use when formatting comments.

       bugzilla.template
              Template to use when formatting comments. Overrides style if specified. In addition to  the  usual
              Mercurial keywords, the extension specifies:

              {bug}

                     The Bugzilla bug ID.

              {root}

                     The full pathname of the Mercurial repository.

              {webroot}

                     Stripped pathname of the Mercurial repository.

              {hgweb}

                     Base URL for browsing Mercurial repositories.

              Default changeset {node|short} in repo {root} refers to bug {bug}.\ndetails:\n\t{desc|tabindent}

       bugzilla.strip
              The  number  of path separator characters to strip from the front of the Mercurial repository path
              ({root}  in  templates)  to  produce  {webroot}.   For   example,   a   repository   with   {root}
              /var/local/my-project with a strip of 2 gives a value for {webroot} of my-project. Default 0.

       web.baseurl
              Base URL for browsing Mercurial repositories. Referenced from templates as {hgweb}.

       Configuration items common to XMLRPC+email and MySQL access modes:

       bugzilla.usermap
              Path  of  file containing Mercurial committer email to Bugzilla user email mappings. If specified,
              the file should contain one mapping per line:

              committer = Bugzilla user

              See also the [usermap] section.

       The [usermap] section is used to specify mappings of Mercurial committer email to  Bugzilla  user  email.
       See also bugzilla.usermap.  Contains entries of the form committer = Bugzilla user.

       XMLRPC access mode configuration:

       bugzilla.bzurl
              The base URL for the Bugzilla installation.  Default http://localhost/bugzilla.

              The username to use to log into Bugzilla via XMLRPC. Default bugs.

       bugzilla.password
              The password for Bugzilla login.

       XMLRPC+email access mode uses the XMLRPC access mode configuration items, and also:

       bugzilla.bzemail
              The Bugzilla email address.

       In  addition, the Mercurial email settings must be configured. See the documentation in hgrc(5), sections
       [email] and [smtp].

       MySQL access mode configuration:

       bugzilla.host
              Hostname of the MySQL server holding the Bugzilla database.  Default localhost.

       bugzilla.password
              Password to use to access MySQL server.

       bugzilla.timeout
              Database connection timeout (seconds). Default 5.

       bugzilla.bzuser
              Fallback Bugzilla user name to record comments with, if changeset committer cannot be found  as  a
              Bugzilla user.

       bugzilla.bzdir
              Bugzilla install directory. Used by default notify. Default /var/www/html/bugzilla.

       bugzilla.notify
              The  command to run to get Bugzilla to send bug change notification emails. Substitutes from a map
              with 3 keys, bzdir, id (bug id) and user (committer bugzilla email). Default depends  on  version;
              from 2.18 it is "cd %(bzdir)s && perl -T contrib/sendbugmail.pl %(id)s %(user)s".

       Changeset commit comment. Bug 1234.

   children
       command to display child changesets (DEPRECATED)

       This extension is deprecated. You should use hg log -r "children(REV)" instead.

   Commands
   children
       hg children [-r REV] [FILE]

       Print the children of the working directory's revisions.  If  a  revision  is  given  via  -r/--rev,  the
       children  of  that  revision will be printed. If a file argument is given, revision in which the file was
       last changed (after the working directory revision or the argument to --rev if given) is printed.

       Options:

       -r, --rev
              show children of the specified revision

       --style
              display using template map file

       --template
              display with template

   churn
       command to display statistics about repository history

   Commands
   churn
       hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]

       This command will display a histogram representing the number of  changed  lines  or  revisions,  grouped
       according  to  the  given  template. The default template will group changes by author.  The --dateformat
       option may be used to group the results by date instead.

       Statistics are based on the number of changed lines, or alternatively the number of matching revisions if
       the --changesets option is specified.

       Examples:

       # display count of changed lines for every committer
       hg churn -t "{author|email}"

       # display daily activity graph
       hg churn -f "%H" -s -c

       # display activity of developers by month
       hg churn -f "%Y-%m" -s -c

       # display count of lines changed in every year
       hg churn -f "%Y" -s

       It is possible to map alternate email addresses to a main address by providing a file using the following
       format:

       <alias email> = <actual email>

       Such a file may be specified with the --aliases option, otherwise a .hgchurn file will be looked  for  in
       the working directory root.  Aliases will be split from the rightmost "=".

       Options:

       -r, --rev
              count rate for the specified revision or range

       -d, --date
              count rate for revisions matching date spec

       -t, --template
              template to group changesets (default: {author|email})

       -f, --dateformat
              strftime-compatible format for grouping by date

       -c, --changesets
              count rate by number of changesets

       -s, --sort
              sort by key (default: sort by count)

       --diffstat
              display added/removed lines separately

       --aliases
              file with email aliases

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   color
       colorize output from some commands

       This  extension  modifies  the  status  and resolve commands to add color to their output to reflect file
       status, the qseries command to add color to reflect patch status (applied, unapplied,  missing),  and  to
       diff-related commands to highlight additions, removals, diff headers, and trailing whitespace.

       Other  effects  in  addition to color, like bold and underlined text, are also available. By default, the
       terminfo database is used to find the terminal codes used to change color and effect.  If terminfo is not
       available, then effects are rendered with the ECMA-48 SGR control function (aka ANSI escape codes).

       Default effects may be overridden from your configuration file:

       [color]
       status.modified = blue bold underline red_background
       status.added = green bold
       status.removed = red bold blue_background
       status.deleted = cyan bold underline
       status.unknown = magenta bold underline
       status.ignored = black bold

       # 'none' turns off all effects
       status.clean = none
       status.copied = none

       qseries.applied = blue bold underline
       qseries.unapplied = black bold
       qseries.missing = red bold

       diff.diffline = bold
       diff.extended = cyan bold
       diff.file_a = red bold
       diff.file_b = green bold
       diff.hunk = magenta
       diff.deleted = red
       diff.inserted = green
       diff.changed = white
       diff.trailingwhitespace = bold red_background

       resolve.unresolved = red bold
       resolve.resolved = green bold

       bookmarks.current = green

       branches.active = none
       branches.closed = black bold
       branches.current = green
       branches.inactive = none

       tags.normal = green
       tags.local = black bold

       rebase.rebased = blue
       rebase.remaining = red bold

       shelve.age = cyan
       shelve.newest = green bold
       shelve.name = blue bold

       histedit.remaining = red bold

       The available effects in terminfo mode are 'blink',  'bold',  'dim',  'inverse',  'invisible',  'italic',
       'standout',  and  'underline';  in  ECMA-48  mode,  the  options  are  'bold',  'inverse',  'italic', and
       'underline'.  How each is rendered depends on the terminal emulator.  Some may not  be  available  for  a
       given terminal type, and will be silently ignored.

       Note that on some systems, terminfo mode may cause problems when using color with the pager extension and
       less  -R.  less with the -R option will only display ECMA-48 color codes, and terminfo mode may sometimes
       emit codes that less doesn't understand. You can work around this by either  using  ansi  mode  (or  auto
       mode),  or  by  using less -r (which will pass through all terminal control codes, not just color control
       codes).

       Because there are only eight standard colors, this module allows you to  define  color  names  for  other
       color slots which might be available for your terminal type, assuming terminfo mode.  For instance:

       color.brightblue = 12
       color.pink = 207
       color.orange = 202

       to  set 'brightblue' to color slot 12 (useful for 16 color terminals that have brighter colors defined in
       the upper eight) and, 'pink' and 'orange' to colors in  256-color  xterm's  default  color  cube.   These
       defined colors may then be used as any of the pre-defined eight, including appending '_background' to set
       the background to that color.

       By  default,  the color extension will use ANSI mode (or win32 mode on Windows) if it detects a terminal.
       To override auto mode (to enable terminfo mode, for example), set the following configuration option:

       [color]
       mode = terminfo

       Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will disable color.

   convert
       import revisions from foreign VCS repositories into Mercurial

   Commands
   convert
       hg convert [OPTION]... SOURCE [DEST [REVMAP]]

       Accepted source formats [identifiers]:

       • Mercurial [hg]

       • CVS [cvs]

       • Darcs [darcs]

       • git [git]

       • Subversion [svn]

       • Monotone [mtn]

       • GNU Arch [gnuarch]

       • Bazaar [bzr]

       • Perforce [p4]

       Accepted destination formats [identifiers]:

       • Mercurial [hg]

       • Subversion [svn] (history on branches is not preserved)

       If no revision is given, all revisions will be converted.  Otherwise, convert will only import up to  the
       named revision (given in a format understood by the source).

       If  no  destination  directory  name  is  specified,  it  defaults to the basename of the source with -hg
       appended. If the destination repository doesn't exist, it will be created.

       By default, all sources except Mercurial will use --branchsort.  Mercurial uses --sourcesort to  preserve
       original revision numbers order. Sort modes have the following effects:

       --branchsort
              convert  from  parent  to child revision when possible, which means branches are usually converted
              one after the other. It generates more compact repositories.

       --datesort
              sort revisions by date. Converted repositories have good-looking changelogs but are often an order
              of magnitude larger than the same ones generated by --branchsort.

       --sourcesort
              try to preserve source revisions order, only supported by Mercurial sources.

       --closesort
              try to move closed revisions as close as possible to parent branches, only supported by  Mercurial
              sources.

       If REVMAP isn't given, it will be put in a default location (<dest>/.hg/shamap by default). The REVMAP is
       a simple text file that maps each source commit ID to the destination ID for that revision, like so:

       <source ID> <destination ID>

       If  the file doesn't exist, it's automatically created. It's updated on each commit copied, so hg convert
       can be interrupted and can be run repeatedly to copy new commits.

       The authormap is a simple text file that maps each source commit author to a destination  commit  author.
       It  is  handy  for  source SCMs that use unix logins to identify authors (e.g.: CVS). One line per author
       mapping and the line format is:

       source author = destination author

       Empty lines and lines starting with a # are ignored.

       The filemap is a file that allows filtering and remapping of files and directories. Each line can contain
       one of the following directives:

       include path/to/file-or-dir

       exclude path/to/file-or-dir

       rename path/to/source path/to/destination

       Comment lines start with #. A specified path matches if it equals the full relative name of a file or one
       of its parent directories. The include or exclude directive with the longest matching  path  applies,  so
       line order does not matter.

       The  include  directive  causes a file, or all files under a directory, to be included in the destination
       repository, and the exclusion of all other files and directories not  explicitly  included.  The  exclude
       directive  causes files or directories to be omitted. The rename directive renames a file or directory if
       it is converted. To rename from a subdirectory into the root of the repository, use  .  as  the  path  to
       rename to.

       The  splicemap is a file that allows insertion of synthetic history, letting you specify the parents of a
       revision. This is useful if you want  to  e.g.  give  a  Subversion  merge  two  parents,  or  graft  two
       disconnected  series of history together. Each entry contains a key, followed by a space, followed by one
       or two comma-separated values:

       key parent1, parent2

       The key is the revision ID in the source revision control system whose parents should be  modified  (same
       format  as  a  key  in  .hg/shamap). The values are the revision IDs (in either the source or destination
       revision control system) that should be used as the new parents for that node. For example, if  you  have
       merged  "release-1.0"  into  "trunk", then you should specify the revision on "trunk" as the first parent
       and the one on the "release-1.0" branch as the second.

       The branchmap is a file that allows you to rename a branch when it is  being  brought  in  from  whatever
       external  repository.  When used in conjunction with a splicemap, it allows for a powerful combination to
       help fix even the most badly mismanaged repositories and  turn  them  into  nicely  structured  Mercurial
       repositories. The branchmap contains lines of the form:

       original_branch_name new_branch_name

       where "original_branch_name" is the name of the branch in the source repository, and "new_branch_name" is
       the  name of the branch is the destination repository. No whitespace is allowed in the branch names. This
       can be used to (for instance) move code in one repository from "default" to a named branch.

   Mercurial Source
       The Mercurial source recognizes the following configuration options, which you can  set  on  the  command
       line with --config:

       convert.hg.ignoreerrors
              ignore  integrity errors when reading.  Use it to fix Mercurial repositories with missing revlogs,
              by converting from and to Mercurial. Default is False.

       convert.hg.saverev
              store original revision ID in changeset (forces target IDs to change). It takes a boolean argument
              and defaults to False.

       convert.hg.revs
              revset specifying the source revisions to convert.

   CVS Source
       CVS source will use a sandbox (i.e. a checked-out copy) from CVS to indicate the starting point  of  what
       will  be  converted. Direct access to the repository files is not needed, unless of course the repository
       is :local:. The conversion uses the top level directory in the sandbox to find the  CVS  repository,  and
       then  uses  CVS  rlog  commands  to find files to convert. This means that unless a filemap is given, all
       files under the starting directory will be converted, and that any directory reorganization  in  the  CVS
       sandbox is ignored.

       The following options can be used with --config:

       convert.cvsps.cache
              Set to False to disable remote log caching, for testing and debugging purposes. Default is True.

       convert.cvsps.fuzz
              Specify  the maximum time (in seconds) that is allowed between commits with identical user and log
              message in a single changeset. When very large files were checked in as part of a  changeset  then
              the default may not be long enough.  The default is 60.

       convert.cvsps.mergeto
              Specify a regular expression to which commit log messages are matched. If a match occurs, then the
              conversion  process  will  insert  a  dummy  revision merging the branch on which this log message
              occurs to the branch indicated in the regex. Default is {{mergetobranch ([-\w]+)}}

       convert.cvsps.mergefrom
              Specify a regular expression to which commit log messages are matched. If a match occurs, then the
              conversion process will add the most recent revision on the branch indicated in the regex  as  the
              second parent of the changeset. Default is {{mergefrombranch ([-\w]+)}}

       convert.localtimezone
              use  local  time  (as  determined  by  the  TZ environment variable) for changeset date/times. The
              default is False (use UTC).

       hooks.cvslog
              Specify a Python function to be called at the end of gathering the CVS log. The function is passed
              a list with the log entries, and can modify the entries in-place, or add or delete them.

       hooks.cvschangesets
              Specify a Python function to be called after the changesets are calculated from the CVS  log.  The
              function  is  passed a list with the changeset entries, and can modify the changesets in-place, or
              add or delete them.

       An additional "debugcvsps" Mercurial command allows the builtin changeset merging code to be run  without
       doing  a  conversion.  Its parameters and output are similar to that of cvsps 2.1. Please see the command
       help for more details.

   Subversion Source
       Subversion  source  detects  classical   trunk/branches/tags   layouts.    By   default,   the   supplied
       svn://repo/path/  source URL is converted as a single branch. If svn://repo/path/trunk exists it replaces
       the default branch. If  svn://repo/path/branches  exists,  its  subdirectories  are  listed  as  possible
       branches.  If  svn://repo/path/tags exists, it is looked for tags referencing converted branches. Default
       trunk, branches and tags values can be overridden with following options. Set them to paths  relative  to
       the source URL, or leave them blank to disable auto detection.

       The following options can be set with --config:

       convert.svn.branches
              specify the directory containing branches.  The default is branches.

       convert.svn.tags
              specify the directory containing tags. The default is tags.

       convert.svn.trunk
              specify the name of the trunk branch. The default is trunk.

       convert.localtimezone
              use  local  time  (as  determined  by  the  TZ environment variable) for changeset date/times. The
              default is False (use UTC).

       Source history can be retrieved starting at a specific revision, instead of being  integrally  converted.
       Only single branch conversions are supported.

       convert.svn.startrev
              specify start Subversion revision number.  The default is 0.

   Perforce Source
       The  Perforce  (P4)  importer  can  be given a p4 depot path or a client specification as source. It will
       convert all files  in  the  source  to  a  flat  Mercurial  repository,  ignoring  labels,  branches  and
       integrations.  Note  that  when a depot path is given you then usually should specify a target directory,
       because otherwise the target may be named ...-hg.

       It is possible to limit the amount of source history to be converted by specifying  an  initial  Perforce
       revision:

       convert.p4.startrev
              specify initial Perforce revision (a Perforce changelist number).

   Mercurial Destination
       The following options are supported:

       convert.hg.clonebranches
              dispatch source branches in separate clones. The default is False.

       convert.hg.tagsbranch
              branch name for tag revisions, defaults to default.

       convert.hg.usebranchnames
              preserve branch names. The default is True.

       Options:

       --authors
              username mapping filename (DEPRECATED, use --authormap instead)

       -s, --source-type
              source repository type

       -d, --dest-type
              destination repository type

       -r, --rev
              import up to source revision REV

       -A, --authormap
              remap usernames using this file

       --filemap
              remap file names using contents of file

       --splicemap
              splice synthesized history into place

       --branchmap
              change branch names while converting

       --branchsort
              try to sort changesets by branches

       --datesort
              try to sort changesets by date

       --sourcesort
              preserve source changesets order

       --closesort
              try to reorder closed revisions

   eol
       automatically manage newlines in repository files

       This extension allows you to manage the type of line endings (CRLF or LF) that are used in the repository
       and in the local working directory. That way you can get CRLF line endings on Windows and LF on Unix/Mac,
       thereby letting everybody use their OS native line endings.

       The extension reads its configuration from a versioned .hgeol configuration file found in the root of the
       working copy. The .hgeol file use the same syntax as all other Mercurial configuration files. It uses two
       sections, [patterns] and [repository].

       The  [patterns]  section  specifies how line endings should be converted between the working copy and the
       repository. The format is specified by a file pattern. The first match is  used,  so  put  more  specific
       patterns first. The available line endings are LF, CRLF, and BIN.

       Files  with the declared format of CRLF or LF are always checked out and stored in the repository in that
       format and files declared to be binary (BIN) are left unchanged. Additionally, native  is  an  alias  for
       checking  out in the platform's default line ending: LF on Unix (including Mac OS X) and CRLF on Windows.
       Note that BIN (do nothing to line endings) is Mercurial's default behaviour; it is  only  needed  if  you
       need to override a later, more general pattern.

       The  optional  [repository] section specifies the line endings to use for files stored in the repository.
       It has a single setting, native, which determines the storage line endings for files declared  as  native
       in  the  [patterns] section. It can be set to LF or CRLF. The default is LF. For example, this means that
       on Windows, files configured as native (CRLF by default) will be converted  to  LF  when  stored  in  the
       repository.  Files  declared as LF, CRLF, or BIN in the [patterns] section are always stored as-is in the
       repository.

       Example versioned .hgeol file:

       [patterns]
       **.py = native
       **.vcproj = CRLF
       **.txt = native
       Makefile = LF
       **.jpg = BIN

       [repository]
       native = LF

       Note   The rules will first apply when files are touched in the working copy, e.g. by  updating  to  null
              and back to tip to touch all files.

       The  extension uses an optional [eol] section read from both the normal Mercurial configuration files and
       the .hgeol file, with the latter overriding the former. You can use that section to control  the  overall
       behavior. There are three settings:

       • eol.native  (default  os.linesep)  can  be  set to LF or CRLF to override the default interpretation of
         native for checkout. This can be used with hg archive on Unix, say, to generate an archive where  files
         have line endings for Windows.

       • eol.only-consistent  (default  True)  can  be  set  to  False  to make the extension convert files with
         inconsistent EOLs. Inconsistent means that there is both CRLF and LF present in the file.   Such  files
         are normally not touched under the assumption that they have mixed EOLs on purpose.

       • eol.fix-trailing-newline  (default  False) can be set to True to ensure that converted files end with a
         EOL character (either \n or \r\n as per the configured patterns).

       The extension provides cleverencode: and cleverdecode: filters like the  deprecated  win32text  extension
       does. This means that you can disable win32text and enable eol and your filters will still work. You only
       need to these filters until you have prepared a .hgeol file.

       The  win32text.forbid*  hooks  provided  by  the win32text extension have been unified into a single hook
       named eol.checkheadshook. The hook will lookup the expected line endings  from  the  .hgeol  file,  which
       means  you  must  migrate  to  a  .hgeol file first before using the hook. eol.checkheadshook only checks
       heads, intermediate invalid revisions will be pushed. To forbid them completely, use the eol.checkallhook
       hook. These hooks are best used as pretxnchangegroup hooks.

       See hg help patterns for more information about the glob patterns used.

   extdiff
       command to allow external programs to compare revisions

       The extdiff Mercurial extension allows you to use external programs to  compare  revisions,  or  revision
       with  working directory. The external diff programs are called with a configurable set of options and two
       non-option arguments: paths to directories containing snapshots of files to compare.

       The extdiff extension also allows you to configure new diff commands, so you  do  not  need  to  type  hg
       extdiff -p kdiff3 always.

       [extdiff]
       # add new command that runs GNU diff(1) in 'context diff' mode
       cdiff = gdiff -Nprc5
       ## or the old way:
       #cmd.cdiff = gdiff
       #opts.cdiff = -Nprc5

       # add new command called vdiff, runs kdiff3
       vdiff = kdiff3

       # add new command called meld, runs meld (no need to name twice)
       meld =

       # add new command called vimdiff, runs gvimdiff with DirDiff plugin
       # (see http://www.vim.org/scripts/script.php?script_id=102) Non
       # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
       # your .vimrc
       vimdiff = gvim -f "+next" \
                 "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"

       Tool arguments can include variables that are expanded at runtime:

       $parent1, $plabel1 - filename, descriptive label of first parent
       $child,   $clabel  - filename, descriptive label of child revision
       $parent2, $plabel2 - filename, descriptive label of second parent
       $root              - repository root
       $parent is an alias for $parent1.

       The  extdiff extension will look in your [diff-tools] and [merge-tools] sections for diff tool arguments,
       when none are specified in [extdiff].

       [extdiff]
       kdiff3 =

       [diff-tools]
       kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child

       You can use -I/-X and list of file or directory names like normal hg diff command. The extdiff  extension
       makes  snapshots  of only needed files, so running the external diff program will actually be pretty fast
       (at least faster than having to compare the entire tree).

   Commands
   extdiff
       hg extdiff [OPT]... [FILE]...

       Show differences between revisions for the specified  files,  using  an  external  program.  The  default
       program used is diff, with default options "-Npru".

       To  select  a different program, use the -p/--program option. The program will be passed the names of two
       directories to compare. To pass additional options to the program, use -o/--option. These will be  passed
       before the names of the directories to compare.

       When  two  revision  arguments  are  given,  then  changes are shown between those revisions. If only one
       revision is specified then that revision is compared to the working directory, and, when no revisions are
       specified, the working directory files are compared to its parent.

       Options:

       -p, --program
              comparison program to run

       -o, --option
              pass option to comparison program

       -r, --rev
              revision

       -c, --change
              change made by revision

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   factotum
       http authentication with factotum

       This extension  allows  the  factotum(4)  facility  on  Plan  9  from  Bell  Labs  platforms  to  provide
       authentication  information  for HTTP access. Configuration entries specified in the auth section as well
       as authentication information provided in the repository  URL  are  fully  supported.  If  no  prefix  is
       specified, a value of "*" will be assumed.

       By default, keys are specified as:

       proto=pass service=hg prefix=<prefix> user=<username> !password=<password>

       If the factotum extension is unable to read the required key, one will be requested interactively.

       A configuration section is available to customize runtime behavior. By default, these entries are:

       [factotum]
       executable = /bin/auth/factotum
       mountpoint = /mnt/factotum
       service = hg

       The  executable entry defines the full path to the factotum binary. The mountpoint entry defines the path
       to the factotum file service. Lastly, the service entry controls the service name used when reading keys.

   fetch
       pull, update and merge in one command (DEPRECATED)

   Commands
   fetch
       hg fetch [SOURCE]

       This finds all changes from the repository at the specified path or  URL  and  adds  them  to  the  local
       repository.

       If  the  pulled  changes  add  a new branch head, the head is automatically merged, and the result of the
       merge is committed.  Otherwise, the working directory is updated to include the new changes.

       When a merge is needed, the working directory is first updated to the newly pulled changes. Local changes
       are then merged into the pulled changes. To switch the merge order, use --switch-parent.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success.

       verify all the signatures there may be for a particular revision

   sign
       hg sign [OPTION]... [REV]...

       If no revision is given, the parent of the working directory is used, or tip if no  revision  is  checked
       out.

       See hg help dates for a list of formats valid for -d/--date.

       Options:

       -l, --local

       list signed changesets

   graphlog
       command to view revision graphs from a shell

       This  extension  adds  a  --graph option to the incoming, outgoing and log commands. When this options is
       given, an ASCII representation of the revision graph is also shown.

   Commands
   glog
       hg glog [OPTION]... [FILE]

   hgcia
       hooks for integrating with the CIA.vc notification service

       This is meant to be run as a changegroup or incoming hook. To configure it, set the following options  in
       your hgrc:

       [cia]
       # your registered CIA user name
       user = foo
       # the name of the project in CIA
       project = foo
       # the module (subproject) (optional)
       #module = foo
       # Append a diffstat to the log message (optional)
       #diffstat = False
       # Template to use for log messages (optional)
       #template = {desc}\n{baseurl}{webroot}/rev/{node}-- {diffstat}
       # Style to use (optional)
       #style = foo
       # The URL of the CIA notification service (optional)
       # You can use mailto: URLs to send by email, e.g.
       # mailto:cia@cia.vc

       #url = http://cia.vc/
       # print message instead of sending it (optional)
       #test = False
       # number of slashes to strip for url paths
       #strip = 0

       [hooks]
       # one of these:
       changegroup.cia = python:hgcia.hook
       #incoming.cia = python:hgcia.hook

   hgk
       browse the repository in a graphical way

       The  hgk  extension  allows  browsing  the history of a repository in a graphical way. It requires Tcl/Tk
       version 8.4 or later. (Tcl/Tk is not distributed with Mercurial.)

       hgk consists of two parts: a Tcl script that does the displaying and  querying  of  information,  and  an
       extension to Mercurial named hgk.py, which provides hooks for hgk to get information. hgk can be found in
       the contrib directory, and the extension is shipped in the hgext repository, and needs to be enabled.

       The  hg view command will launch the hgk Tcl script. For this command to work, hgk must be in your search
       path. Alternately, you can specify the path to hgk in your configuration file:

       [hgk]
       path=/location/of/hgk

       hgk can make use of the extdiff extension to visualize revisions.  Assuming you  had  already  configured
       extdiff vdiff command, just add:

       [hgk]
       vdiff=vdiff

       Revisions  context  menu  will  now  display  additional  entries  to  fire vdiff on hovered and selected
       revisions.

   Commands
   view
       hg view [-l LIMIT] [REVRANGE]

       start interactive history viewer

       Options:

       -l, --limit
              limit number of changes displayed

   highlight
       syntax highlighting for hgweb (requires Pygments)

       It depends on the Pygments syntax highlighting library: http://pygments.org/

       There is a single configuration option:

       [web]
       pygments_style = <style>

       The default is 'colorful'.

   histedit
       interactive history editing

       With this extension installed, Mercurial gains one new command: histedit. Usage is as  follows,  assuming
       the following history:

       @  3[tip]   7c2fd3b9020c   2009-04-27 18:04 -0500   durin42
       |    Add delta
       |
       o  2   030b686bedc4   2009-04-27 18:04 -0500   durin42
       |    Add gamma
       |
       o  1   c561b4e977df   2009-04-27 18:04 -0500   durin42
       |    Add beta
       |
       o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
            Add alpha

       If you were to run hg histedit c561b4e977df, you would see the following file open in your editor:

       pick c561b4e977df Add beta
       pick 030b686bedc4 Add gamma
       pick 7c2fd3b9020c Add delta

       # Edit history between c561b4e977df and 7c2fd3b9020c
       #
       # Commands:
       #  p, pick = use commit
       #  e, edit = use commit, but stop for amending
       #  f, fold = use commit, but fold into previous commit (combines N and N-1)
       #  d, drop = remove commit from history
       #  m, mess = edit message without changing commit content
       #

       In  this  file,  lines  beginning  with  # are ignored. You must specify a rule for each revision in your
       history. For example, if you had meant to add gamma before beta, and then wanted to add delta in the same
       revision as beta, you would reorganize the file to look like this:

       pick 030b686bedc4 Add gamma
       pick c561b4e977df Add beta
       fold 7c2fd3b9020c Add delta

       # Edit history between c561b4e977df and 7c2fd3b9020c
       #
       # Commands:
       #  p, pick = use commit
       #  e, edit = use commit, but stop for amending
       #  f, fold = use commit, but fold into previous commit (combines N and N-1)
       #  d, drop = remove commit from history
       #  m, mess = edit message without changing commit content
       #

       At which point you close the editor and histedit starts working.  When  you  specify  a  fold  operation,
       histedit  will  open  an editor when it folds those revisions together, offering you a chance to clean up
       the commit message:

       Add beta
       ***
       Add delta

       Edit the commit message to your liking, then close the editor. For this example, let's  assume  that  the
       commit  message  was changed to Add beta and delta. After histedit has run and had a chance to remove any
       old or temporary revisions it needed, the history looks like this:

       @  2[tip]   989b4d060121   2009-04-27 18:04 -0500   durin42
       |    Add beta and delta.
       |
       o  1   081603921c3f   2009-04-27 18:04 -0500   durin42
       |    Add gamma
       |
       o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
            Add alpha

       Note that histedit does not remove any revisions (even  its  own  temporary  ones)  until  after  it  has
       completed  all  the  editing  operations,  so it will probably perform several strip operations when it's
       done. For the above example, it had to run strip twice. Strip can be  slow  depending  on  a  variety  of
       factors,  so  you  might  need  to  be a little patient. You can choose to keep the original revisions by
       passing the --keep flag.

       The edit operation will drop you back to a command prompt, allowing you to edit files freely, or even use
       hg record to commit some changes as a separate  commit.  When  you're  done,  any  remaining  uncommitted
       changes  will  be committed as well. When done, run hg histedit --continue to finish this step. You'll be
       prompted for a new commit message, but the default commit message will be the original  message  for  the
       edit ed revision.

       The  message  operation  will give you a chance to revise a commit message without changing the contents.
       It's a shortcut for doing edit immediately followed by hg histedit --continue`.

       If histedit encounters a conflict when moving a revision (while handling pick or fold), it'll stop  in  a
       similar  manner  to  edit with the difference that it won't prompt you for a commit message when done. If
       you decide at this point that you don't like how much work it will be to rearrange history, or  that  you
       made  a  mistake,  you can use hg histedit --abort to abandon the new changes you have made and return to
       the state before you attempted to edit your history.

       If we clone the histedit-ed example repository above and add four more changes, such  that  we  have  the
       following history:

       @  6[tip]   038383181893   2009-04-27 18:04 -0500   stefan

       If  you  run hg histedit --outgoing on the clone then it is the same as running hg histedit 836302820282.
       If you need plan to push to a repository that Mercurial does not detect to be related to the source repo,
       you can add a --force option.

   Commands
   histedit
       hg histedit ANCESTOR | --outgoing [URL]

       This command edits changesets between ANCESTOR and the parent of the working directory.

       With --outgoing, this edits changesets not found in the destination repository. If URL of the destination
       is omitted, the 'default-push' (or 'default') path will be used.

       For safety, this command is aborted, also if there are ambiguous outgoing  revisions  which  may  confuse
       users: for example, there are multiple branches containing outgoing revisions.

       Use  "min(outgoing()  and  ::.)"  or  similar  revset specification instead of --outgoing to specify edit
       target revision exactly in such ambiguous situation. See  hg  help  revsets for  detail  about  selecting
       revisions.

       Returns  0  on  success, 1 if user intervention is required (not only for intentional "edit" command, but
       also for resolving unexpected conflicts).

       Options:

       --commands
              Read history edits from the specified file.

       -c, --continue
              continue an edit already in progress

       -k, --keep
              don't strip old nodes after edit is complete

       --abort
              abort an edit in progress

       -o, --outgoing
              changesets not found in destination

       -f, --force
              force outgoing even for unrelated repositories

       -r, --rev
              first revision to be edited

   inotify
       accelerate status report using Linux's inotify service

   Commands
   inserve
       hg inserve [OPTION]...

       start an inotify server for this repository

       Options:

       -d, --daemon
              run server in background

       --daemon-pipefds
              used internally by daemon mode

       -t, --idle-timeout
              minutes to sit idle before exiting

       --pid-file
              name of file to write process ID to

   interhg
       None

   keyword
       expand keywords in tracked files

       This extension expands RCS/CVS-like or self-customized $Keywords$ in tracked text files selected by  your
       configuration.

       Keywords  are only expanded in local repositories and not stored in the change history. The mechanism can
       be regarded as a convenience for the current user or for archive distribution.

       Keywords expand to the changeset data pertaining to the latest change relative to the  working  directory
       parent of each file.

       Configuration is done in the [keyword], [keywordset] and [keywordmaps] sections of hgrc files.

       Example:

       [keyword]
       # expand keywords in every python file except those matching "x*"
       **.py =
       x*    = ignore

       [keywordset]
       # prefer svn- over cvs-like default keywordmaps
       svn = True

       Note   The more specific you are in your filename patterns the less you lose speed in huge repositories.

       For  [keywordmaps]  template  mapping  and expansion demonstration and control run hg kwdemo. See hg help
       templates for a list of available templates and filters.

       Three additional date template filters are provided:

       utcdate

              "2006/09/18 15:13:13"

       svnutcdate

              "2006-09-18 15:13:13Z"

       svnisodate

              "2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"

       The default template mappings (view with hg kwdemo -d) can  be  replaced  with  customized  keywords  and
       templates. Again, run hg kwdemo to control the results of your configuration changes.

       Before changing/disabling active keywords, you must run hg kwshrink to avoid storing expanded keywords in
       the change history.

       To force expansion after enabling it, or a configuration change, run hg kwexpand.

       Expansions  spanning more than one line and incremental expansions, like CVS' $Log$, are not supported. A
       keyword template map "Log = {desc}" expands to the first line of the changeset description.

   Commands
   kwdemo
       hg kwdemo [-d] [-f RCFILE] [TEMPLATEMAP]...

       Show current, custom, or default keyword template maps and their expansions.

       Extend the current configuration by specifying maps as arguments  and  using  -f/--rcfile  to  source  an
       external hgrc file.

       Use -d/--default to disable current configuration.

       See hg help templates for information on templates and filters.

       Options:

       -d, --default
              show default keyword template maps

       -f, --rcfile
              read maps from rcfile

   kwexpand
       hg kwexpand [OPTION]... [FILE]...

       Run after (re)enabling keyword expansion.

       kwexpand refuses to run if given files contain local changes.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   kwfiles
       hg kwfiles [OPTION]... [FILE]...

       List which files in the working directory are matched by the [keyword] configuration patterns.

       Useful  to  prevent  inadvertent keyword expansion and to speed up execution by including only files that
       are actual candidates for expansion.

       See hg help keyword on how to construct patterns both for inclusion and exclusion of files.

       With -A/--all and -v/--verbose the codes used to show the status of files are:

       K = keyword expansion candidate
       k = keyword expansion candidate (not tracked)
       I = ignored
       i = ignored (not tracked)

       Options:

       -A, --all
              show keyword status flags of all files

       -i, --ignore
              show files excluded from expansion

       -u, --unknown
              only show unknown (not tracked) files

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   kwshrink
       hg kwshrink [OPTION]... [FILE]...

       Must be run before changing/disabling active keywords.

       kwshrink refuses to run if given files contain local changes.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   largefiles
       track large binary files

       Large binary files tend to be not very compressible, not very diffable, and not at  all  mergeable.  Such
       files  are  not  handled efficiently by Mercurial's storage format (revlog), which is based on compressed
       binary deltas; storing large binary files as regular Mercurial files wastes bandwidth and disk space  and
       increases  Mercurial's  memory  usage.  The  largefiles  extension  addresses  these problems by adding a
       centralized client-server layer on top of Mercurial: largefiles live  in  a  central  store  out  on  the
       network somewhere, and you only fetch the revisions that you need when you need them.

       largefiles works by maintaining a "standin file" in .hglf/ for each largefile. The standins are small (41
       bytes:  an  SHA-1  hash plus newline) and are tracked by Mercurial. Largefile revisions are identified by
       the SHA-1 hash of their contents, which is written to the standin. largefiles uses that  revision  ID  to
       get/put  largefile  revisions  from/to the central store. This saves both disk space and bandwidth, since
       you don't need to retrieve all historical revisions of large files when you clone or pull.

       To start a new repository or add new large binary files, just add --large to  your  hg  add command.  For
       example:

       $ dd if=/dev/urandom of=randomdata count=2000
       $ hg add --large randomdata
       $ hg commit -m 'add randomdata as a largefile'

       When  you  push a changeset that adds/modifies largefiles to a remote repository, its largefile revisions
       will be uploaded along with it.  Note that the remote Mercurial must also have the  largefiles  extension
       enabled for this to work.

       When  you  pull  a  changeset  that  affects  largefiles from a remote repository, the largefiles for the
       changeset will by default not be pulled down. However, when you update to such a revision, any largefiles
       needed by that revision are downloaded and cached (if they have never been downloaded before). One way to
       pull largefiles when pulling is thus to use --update, which will update your working copy to  the  latest
       pulled revision (and thereby downloading any new largefiles).

       If  you  want  to  pull  largefiles you don't need for update yet, then you can use pull with the --lfrev
       option or the hg lfpull command.

       If you know you are pulling from a non-default location and want to  download  all  the  largefiles  that
       correspond to the new changesets at the same time, then you can pull with --lfrev "pulled()".

       If  you  just  want  to ensure that you will have the largefiles needed to merge or rebase with new heads
       that you are pulling, then you can pull with --lfrev "head(pulled())" flag to pre-emptively download  any
       largefiles that are new in the heads you are pulling.

       Keep in mind that network access may now be required to update to changesets that you have not previously
       updated  to.  The  nature of the largefiles extension means that updating is no longer guaranteed to be a
       local-only operation.

       If you already have large files tracked by Mercurial without the largefiles extension, you will  need  to
       convert your repository in order to benefit from largefiles. This is done with the hg lfconvert command:

       $ hg lfconvert --size 10 oldrepo newrepo

       In  repositories that already have largefiles in them, any new file over 10MB will automatically be added
       as a largefile. To change this threshold, set largefiles.minsize in your Mercurial  config  file  to  the
       minimum size in megabytes to track as a largefile, or use the --lfsize option to the add command (also in
       megabytes):

       [largefiles]
       minsize = 2

       $ hg add --lfsize 2

       The  largefiles.patterns  config  option  allows  you to specify a list of filename patterns (see hg help
       patterns) that should always be tracked as largefiles:

       [largefiles]
       patterns =
         *.jpg
         re:.*\.(png|bmp)$
         library.zip
         content/audio/*

       Files that match one of these patterns will be added as largefiles regardless of their size.

       The largefiles.minsize and largefiles.patterns config options will be ignored for  any  repositories  not
       already  containing  a  largefile.  To add the first largefile to a repository, you must explicitly do so
       with the --large flag passed to the hg add command.

   Commands
   lfconvert
       hg lfconvert SOURCE DEST [FILE ...]

       Convert repository SOURCE to a new repository DEST, identical to SOURCE except that certain files will be
       converted as largefiles: specifically, any file that matches any PATTERN  or  whose  size  is  above  the
       minimum  size threshold is converted as a largefile. The size used to determine whether or not to track a
       file as a largefile is the size of the first version of the file.  The  minimum  size  can  be  specified
       either with --size or in configuration as largefiles.size.

       After  running  this command you will need to make sure that largefiles is enabled anywhere you intend to
       push the new repository.

       Use --to-normal to convert largefiles back to normal files; after this, the DEST repository can  be  used
       without largefiles at all.

       Options:

       -s, --size
              minimum size (MB) for files to be converted as largefiles

       --to-normal
              convert from a largefiles repo to a normal repo

   lfpull
       hg lfpull -r REV... [-e CMD] [--remotecmd CMD] [SOURCE]

       Pull  largefiles  that  are  referenced  from local changesets but missing locally, pulling from a remote
       repository to the local cache.

       If SOURCE is omitted, the 'default' path will be used.  See hg help urls for more information.

       Some examples:

       • pull largefiles for all branch heads:

         hg lfpull -r "head() and not closed()"

       • pull largefiles on the default branch:

         hg lfpull -r "branch(default)"

       Options:

       -r, --rev
              pull largefiles for these revisions

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts config)

   mq
       manage a stack of patches

       This extension lets you work with a stack of patches in a Mercurial repository. It manages two stacks  of
       patches - all known patches, and applied patches (subset of known patches).

       Known patches are represented as patch files in the .hg/patches directory. Applied patches are both patch
       files and changesets.

       Common tasks (use hg help command for more details):

       create new patch                          qnew
       import existing patch                     qimport

       print patch series                        qseries
       print applied patches                     qapplied

       add known patch to applied stack          qpush
       remove patch from applied stack           qpop
       refresh contents of top applied patch     qrefresh

       By  default,  mq will automatically use git patches when required to avoid losing file mode changes, copy
       records, binary files or empty files creations or deletions. This behaviour can be configured with:

       [mq]
       git = auto/keep/yes/no

       If set to 'keep', mq will obey the [diff] section configuration while  preserving  existing  git  patches
       upon  qrefresh.  If  set to 'yes' or 'no', mq will override the [diff] section and always generate git or
       regular patches, possibly losing data in the second case.

       It may be desirable for mq changesets to be kept in the secret phase (see hg help phases), which  can  be
       enabled with the following setting:

       [mq]
       secret = True

       You  will  by  default be managing a patch queue named "patches". You can create other, independent patch
       queues with the hg qqueue command.

       If the working directory contains  uncommitted  files,  qpush,  qpop  and  qgoto  abort  immediately.  If
       -f/--force is used, the changes are discarded. Setting:

       [mq]
       keepchanges = True

       make  them  behave  as if --keep-changes were passed, and non-conflicting local changes will be tolerated
       and preserved. If incompatible options such as -f/--force or --exact are passed, this setting is ignored.

       This extension used to provide a strip command. This command now lives in the strip extension.

   Commands
   qapplied
       hg qapplied [-1] [-s] [PATCH]

       Returns 0 on success.

       Options:

       -1, --last
              show only the preceding applied patch

       -s, --summary
              print first line of patch header

   qclone
       hg qclone [OPTION]... SOURCE [DEST]

       If source is local, destination will have no patches applied. If source is remote, this command  can  not
       check  if patches are applied in source, so cannot guarantee that patches are not applied in destination.
       If you clone remote repository, be sure before that it has no patches applied.

       Source patch repository is looked for in <src>/.hg/patches by default. Use -p <url> to change.

       The patch directory must be a nested Mercurial repository, as would be created by hg init --mq.

       Return 0 on success.

       Options:

       --pull use pull protocol to copy metadata

       -U, --noupdate

   qdelete
       hg qdelete [-k] [PATCH]...

       The patches must not be applied, and at least one patch is required.  Exact  patch  identifiers  must  be
       given. With -k/--keep, the patch files are preserved in the patch directory.

       To stop managing a patch and move it into permanent history, use the hg qfinish command.

       Options:

       -k, --keep
              keep patch file

       -r, --rev
              stop managing a revision (DEPRECATED)

       hg qdiff [OPTION]... [FILE]...

       Shows  a diff which includes the current patch as well as any changes which have been made in the working
       directory since the last refresh (thus showing what the current patch would become after a qrefresh).

       Use hg diff if you only want to see the changes made since the last qrefresh, or hg  export  qtip if  you
       want to see changes made by the current patch without including changes made since the qrefresh.

       Returns 0 on success.

       -X, --exclude
              exclude names matching the given patterns

   qfinish
       hg qfinish [-a] [REV]...

       Finishes the specified revisions (corresponding to applied patches) by moving them out of mq control into
       regular repository history.

       Accepts  a revision range or the -a/--applied option. If --applied is specified, all applied mq revisions
       are removed from mq control. Otherwise, the given revisions must be at the base of the stack  of  applied
       patches.

       This  can be especially useful if your changes have been applied to an upstream repository, or if you are
       about to push your changes to upstream.

       Returns 0 on success.

       Options:

       -a, --applied
              finish all applied changesets

   qfold
       hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...

       Patches must not yet be applied. Each patch will be successively applied to  the  current  patch  in  the
       order  given.  If  all  the  patches apply successfully, the current patch will be refreshed with the new
       cumulative patch, and the folded patches will be deleted. With -k/--keep, the folded patch files will not
       be removed afterwards.

       The header for each folded patch will be concatenated with the current patch header, separated by a  line
       of * * *.

       Returns 0 on success.

       Options:

       -e, --edit
              edit patch header

       -k, --keep
              keep folded patch files

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   qgoto
       hg qgoto [OPTION]... PATCH

       Returns 0 on success.

       Options:

       --keep-changes
              tolerate non-conflicting local changes

       -f, --force
              overwrite any local changes

       --no-backup
              do not save backup copies of files

   qguard
       hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]

       Guards  control  whether  a  patch can be pushed. A patch with no guards is always pushed. A patch with a
       positive guard ("+foo") is pushed only if the hg  qselect command  has  activated  it.  A  patch  with  a
       negative guard ("-foo") is never pushed if the hg qselect command has activated it.

       With no arguments, print the currently active guards.  With arguments, set guards for the named patch.

       Note   Specifying negative guards now requires '--'.

       To set guards on another patch:

       hg qguard other.patch -- +2.6.17 -stable

       Returns 0 on success.

       Options:

       -l, --list
              list all patches and guards

       -n, --none
              drop all guards

   qheader
       hg qheader [PATCH]

       Returns 0 on success.

   qimport
       hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... [FILE]...

       The  patch  is  inserted  into  the series after the last applied patch. If no patches have been applied,
       qimport prepends the patch to the series.

       The patch will have the same name as its source file unless you give it a new one with -n/--name.

       You can register an existing patch inside the patch directory with the -e/--existing flag.

       With -f/--force, an existing patch of the same name will be overwritten.

       An existing changeset may be placed under mq control with -r/--rev (e.g. qimport --rev .  -n  patch  will
       place the current revision under mq control). With -g/--git, patches imported with --rev will use the git
       diff format. See the diffs help topic for information on why this is important for preserving rename/copy
       information and permission changes. Use hg qfinish to remove changesets from mq control.

       To  import  a patch from standard input, pass - as the patch file.  When importing from standard input, a
       patch name must be specified using the --name flag.

       To import an existing patch while renaming it:

       hg qimport -e existing-patch -n new-name

       Returns 0 if import succeeded.

       Options:

       -e, --existing
              import file in patch directory

       -n, --name
              name of patch file

       -f, --force
              overwrite existing files

       -r, --rev
              place existing revisions under mq control

       -g, --git
              use git extended diff format

       -P, --push
              qpush after importing

   qinit
       hg qinit [-c]

       The queue repository is unversioned by default. If -c/--create-repo is specified,  qinit  will  create  a
       separate  nested  repository  for patches (qinit -c may also be run later to convert an unversioned patch
       repository into a versioned one). You can use qcommit to commit changes to this queue repository.

       This command is deprecated. Without -c, it's implied by other relevant commands. With  -c,  use  hg  init
       --mq instead.

       Options:

       -c, --create-repo
              create queue repository

   qnew
       hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...

       qnew  creates  a  new patch on top of the currently-applied patch (if any). The patch will be initialized
       with any outstanding changes in the working directory.  You  may  also  use  -I/--include,  -X/--exclude,
       and/or  a  list  of  files  after  the patch name to add only changes to matching files to the new patch,
       leaving the rest as uncommitted modifications.

       -u/--user and -d/--date can be used to set the (given) user and date, respectively. -U/--currentuser  and
       -D/--currentdate set user to current user and date to current date.

       -e/--edit,  -m/--message  or  -l/--logfile set the patch header as well as the commit message. If none is
       specified, the header is empty and the commit message is '[mq]: PATCH'.

       Use the -g/--git option to keep the patch in the git extended diff format. Read the diffs help topic  for
       more information on why this is important for preserving permission changes and copy/rename information.

       Returns 0 on successful creation of a new patch.

       Options:

       -e, --edit
              edit commit message

       -f, --force
              import uncommitted changes (DEPRECATED)

       -g, --git
              use git extended diff format

       -U, --currentuser
              add "From: <current user>" to patch

       -u, --user
              add "From: <USER>" to patch

       -D, --currentdate
              add "Date: <current date>" to patch

       -d, --date
              add "Date: <DATE>" to patch

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   qnext
       hg qnext [-s]

       Returns 0 on success.

       Options:

       -s, --summary
              print first line of patch header

   qpop
       hg qpop [-a] [-f] [PATCH | INDEX]

       Without  argument,  pops off the top of the patch stack. If given a patch name, keeps popping off patches
       until the named patch is at the top of the stack.

       By default, abort if the working directory contains uncommitted changes. With --keep-changes, abort  only
       if  the uncommitted files overlap with patched files. With -f/--force, backup and discard changes made to
       such files.

       Return 0 on success.

       Options:

       -a, --all
              pop all patches

       -n, --name
              queue name to pop (DEPRECATED)

       --keep-changes
              tolerate non-conflicting local changes

       -f, --force
              forget any local changes to patched files

       --no-backup
              do not save backup copies of files

   qprev
       hg qprev [-s]

       Returns 0 on success.

       Options:

       -s, --summary
              print first line of patch header

   qpush
       hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]

       By default, abort if the working directory contains uncommitted changes. With --keep-changes, abort  only
       if  the  uncommitted files overlap with patched files. With -f/--force, backup and patch over uncommitted
       changes.

       Return 0 on success.

       Options:

       --keep-changes
              tolerate non-conflicting local changes

       -f, --force
              apply on top of local changes

       -e, --exact
              apply the target patch to its recorded parent

       -l, --list
              list patch name in commit text

       -a, --all
              apply all patches

       -m, --merge
              merge from another queue (DEPRECATED)

       -n, --name
              merge queue name (DEPRECATED)

       --move reorder patch series and apply only the patch

       --no-backup
              do not save backup copies of files

   qqueue
       hg qqueue [OPTION] [QUEUE]

       Supports switching between different patch queues, as well as creating  new  patch  queues  and  deleting
       existing ones.

       Omitting  a  queue  name  or  specifying  -l/--list  will show you the registered queues - by default the
       "normal" patches queue is registered.  The  currently  active  queue  will  be  marked  with  "(active)".
       Specifying --active will print only the name of the active queue.

       To  create a new queue, use -c/--create. The queue is automatically made active, except in the case where
       there are applied patches from the currently active queue in the repository. Then the queue will only  be
       created and switching will fail.

       To delete an existing queue, use --delete. You cannot delete the currently active queue.

       Returns 0 on success.

       Options:

       -l, --list
              list all available queues

       --active
              print name of active queue

       -c, --create
              create new queue

       --rename
              rename active queue

       --delete
              delete reference to queue

       --purge
              delete queue, and remove patch dir

   qrefresh
       hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...

       If  any  file  patterns  are provided, the refreshed patch will contain only the modifications that match
       those patterns; the remaining modifications will remain in the working directory.

       If -s/--short is specified, files currently included in the patch will be  refreshed  just  like  matched
       files and remain in the patch.

       If  -e/--edit  is  specified,  Mercurial will start your configured editor for you to enter a message. In
       case qrefresh fails, you will find a backup of your message in .hg/last-message.txt.

       hg add/remove/copy/rename work as usual, though you might want to  use  git-style  patches  (-g/--git  or
       [diff]  git=1) to track copies and renames. See the diffs help topic for more information on the git diff
       format.

       Returns 0 on success.

       Options:

       -e, --edit
              edit commit message

       -g, --git
              use git extended diff format

       -s, --short
              refresh only files already in the patch and specified files

       -U, --currentuser
              add/update author field in patch with current user

       -u, --user
              add/update author field in patch with given user

              add/update date field in patch with current date

       -d, --date
              add/update date field in patch with given date

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   qrename
       hg qrename PATCH1 [PATCH2]

       With one argument, renames the current patch to PATCH1.  With two arguments, renames PATCH1 to PATCH2.

       Returns 0 on success.

          aliases: qmv

   qrestore
       hg qrestore [-d] [-u] REV

       This command is deprecated, use hg rebase instead.

       Options:

       -d, --delete
              delete save entry

       -u, --update
              update queue working directory

   qsave
       hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]

       This command is deprecated, use hg rebase instead.

       Options:

   qselect
       hg qselect [OPTION]... [GUARD]...

       Use the hg qguard command to set or print guards on patch, then use qselect to tell mq  which  guards  to
       use.  A  patch  will  be  pushed  if it has no guards or any positive guards match the currently selected
       guard, but will not be pushed if any negative guards match the current guard. For example:

       qguard foo.patch -- -stable    (negative guard)
       qguard bar.patch    +stable    (positive guard)
       qselect stable

       This activates the "stable" guard. mq will skip foo.patch (because it has  a  negative  match)  but  push
       bar.patch (because it has a positive match).

       With no arguments, prints the currently active guards.  With one argument, sets the active guard.

       Use  -n/--none to deactivate guards (no other arguments needed).  When no guards are active, patches with
       positive guards are skipped and patches with negative guards are pushed.

       qselect can change the guards on applied patches. It does not pop guarded patches by default.  Use  --pop
       to  pop  back  to the last applied patch that is not guarded. Use --reapply (which implies --pop) to push
       back to the current patch afterwards, but skip guarded patches.

       Use -s/--series to print a list of all guards in the series file (no other arguments needed). Use -v  for
       more information.

       Returns 0 on success.

       Options:

       -n, --none
              disable all guards

       -s, --series
              list all guards in series file

   notify
       hooks for sending email push notifications

       This  extension implements hooks to send email notifications when changesets are sent from or received by
       the local repository.

       First, enable the extension as explained in hg help extensions, and register the hook you  want  to  run.
       incoming  and  changegroup  hooks  are  run  when  changesets  are received, while outgoing hooks are for
       changesets sent to another repository:

       [hooks]
       # one email for each incoming changeset
       incoming.notify = python:hgext.notify.hook
       # one email for all incoming changesets
       changegroup.notify = python:hgext.notify.hook

       # one email for all outgoing changesets
       outgoing.notify = python:hgext.notify.hook

       This registers the hooks. To enable notification, subscribers  must  be  assigned  to  repositories.  The
       [usersubs]  section maps multiple repositories to a given recipient. The [reposubs] section maps multiple
       recipients to a single repository:

       [usersubs]
       # key is subscriber email, value is a comma-separated list of repo patterns
       user@host = pattern

       [reposubs]
       # key is repo pattern, value is a comma-separated list of subscriber emails
       pattern = user@host

       A pattern is a glob matching the absolute path  to  a  repository,  optionally  combined  with  a  revset
       expression. A revset expression, if present, is separated from the glob by a hash. Example:

       [reposubs]
       */widgets#branch(release) = qa-team@example.com

       This  sends  to qa-team@example.com whenever a changeset on the release branch triggers a notification in
       any repository ending in widgets.

       In order to place them under direct user management, [usersubs] and [reposubs] sections may be placed  in
       a separate hgrc file and incorporated by reference:

       [notify]
       config = /path/to/subscriptionsfile

       Notifications will not be sent until the notify.test value is set to False; see below.

       Notifications content can be tweaked with the following configuration entries:

       notify.test
              If True, print messages to stdout instead of sending them. Default: True.

       notify.sources
              Space-separated list of change sources. Notifications are activated only when a changeset's source
              is in this list. Sources may be:

              serve

                     changesets received via http or ssh

              pull

                     changesets received via hg pull

              unbundle

                     changesets received via hg unbundle

              push

                     changesets sent or received via hg push

              bundle

                     changesets sent via hg unbundle

              Default: serve.

       notify.strip
              Number  of  leading  slashes  to  strip  from  url  paths.  By  default,  notifications  reference
              repositories with their absolute path. notify.strip lets you turn them into  relative  paths.  For
              example, notify.strip=3 will change /long/path/repository into repository. Default: 0.

       notify.domain
              Default email domain for sender or recipients with no explicit domain.

       notify.style
              Style file to use when formatting emails.

       notify.template
              Template to use when formatting emails.

       notify.incoming
              Template to use when run as an incoming hook, overriding notify.template.

       notify.outgoing
              Template to use when run as an outgoing hook, overriding notify.template.

       notify.changegroup
              Template to use when running as a changegroup hook, overriding notify.template.

       notify.maxdiff
              Maximum number of diff lines to include in notification email. Set to 0 to disable the diff, or -1
              to include all of it. Default: 300.

       notify.maxsubject
              Maximum number of characters in email's subject line. Default: 67.

       notify.diffstat
              Set to True to include a diffstat before diff content. Default: True.

       notify.merge
              If True, send notifications for merge changesets. Default: True.

       notify.mbox
              If set, append mails to this mbox file instead of sending. Default: None.

       notify.fromauthor
              If  set,  use  the  committer  of the first changeset in a changegroup for the "From" field of the
              notification mail. If not set, take the user from the pushing repo.  Default: False.

       If set, the following entries will also be used to customize the notifications:

       email.from
              Email From address to use if none can be found in the generated email content.

       web.baseurl
              Root  repository  URL  to  combine  with  repository  paths  when  making  references.  See   also
              notify.strip.

   pager
       browse command output with an external pager

       To set the pager that should be used, set the application variable:

       [pager]
       pager = less -FRX

       If  no  pager  is set, the pager extensions uses the environment variable $PAGER. If neither pager.pager,
       nor $PAGER is set, no pager is used.

       You can disable the pager for certain commands by adding them to the pager.ignore list:

       [pager]
       ignore = version, help, update

       You can also enable the pager only for certain commands using pager.attend. Below is the default list  of
       commands to be paged:

       [pager]
       attend = annotate, cat, diff, export, glog, log, qdiff

       Setting pager.attend to an empty value will cause all commands to be paged.

       If pager.attend is present, pager.ignore will be ignored.

       To ignore global commands like hg version or hg help, you have to specify them in your user configuration
       file.

       The  --pager=... option can also be used to control when the pager is used. Use a boolean value like yes,
       no, on, off, or use auto for normal behavior.

   patchbomb
       command to send changesets as (a series of) patch emails

       The series is started off with a "[PATCH 0 of N]" introduction, which describes the series as a whole.

       Each patch email has a Subject line of "[PATCH M of N] ...",  using  the  first  line  of  the  changeset
       description as the subject text. The message contains two or three body parts:

       • The changeset description.

       • [Optional] The result of running diffstat on the patch.

       • The patch itself, as generated by hg export.

       Each message refers to the first in the series using the In-Reply-To and References headers, so they will
       show up as a sequence in threaded mail and news readers, and in mail archives.

       To configure other defaults, add a section like this to your configuration file:

       [email]
       from = My Name <my@email>
       to = recipient1, recipient2, ...
       cc = cc1, cc2, ...
       bcc = bcc1, bcc2, ...
       reply-to = address1, address2, ...

       Use [patchbomb] as configuration section name if you need to override global [email] address settings.

       Then you can use the hg email command to mail a series of changesets as a patchbomb.

       You  can  also either configure the method option in the email section to be a sendmail compatible mailer
       or fill out the [smtp] section so that the patchbomb extension can automatically send patchbombs directly
       from the commandline. See the [email] and [smtp] sections in hgrc(5) for details.

   Commands
   email
       hg email [OPTION]... [DEST]...

       By default, diffs are sent in the format generated by hg export, one per message. The series starts  with
       a "[PATCH 0 of N]" introduction, which describes the series as a whole.

       Each  patch  email  has  a  Subject  line  of "[PATCH M of N] ...", using the first line of the changeset
       description as the subject text.   The  message  contains  two  or  three  parts.  First,  the  changeset
       description.

       With  the  -d/--diffstat  option, if the diffstat program is installed, the result of running diffstat on
       the patch is inserted.

       Finally, the patch itself, as generated by hg export.

       With the -d/--diffstat or --confirm options, you will be presented with a final summary of  all  messages
       and asked for confirmation before the messages are sent.

       By  default  the  patch  is  included as text in the email body for easy reviewing. Using the -a/--attach
       option will instead create an attachment for the patch. With -i/--inline an  inline  attachment  will  be
       created.  You can include a patch both as text in the email body and as a regular or an inline attachment
       by combining the -a/--attach or -i/--inline with the --body option.

       With -o/--outgoing, emails will be generated for patches not found in the destination repository (or only
       those which are ancestors of the specified revisions if any are provided)

       With -b/--bundle, changesets are selected as for --outgoing, but  a  single  email  containing  a  binary
       Mercurial bundle as an attachment will be sent.

       With -m/--mbox, instead of previewing each patchbomb message in a pager or sending the messages directly,
       it  will  create  a  UNIX mailbox file with the patch emails. This mailbox file can be previewed with any
       mail user agent which supports UNIX mbox files.

       With -n/--test, all steps will run, but mail will not be  sent.   You  will  be  prompted  for  an  email
       recipient  address, a subject and an introductory message describing the patches of your patchbomb.  Then
       when all is done, patchbomb messages are displayed. If the PAGER environment variable is set, your  pager
       will be fired up once for each patchbomb message, so you can verify everything is alright.

       In  case  email  sending  fails,  you  will  find  a  backup  of  your  series  introductory  message  in
       .hg/last-email.txt.

       Examples:

       hg email -r 3000          # send patch 3000 only
       hg email -r 3000 -r 3001  # send patches 3000 and 3001
       hg email -r 3000:3005     # send patches 3000 through 3005
       hg email 3000             # send patch 3000 (deprecated)

       hg email -o               # send all patches not in default
       hg email -o DEST          # send all patches not in DEST
       hg email -o -r 3000       # send all ancestors of 3000 not in default
       hg email -o -r 3000 DEST  # send all ancestors of 3000 not in DEST

       hg email -b               # send bundle of all patches not in default
       hg email -b DEST          # send bundle of all patches not in DEST
       hg email -b -r 3000       # bundle of all ancestors of 3000 not in default
       hg email -b -r 3000 DEST  # bundle of all ancestors of 3000 not in DEST

       hg email -o -m mbox &&    # generate an mbox file...
         mutt -R -f mbox         # ... and view it with mutt
       hg email -o -m mbox &&    # generate an mbox file ...
         formail -s sendmail \   # ... and use formail to send from the mbox
           -bm -t < mbox         # ... using sendmail

       Before using this command, you will need to enable email in your hgrc. See the [email] section in hgrc(5)
       for details.

              do not verify server certificate (ignoring web.cacerts config)

   progress
       show progress bars for some actions

       This extension uses the progress information logged by hg commands to draw  progress  bars  that  are  as
       informative  as  possible.  Some  progress bars only offer indeterminate information, while others have a
       definite end point.

       The following settings are available:

       [progress]
       delay = 3 # number of seconds (float) before showing the progress bar
       changedelay = 1 # changedelay: minimum delay before showing a new topic.
                       # If set to less than 3 * refresh, that value will
                       # be used instead.
       refresh = 0.1 # time in seconds between refreshes of the progress bar
       format = topic bar number estimate # format of the progress bar
       width = <none> # if set, the maximum width of the progress information
                      # (that is, min(width, term width) will be used)
       clear-complete = True # clear the progress bar after it's done
       disable = False # if true, don't show a progress bar
       assume-tty = False # if true, ALWAYS show a progress bar, unless
                          # disable is given

       Valid entries for the format field are topic, bar, number, unit, estimate, speed, and item. item defaults
       to the last 20 characters of the item, but this can be changed by adding either -<num> which  would  take
       the last num characters, or +<num> for the first num characters.

   purge
       command to delete untracked files from the working directory

   Commands
   purge
       hg purge [OPTION]... [DIR]...

       Delete  files  not  known  to  Mercurial.  This  is  useful  to  test local and uncommitted changes in an
       otherwise-clean source tree.

       This means that purge will delete:

       • Unknown files: files marked with "?" by hg status

       • Empty directories: in fact Mercurial ignores directories unless they contain files under source control
         management

       But it will leave untouched:

       • Modified and unmodified tracked files

       • Ignored files (unless --all is specified)

       • New files added to the repository (with hg add)

       If directories are given on the command line, only files in these directories are considered.

       Be careful with purge, as you could irreversibly delete some files you forgot to add to  the  repository.
       If you only want to print the list of files that this program would delete, use the --print option.

       Options:

       -a, --abort-on-err
              abort if an error occurs

       --all  purge ignored files too

       -p, --print
              print filenames instead of deleting them

       -0, --print0
              end filenames with NUL, for use with xargs (implies -p/--print)

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

              aliases: clean

   rebase
       command to move sets of revisions to a different ancestor

       This extension lets you rebase changesets in an existing Mercurial repository.

       For more information: http://mercurial.selenic.com/wiki/RebaseExtension

   Commands
   rebase
       hg rebase [-s REV | -b REV] [-d REV] [OPTION]

       Rebase  uses repeated merging to graft changesets from one part of history (the source) onto another (the
       destination). This can be useful for linearizing local changes relative to a master development tree.

       You should not rebase changesets that have already been shared with others. Doing so will force everybody
       else to perform the same rebase or they will end up with duplicated  changesets  after  pulling  in  your
       rebased changesets.

       In  its  default  configuration,  Mercurial will prevent you from rebasing published changes. See hg help
       phases for details.

       If you don't specify a destination changeset (-d/--dest), rebase uses  the  current  branch  tip  as  the
       destination.  (The destination changeset is not modified by rebasing, but new changesets are added as its
       descendants.)

       You can specify which changesets to rebase in two ways: as a "source" changeset or as a "base" changeset.
       Both are shorthand for a topologically related set of changesets (the "source branch").  If  you  specify
       source  (-s/--source),  rebase  will  rebase  that changeset and all of its descendants onto dest. If you
       specify base (-b/--base), rebase will select ancestors of base back  to  but  not  including  the  common
       ancestor  with  dest. Thus, -b is less precise but more convenient than -s: you can specify any changeset
       in the source branch, and rebase will select the whole branch. If you specify neither -s nor  -b,  rebase
       uses the parent of the working directory as the base.

       For  advanced  usage,  a  third  way  is  available through the --rev option. It allows you to specify an
       arbitrary set of changesets to rebase.  Descendants  of  revs  you  specify  with  this  option  are  not
       automatically included in the rebase.

       By default, rebase recreates the changesets in the source branch as descendants of dest and then destroys
       the  originals.  Use  --keep  to  preserve  the original source changesets. Some changesets in the source
       branch (e.g. merges from the destination branch) may be dropped if they no longer contribute any change.

       One result of the rules for selecting the destination changeset and source branch is that, unlike  merge,
       rebase  will  do  nothing  if  you  are  at  the branch tip of a named branch with two heads. You need to
       explicitly specify source and/or destination (or update to the other  head,  if  it's  the  head  of  the
       intended source branch).

       If a rebase is interrupted to manually resolve a merge, it can be continued with --continue/-c or aborted
       with --abort/-a.

       Returns 0 on success, 1 if nothing to rebase or there are unresolved conflicts.

       Options:

       -s, --source
              rebase from the specified changeset

       -b, --base
              rebase from the base of the specified changeset (up to greatest common ancestor of base and dest)

       -r, --rev
              rebase these revisions

       -d, --dest
              rebase onto the specified changeset

       --collapse
              collapse the rebased changesets

       -m, --message
              use text as collapse commit message

       -e, --edit
              invoke editor on commit messages

       -l, --logfile
              read collapse commit message from file

       --keep keep original changesets

       --keepbranches
              keep original branch names

       -D, --detach
              (DEPRECATED)

       -t, --tool
              specify merge tool

       -c, --continue
              continue an interrupted rebase

       -a, --abort
              abort an interrupted rebase

       --style
              display using template map file

       --template
              display with template

   record
       commands to interactively select changes for commit/qrefresh

   Commands
   qrecord
       hg qrecord [OPTION]... PATCH [FILE]...

       See hg help qnew & hg help record for more information and usage.

       If a list of files is omitted, all changes reported by hg status will be candidates for recording.

       See hg help dates for a list of formats valid for -d/--date.

       You  will  be  prompted  for whether to record changes to each modified file, and for files with multiple
       changes, for each change to use. For each query, the following responses are possible:

       y - record this change
       n - skip this change
       e - edit this change manually

       s - skip remaining changes to this file
       f - record remaining changes to this file

       d - done, skip remaining changes and files
       a - record all changes to all remaining files
       q - quit, recording no changes

       ? - display help

       This command is not available when committing a merge.

       Options:

       -A, --addremove
              mark new/missing files as added/removed before committing

       --close-branch
              mark a branch as closed, hiding it from the branch list

       --amend
              amend the parent of the working dir

       -s, --secret
              use the secret phase for committing

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

       -S, --subrepos
              recurse into subrepositories

       -w, --ignore-all-space
              ignore white space when comparing lines

       -b, --ignore-space-change
              ignore changes in the amount of white space

       -B, --ignore-blank-lines
              ignore changes whose lines are all blank

   relink
       recreates hardlinks between repository clones

   Commands
   relink
       hg relink [ORIGIN]

       When repositories are cloned locally, their data files will be hardlinked so that they only use the space
       of a single repository.

       Unfortunately, subsequent pulls into either repository will break hardlinks for any files touched by  the
       new changesets, even if both repositories end up pulling the same changes.

       Similarly, passing --rev to "hg clone" will fail to use any hardlinks, falling back to a complete copy of
       the source repository.

       This command lets you recreate those hardlinks and reclaim that wasted space.

       This  repository  will  be  relinked to share space with ORIGIN, which must be on the same local disk. If
       ORIGIN is omitted, looks for "default-relink", then "default", in [paths].

       Do not attempt any read operations on this repository while the command is  running.  (Both  repositories
       will be locked against writes.)

   schemes
       extend schemes with shortcuts to repository swarms

       This  extension  allows you to specify shortcuts for parent URLs with a lot of repositories to act like a
       scheme, for example:

       [schemes]
       py = http://code.python.org/hg/

       After that you can use it like:

       hg clone py://trunk/

       Additionally there is support for some more complex schemas, for example used by Google Code:

       [schemes]
       gcode = http://{1}.googlecode.com/hg/

       The syntax is taken from Mercurial templates, and you have unlimited number of variables,  starting  with
       {1}  and  continuing with {2}, {3} and so on. This variables will receive parts of URL supplied, split by
       /. Anything not specified as {part} will be just appended to an URL.

       For convenience, the extension adds these schemes by default:

       [schemes]
       py = http://hg.python.org/
       bb = https://bitbucket.org/
       bb+ssh = ssh://hg@bitbucket.org/
       gcode = https://{1}.googlecode.com/hg/
       kiln = https://{1}.kilnhg.com/Repo/

       You can override a predefined scheme by defining a new scheme with the same name.

   share
       share a common history between several working directories

   Commands
   share
       hg share [-U] SOURCE [DEST]

       Initialize a new repository and working directory that shares its history with another repository.

       Note   using rollback or extensions that destroy/modify history (mq, rebase, etc.) can cause considerable
              confusion with shared clones. In particular, if two shared clones are both  updated  to  the  same
              changeset,  and  one  of them destroys that changeset with rollback, the other clone will suddenly
              stop working: all operations will fail with "abort: working directory  has  unknown  parent".  The
              only  known  workaround  is  to use debugsetparents on the broken clone to reset it to a changeset
              that still exists.

       Options:

       -U, --noupdate
              do not create a working copy

   unshare
       hg unshare

       Copy the store data to the repo and remove the sharedpath data.

   shelve
       save and restore changes to the working directory

       The "hg shelve" command saves changes made to the working directory and reverts those changes,  resetting
       the working directory to a clean state.

       Later  on,  the  "hg unshelve" command restores the changes saved by "hg shelve". Changes can be restored
       even after updating to a different parent, in which case Mercurial's merge  machinery  will  resolve  any
       conflicts if necessary.

       You can have more than one shelved change outstanding at a time; each shelved change has a distinct name.
       For details, see the help for "hg shelve".

   Commands
   shelve
       hg shelve

       Shelving  takes  files  that  "hg  status"  reports  as not clean, saves the modifications to a bundle (a
       shelved change), and reverts the files so that their state in the working directory becomes clean.

       To restore these changes to the working directory, using "hg unshelve"; this will work even if you switch
       to a different commit.

       When no files are specified, "hg shelve" saves all not-clean files. If specific files or directories  are
       named, only changes to those files are shelved.

       Each shelved change has a name that makes it easier to find later.  The name of a shelved change defaults
       to  being  based on the active bookmark, or if there is no active bookmark, the current named branch.  To
       specify a different name, use --name.

       To see a list of existing shelved changes, use the --list option. For  each  shelved  change,  this  will
       print its name, age, and description; use --patch or --stat for more details.

       To delete specific shelved changes, use --delete. To delete all shelved changes, use --cleanup.

       Options:

       -A, --addremove
              mark new/missing files as added/removed before shelving

       --cleanup
              delete all shelved changes

       --date shelve with the specified commit date

       -d, --delete
              delete the named shelved change(s)

       -l, --list
              list current shelves

       -m, --message
              use text as shelve message

       -n, --name
              use the given name for the shelved commit

       -p, --patch
              show patch

       --stat output diffstat-style summary of changes

   unshelve
       hg unshelve [SHELVED]

       This  command  accepts an optional name of a shelved change to restore. If none is given, the most recent
       shelved change is used.

       If a shelved change is applied successfully, the bundle that contains  the  shelved  changes  is  deleted
       afterwards.

       Since you can restore a shelved change on top of an arbitrary commit, it is possible that unshelving will
       result  in  a  conflict between your changes and the commits you are unshelving onto. If this occurs, you
       must resolve the conflict, then use --continue to complete the unshelve operation. (The bundle  will  not
       be deleted until you successfully complete the unshelve.)

       (Alternatively,  you  can  use  --abort  to  abandon an unshelve that causes a conflict. This reverts the
       unshelved changes, and does not delete the bundle.)

       Options:

       -a, --abort
              abort an incomplete unshelve operation

       -c, --continue
              continue an incomplete unshelve operation

       --keep keep shelve after unshelving

   strip
       strip changesets and their descendents from history

       This extension allows you to strip changesets and all their descendants  from  the  repository.  See  the
       command help for details.

   Commands
   strip
       hg strip [-k] [-f] [-n] [-B bookmark] [-r] REV...

       The  strip  command  removes the specified changesets and all their descendants. If the working directory
       has uncommitted changes, the operation is aborted unless the --force flag  is  supplied,  in  which  case
       changes will be discarded.

       If  a  parent  of  the  working  directory  is stripped, then the working directory will automatically be
       updated to the most recent available ancestor of the stripped parent after the operation completes.

       Any stripped changesets are stored in .hg/strip-backup as a  bundle  (see  hg  help  bundle and  hg  help
       unbundle).  They  can  be  restored  by  running hg unbundle .hg/strip-backup/BUNDLE, where BUNDLE is the
       bundle file created by the strip. Note that the local revision numbers will in general be different after
       the restore.

       Use the --no-backup option to discard the backup bundle once the operation completes.

       Strip is not a history-rewriting operation and can be used on changesets in the public phase. But if  the
       stripped changesets have been pushed to a remote repository you will likely pull them again.

       Return 0 on success.

       Options:

       -r, --rev
              strip specified revision (optional, can specify revisions without this option)

       -f, --force
              force removal of changesets, discard uncommitted changes (no backup)

       -b, --backup
              bundle  only  changesets  with local revision number greater than REV which are not descendants of
              REV (DEPRECATED)

       --no-backup
              no backups

       --nobackup
              no backups (DEPRECATED)

       -n     ignored  (DEPRECATED)

       -k, --keep
              do not modify working copy during strip

       -B, --bookmark
              remove revs only reachable from given bookmark

   transplant
       command to transplant changesets from another branch

       This extension allows you  to  transplant  changes  to  another  parent  revision,  possibly  in  another
       repository. The transplant is done using 'diff' patches.

       Transplanted  patches  are  recorded in .hg/transplant/transplants, as a map from a changeset hash to its
       hash in the source repository.

   Commands
   transplant
       hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...

       Selected changesets will be applied on top of the current working directory with the log of the  original
       changeset. The changesets are copied and will thus appear twice in the history with different identities.

       Consider  using  the  graft  command if everything is inside the same repository - it will use merges and
       will usually give a better result.  Use the rebase extension if the changesets are  unpublished  and  you
       want to move them instead of copying them.

       If --log is specified, log messages will have a comment appended of the form:

       (transplanted from CHANGESETHASH)

       You  can  rewrite  the changelog message with the --filter option.  Its argument will be invoked with the
       current changelog message as $1 and the patch as $2.

       --source/-s specifies another repository to use for selecting changesets, just as if it  temporarily  had
       been  pulled.   If  --branch/-b  is  specified, these revisions will be used as heads when deciding which
       changesets to transplant, just as if only these revisions had been pulled.  If --all/-a is specified, all
       the revisions up to the heads specified with --branch will be transplanted.

       Example:

       • transplant all changes up to REV on top of your current revision:

         hg transplant --branch REV --all

       You can optionally mark selected transplanted changesets as merge changesets. You will not be prompted to
       transplant any ancestors of a merged transplant, and you can merge descendants of them  normally  instead
       of transplanting them.

       Merge  changesets  may  be  transplanted directly by specifying the proper parent changeset by calling hg
       transplant --parent.

       If no merges or revisions are provided, hg transplant will start an interactive changeset browser.

       If a changeset application fails, you can fix the merge by hand and then resume where  you  left  off  by
       calling hg transplant --continue/-c.

       Options:

       -s, --source
              transplant changesets from REPO

       -b, --branch
              use this source changeset as head

       -a, --all
              pull all changesets up to the --branch revisions

       -p, --prune
              skip over REV

       -m, --merge
              merge at REV

       --parent
              parent to choose when transplanting merge

       -e, --edit
              invoke editor on commit messages

       --log  append transplant info to log message

       -c, --continue
              continue last transplant session after fixing conflicts

       --filter
              filter changesets through command

   win32mbcs
       allow the use of MBCS paths with problematic encodings

       Some  MBCS  encodings are not good for some path operations (i.e.  splitting path, case conversion, etc.)
       with its encoded bytes. We call such a encoding (i.e. shift_jis  and  big5)  as  "problematic  encoding".
       This extension can be used to fix the issue with those encodings by wrapping some functions to convert to
       Unicode string before path operation.

       This extension is useful for:

       • Japanese Windows users using shift_jis encoding.

       • Chinese Windows users using big5 encoding.

       • All users who use a repository with one of problematic encodings on case-insensitive file system.

       This extension is not needed for:

       • Any user who use only ASCII chars in path.

       • Any user who do not use any of problematic encodings.

       Note that there are some limitations on using this extension:

       • You should use single encoding in one repository.

       • If the repository path ends with 0x5c, .hg/hgrc cannot be read.

       • win32mbcs is not compatible with fixutf8 extension.

       By  default,  win32mbcs  uses  encoding.encoding  decided  by Mercurial.  You can specify the encoding by
       config option:

       [win32mbcs]
       encoding = sjis

       It is useful for the users who want to commit with UTF-8 log message.

   win32text
       perform automatic newline conversion

          Deprecation: The win32text extension requires each user to configure the extension again and again for
          each clone since the configuration is not copied when cloning.

          We have therefore made the eol as an alternative. The eol uses  a  version  controlled  file  for  its
          configuration and each clone will therefore use the right settings from the start.

       To perform automatic newline conversion, use:

       [extensions]
       win32text =
       [encode]
       ** = cleverencode:
       # or ** = macencode:

       [decode]
       ** = cleverdecode:
       # or ** = macdecode:

       If not doing conversion, to make sure you do not commit CRLF/CR by accident:

       [hooks]
       pretxncommit.crlf = python:hgext.win32text.forbidcrlf
       # or pretxncommit.cr = python:hgext.win32text.forbidcr

       To do the same check on a server to prevent CRLF/CR from being pushed or pulled:

       [hooks]
       pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
       # or pretxnchangegroup.cr = python:hgext.win32text.forbidcr

   zeroconf
       discover and advertise repositories on the local network

       The zeroconf extension will advertise hg serve instances over DNS-SD so that they can be discovered using
       the hg paths command without knowing the server's address.

       To allow other people to discover your repository using run hg serve in your repository:

       $ cd test
       $ hg serve

       You can discover Zeroconf-enabled repositories by running hg paths:

       $ hg paths
       zc-test = http://example.com:8000/test

FILES

       /etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc

              This  file  contains defaults and configuration. Values in .hg/hgrc override those in $HOME/.hgrc,
              and these override settings made in the global /etc/mercurial/hgrc configuration.  See hgrc(5) for
              details of the contents and format of these files.

       .hgignore

              This file contains regular expressions (one per line) that describe  file  names  that  should  be
              ignored by hg. For details, see hgignore(5).

       .hgsub

              This  file  defines  the  locations  of  all  subrepositories,  and  tells where the subrepository
              checkouts came from. For details, see hg help subrepos.

       .hgsubstate

              This file is where Mercurial stores all nested repository states. NB:  This  file  should  not  be
              edited manually.

       .hgtags

              This file contains changeset hash values and text tag names (one of each separated by spaces) that
              correspond to tagged versions of the repository contents. The file content is encoded using UTF-8.

       .hg/last-message.txt

              This file is used by hg commit to store a backup of the commit message in case the commit fails.

       .hg/localtags

              This  file  can  be  used  to  define local tags which are not shared among repositories. The file
              format is the same as for .hgtags, but it is encoded using the local system encoding.

       Some commands (e.g. revert) produce backup files ending in .orig, if the .orig file already exists and is
       not tracked by Mercurial, it will be overwritten.

BUGS

       Probably lots, please post them to the mailing list (see Resources below) when you find them.
