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

       -R, --repository
              repository root directory or name of overlay bundle file

       --cwd  change working directory

       -y, --noninteractive

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:

       Returns 0 on success.

       Options:

       -p, --strip
              directory strip option for patch. This has the same meaning  as  the  corresponding

              aliases: patch

   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
              a remote changeset intended to be added

       -B, --bookmarks
              compare bookmarks

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

       -p, --patch

       -g, --git
              use git extended diff format

       -l, --limit
              limit number of changes displayed

              do not show merges

       --stat output diffstat-style summary of changes

       -G, --graph
              show the revision DAG

       --style

       --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)

              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.

       --removed
              include revisions where files were removed

       -m, --only-merges
              show only merges (DEPRECATED)

       -u, --user
              revisions committed by user

       --only-branch
              show only changesets within the given named branch (DEPRECATED)

       -b, --branch

              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

       -B, --bookmarks

              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

       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

       -f, --force
              remove (and delete) file even if added or modified

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

              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

   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

              aliases: st

   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

              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

   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.

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:

              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".

              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.

              timezone offset).

       isodate
              Date. Returns the date in ISO 8601 format: "2009-08-18 13:00 +0200".

              +0200". See also the rfc3339date filter.

       localdate
              Date. Converts a date to local date.

       nonempty
              Any text. Returns '(none)' if the string is empty.

              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".

              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

   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 XMLRPC and email interfaces.

              3.0

                     MySQL access, Bugzilla 3.0 and later.

              2.18

                     MySQL access, Bugzilla 2.18 and up to but not including 3.0.

              2.16

                     MySQL access, Bugzilla 2.16 and up to but not including 2.18.

       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.

       bugzilla.user
              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

       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".

   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

       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.

   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
       # Make sure to set email.from if you do this.
       #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

       [web]
       # If you want hyperlinks (optional)
       baseurl = http://server/path/to/repo

   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
              do not update the new working directories

       --uncompressed

              location of source patch repository

       -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)

   qcommit

              recurse into subrepositories

              aliases: qci

   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)

              aliases: qremove qrm

   qdiff
       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.

       Options:

       -a, --text
              treat all files as text

       -g, --git
              use git extended diff format

              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

              include names matching the given patterns

       -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

       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:

       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

   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

       --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

              add/update author field in patch with given user

       -D, --currentdate
              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:

       -c, --copy
              copy patch directory

       -n, --name
              copy directory name

       -e, --empty
              clear queue status file

       -f, --force

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   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

       --pop  pop to before first guarded applied patch

       --reapply
              pop, then reapply patches

   qseries
       hg qseries [-ms]

       Returns 0 on success.

       -1, --first
              show only the first patch

       -s, --summary
              print first line of patch header

   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.

   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.

   record
       hg record [OPTION]... [FILE]...

       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.
