NAME

       tla - arch command line client tool

SYNOPSIS

       tla command [ command_options ]
       tla command [-h|--help|-H]
       tla [-h|--help|-H|-V|--version]

DESCRIPTION

       tla is an implementation of arch .

       arch  is  a  version  control  system,  which allows you to keep old versions of files and
       directories (usually source code), keep a log of who,  when,  and  why  changes  occurred,
       etc., like SVN, CVS, or RCS.

       arch has a number of advantages compared to competing systems. Among these are:

   Works on Whole Trees
       arch  keeps track of whole trees -- not just individual files.  For example, if you change
       many files in a tree, arch can record  all  of  those  changes  as  a  group  rather  than
       file-by-file;  if  you  rename  files  or  reorganize  a  tree, arch can record those tree
       arrangements along with your changes to file contents.

   Changeset Oriented
       arch doesn´t simply "snapshot" your project trees.  Instead, arch associates each revision
       with  a  particular  changeset:  a description of exactly what has changed.  arch provides
       changeset oriented commands to  help  you  review  changesets,  merge  trees  by  applying
       changesets,  examine  the history of a tree by asking what changesets have been applied to
       it, and so forth.

   Fully Distributed
       arch doesn´t rely on a central repository.  For example, there is no need  to  give  write
       access  to  a project´s archive to all significant contributors. Instead, each contributor
       can have their own archive for  their  work.   arch  seamlessly  operates  across  archive
       boundaries.

HELP

   tla help
       provide help with arch

       Usage: tla help [options]

         -h, --help     Display a help message and exit.
         -H             Display a verbose help message and exit.
         -b, --basic    Display basic commands only
         -V, --version  Display a release identifier string
                        and exit.

       This command prints a list of the available commands.

       To see just a list of the options to a particular command, use:

           tla $cmd -h

       (where $cmd is the name of the  command).    For  additional  explanation  about  a  given
       command, use:

           tla $cmd -H

USER COMMANDS

   tla my-id
       print or change your id

       Usage: tla my-id [options] [id]

         -h, --help     Display a help message and exit.
         -H             Display a verbose help message and exit.
         -V, --version  Display a release identifier string
                        and exit.
         -e, --errname  specify program name for errors
         -u, --uid      print only the UID portion of the ID

       With no argument print your arch id.

       With an argument, record ID-STRING as your id in ~/.arch-params/=id

       Your id is recorded in various archives and log messages as you use arch.  It must consist
       entirely of printable characters and fit on one line.  By convention, it should  have  the
       form of an email address, as in this example:

               Jane Hacker <jane.hacker@gnu.org>

       The  portion of an id string between < and > is called your uid.  arch sometimes uses your
       uid as a fragment when generating unique file names.

       The option -u (--uid) causes only the uid part of your id string to be printed.

   tla my-default-archive
       print or change your default archive

       Usage: tla my-default-archive [options] [archive]

         -h, --help     Display a help message and exit.
         -H             Display a verbose help message and exit.
         -V, --version  Display a release identifier string
                        and exit.
         -A, --archive  Override `my-default-archive´
         -e, --errname  specify program name for errors
         -d, --delete   unspecify your default archive
         -s, --silent   suppress reassuring messages

       With no argument, and without -d, print the name of your default archive.

       With    an    argument,    record    ARCHIVE    as     your     default     archive     in
       ~/.arch-params/=default-archive

       With  the  option  -d  (--delete)  and  no argument, ensure that you do not have a default
       archive set in ~/.arch-params.

       Your default archive is determined this way:

       If the option -A (--archive) is given and not empty, that archive is  the  default  (which
       makes this script useful for processing a -A argument that was passed to another script).

       If  -A  is not given, but ~/.arch-params/=default-archive exists and is not empty, that is
       your default archive.

       Otherwise, your default archive is the name of the local archive rooted at the argument to
       -R (--root) or specified in the environment variable ARCHROOT.

       If no default archive can be found by any of these means, the program exits with status 1,
       printing an error message unless the -s (--silent) option is given.

   tla register-archive
       change an archive location registration

       Usage: tla register-archive [options] [archive] location

         -h, --help        Display a help message and exit.
         -H                Display a verbose help message and exit.
         -V, --version     Display a release identifier string
                           and exit.
         -f, --force       overwrite existing location
         --present-ok      return 0 even if archive exists
         -d, --delete      delete archive registration

       Record the location of ARCHIVE.

       With -d, remove the registration of a previously registered archive.  When accompanied  by
       -f, override permissions on the registration file and don´t complain if the archive is not
       registered.

       A LOCATION should be either a directory name or a distant URL.

       When registering a new archive, if no ARCHIVE´s name is passed on the command  line,  then
       the archive´s name will be read automatically from the archive´s meta data.

       Archive locations are stored in ~/.arch-params/=locations.

       You  must  register  the  location  of  a  remote archive before you access it.  It is not
       strictly necessary to register the locations of local archives  (you  can  always  specify
       their location using command line arguments and/or environment variables), but registering
       local archive locations is recommend (for simplicity).

   tla whereis-archive
       print an archive location registration

       Usage: tla whereis-archive [options] archive

         -h, --help     Display a help message and exit.
         -H             Display a verbose help message and exit.
         -V, --version  Display a release identifier string
                        and exit.

       Print the registered location of an archive.

       Usually the archive must have been previously registered with "tla register-archive".

       As a special exception, the the archive is not registered, but is the name of the  archive
       rooted  at  the  location given with the option -R (--root) or in the environment variable
       ARCHROOT then print that root directory.

   tla archives
       report registered archives and their locations

       Usage: tla archives [options] [search regular expression]

         -h, --help            Display a help message and exit.
         -H                    Display a verbose help message and exit.
         -V, --version         Display a release identifier string
                               and exit.
         -n, --names           print archive names only
         -R, --exclude-remote  Exclude MIRROR and SOURCE archives.

       Print a list of registered archives and their locations

       If [search regex] is given then only archives with names that match [search regex] will be
       shown

PROJECT TREE COMMANDS

   tla init-tree
       initialize a new project tree

       Usage: tla init-tree [options] [[archive]/version]

         -A, --archive  Override `my-default-archive´
         -d, --dir DIR  cd to DIR first
         --nested       initialize a nested project tree.

       Initialize DIR as a new project tree.

       An  empty  patch-log  for  VERSION  will  be created, and VERSION will be made the default
       location for check-ins.

   tla tree-root

         -s, --silent    exit status only

       Find and print the root of the project tree that contains DIR (or the current  directory).
       The option --accurate checks for three possibilities:

           1) The project tree was the subject of a commit that
              was killed before the log entry was added to the
              tree´s patch log.  It is unknown whether or not
              the commit took place in the archive.  The {arch}
              directory contains the log file as "++mid-commit".

           2) The project tree was the subject of a killed commit, but
              it is certain the commit took place.  The log file
              is stored as "++commit-definite".

           3) The project tree patch log is fully up-to-date (as far as
              arch knows).

       In case 1, exit with an error and error message.

       In case 2, install the log file before printing the tree root and exiting normally.

       In case 3, print the tree root and exit normally.

         --unescaped             show filenames in unescaped form

       Compute a patch set describing the changes from REVISION to the  project  tree  containing
       DIR.   Save  the  patch in PATCH-DIR (which must not already exist) and apply the patch in
       reverse to the project tree containing DIR.

       The effect is to remove local changes  in  the  DIR  project  tree  but  save  them  in  a
       convenient form.

       If  REVISION  is not specified, the latest ancestor of the default version of project tree
       is used.

       If REVISION is specified as a VERSION, the latest ancestor of the  project  tree  in  that
       VERSION is used.

       If DIR is not specified, "." is assumed.

       If PATCH-DIR is not specified, a temporary file-name of the matching ,,undo-* is used.

       If --no-output is specified, the patch set is not saved.

         -q, --quiet      no progress reports while computing changeset
         -d, --dir DIR    Operate on project tree in DIR (default `.´)
         --unescaped      show filenames in unescaped form

       Apply CHANGESET to the project tree and then delete CHANGESET.

       If CHANGESET is not specified, the highest numbered ,,undo-N directory in the project tree
       root is used.

       If --keep is given, the changeset directory is not deleted.

       If a directory is precious, junk, or unrecognized,  only  the  directory  name  itself  is
       printed -- its contents are not searched.

       Each  command  option  implies  the corresponding category option (e.g. "--source-command"
       implies "--source").  The exit status of the command is ignored.

   tla tree-lint
       (alias for lint)

       Usage: tla tree-lint [options] [dir]

         -h, --help                Display a help message and exit.

       matching recognized naming conventions.

       The  default  is to list files failing any of those tests.  Enabling any of the `specific´
       tests disables the rest, unless they´re explicitly enabled on the command line. Therefore,
       "tla tree-lint" is equivalent to "tla tree-lint -sutmd"

   tla lint

         -d, --duplicate-ids       Just list duplicated ids
         --strict                  exit with non-0 status on _any_ oddity
         --unescaped               show filenames in unescaped form

       Audit  a  source  tree  for  missing  files,  untagged files, duplicate ids, and files not
       matching recognized naming conventions.

       The default is to list files failing any of those tests.  Enabling any of  the  `specific´
       tests disables the rest, unless they´re explicitly enabled on the command line. Therefore,
       "tla tree-lint" is equivalent to "tla tree-lint -sutmd"

       Print or change the method by which source files are identified in  DIR  (or  the  current
       directory).

       When setting, METHOD must be one of:

               names           -- use naming conventions only
               implicit        -- use naming conventions but permit
                                  for inventory tags

         -V, --version    Display a release identifier string
                          and exit.
         -D, --dir DIR    cd to DIR first
         -d, --delete     remove the default
         -s, --strong     use the strong default (default)
         -w, --weak       use the weak default
         --dont-care      use the dont-care default

       For files in this directory, use:

            ID-PREFIX__BASENAME

       as the default explicit id for all files in this directory that do not  have  an  explicit
       explicit id.

       With no arguments, print the previously set ID-PREFIX.

       By  default, this command sets, prints or deletes a "strong default" -- a default explicit
       id which overrides implicit ids.

       With --weak, set (or print) a weak default id which is overridden by explicit ids.

       The --dont-care option sets (or with -d, clears) a flag for  that  directory  that  causes
       unidged files not to be reported as such in "tla tree-lint" reports.

   tla default-id
       (alias for explicit-default)

       Usage: tla default-id [options] [TAG-PREFIX]

         -h, --help       Display a help message and exit.

         -s, --strong     use the strong default (default)
         -w, --weak       use the weak default
         --dont-care      use the dont-care default

       For files in this directory, use:

            ID-PREFIX__BASENAME

       as  the  default  explicit id for all files in this directory that do not have an explicit
       explicit id.

       With no arguments, print the previously set ID-PREFIX.

       By default, this command sets, prints or deletes a "strong default" -- a default  explicit
       id which overrides implicit ids.

       With --weak, set (or print) a weak default id which is overridden by explicit ids.

       The  --dont-care  option  sets  (or with -d, clears) a flag for that directory that causes
       unidged files not to be reported as such in "tla tree-lint" reports.

   tla id-tagging-defaults
       print the default =tagging-method contents

       Usage: tla id-tagging-defaults [options]

ARCHIVE TRANSACTION COMMANDS

   tla make-archive
       create a new archive directory

       Usage: tla make-archive [options] [name] location

         -h, --help                       Display a help message and exit.
         -H                               Display a verbose help message and exit.
         -V, --version                    Display a release identifier string
                                          and exit.
         -m, --mirror MASTER              create mirror of specified archive
         -M, --mirror-from MASTER-SOURCE  create pull-based mirror of specified archive
         -l, --listing                    Keep .listing files up-to-date in this archive.
         -t, --tla                        Create a tla format archive.
         -b, --baz                        Create a baz format archive (the default).
         -s, --signed                     GPG sign the contents of this archive.

       NAME is the global name for the archive.  It  must  be  an  email  address  with  a  fully
       qualified  domain  name,  optionally  followed  by  "--"  and a string of letters, digits,
       periods and dashes.

       With --mirror, label the new archive as a mirror of MASTER. Ordinary commits  can  not  be
       made to a mirror archive, however the command "tla archive-mirror" can write to a mirror.

       Two special forms of this command are available:

          tla make-archive --mirror MASTER LOCATION

       is equivalent to:

          tla make-archive --mirror MASTER MASTER-MIRROR LOCATION

       and  thus  "tla  archive-mirror MASTER" will push changes from MASTER to the newly created
       mirror.

          tla make-archive --mirror-from MASTER-SOURCE LOCATION

       is equivalent to:

          tla make-archive --mirror MASTER-SOURCE MASTER LOCATION

       and thus "tla archive-mirror MASTER" will pull changes from  MASTER-SOURCE  to  the  newly
       created mirror.

       The  first of these two special forms is especially handy when creating a remote mirror in
       which to publish a local repository.

       The second special form is handy when creating a local mirror of a remote archive, locally
       bound to the remote archive´s name.

       The --tla option creates a tla format archive, the default is  to create a Bazaar archive.

   tla archive-setup
       create new categories, branches and versions

       Usage: tla archive-setup [options] [version ...]

         -h, --help       Display a help message and exit.
         -H               Display a verbose help message and exit.
         -V, --version    Display a release identifier string
                          and exit.
         -A, --archive    Override `my-default-archive´
         -f, --file FILE  read the list of desired versions from FILE
         -b, --branches   make base-0 tags
         -c, --cache      archive cache when creating base-0 tags

       Given  a  list  of  categories,  branches,  and  versions,  ensure that these exist in the
       appropriate archive.

       For example, starting with an empty archive,:

           % tla archive-setup  proja--devo--1.0 projb

       creates a category, branch, and version for project A, and a category for project B

       When the --file option is used, the list of items to create is read from a file  (use  "-"
       to indicate standard input).

       With  the  --file  option, the option --branches may be provided.  In this case, the input
       should have two items per line:  a target version (to create), and  a  source  version  to
       build a tag from.   For example, given an input file containg:

           proja--devo--1.0  his@foo.com/proja--devo--1.0

       with --branches, archive-setup creates a proja version in your default archive, and adds a
       base-0 revision to that project which is a tag of the  latest  revision  in  his@foo.com´s
       archive.   (This  can  make  it quite easy to set-up a new archive which contains branches
       from existing archives, for example.)

       If --branches is used, the --cache option may also be used.   It causes  each  new  base-0
       revision to be archive-cached (see "tla cacherev -H")

         -l, --log FILE          Commit with log file FILE.
         -s, --summary TEXT      log with summary TEXT plus log-for-merge output
         -L, --log-message TEXT  log with TEXT
         -S, --setup             Use `archive-setup´ if necessary; implied by default.

         --unescaped             show filenames in unescaped form

       Archive  a  from-scratch  base revision of the project tree containing DIR (or the current
       directory).  Use this command to create the first revision of a new project.

       Extract  REVISION  from  an  archive,  creating  the new project tree DIR.   If DIR is not
       specified, store the working copy in a subdirectory of the current  directory,  giving  it
       the  name  of  the  revision.  CAUTION:  when  using  the  links  option  be  sure  to use
       copy-on-write on your editor or the revision library will be corrupted.  Either  way,  the
       project tree must not already exist.

         -b, --break    break any existing lock

       Acquire the lock needed to create REVISION.

       Revision must be the  next  patch-level  in  sequence,  however,  if  no  patch  level  is
       specified,  the  lock  is  taken  unconditionally.  If no version is specified, the latest
       version is locked.

   tla archive-mirror
       update an archive mirror

       Usage: tla archive-mirror [options] [from [to] [limit]]

         -h, --help         Display a help message and exit.

         --cached-tags      copy only cachedrevs for tags to other archives

       If no arguments are  given,  update  your  `my-default-archive´-MIRROR  archive  with  the
       contents of `my-default-archive´.

       If  a  [FROM]  archive is given, update the [FROM]-MIRROR archive with the contents of the
       [FROM] archive

       If both [FROM] and [TO] archives are specified, update [TO] with the contents of [FROM]

       If LIMIT is provided, it should be a category, branch, version, or revision  name.    Only
       the  indicated  part  of  FROM  will  be copied to TO. If LIMIT is a revision, then cached
       revisions will be copied and deleted to TO.

       (see "tla make-archive -H".).

       where each pair indicates that at patch level  INTO-RVN  of  INTO,  the  patch  log  entry
       FROM-RVN was added.

       FROM  may  be  a branch name, version name, or revision name. If a branch or version name,
       all merges from that branch or version are reported.  If a revision name, only  the  merge
       points for that specific revision are reported.

       INTO  may  be a version name or revision name.  If a version name, all merge points within
       that version are printed.  If a revision name,  all  merge  points  at  that  revision  or
       earlier are printed.

       Output is sorted using patch-level ordering of the first column.

       Included  patches  are  listed  by full name unless FROM is a revision name.  If FROM is a
       revision, --full causes its full name to be printed.

       with VERSION.

MULTI-PROJECT CONFIGURATION COMMANDS

   tla build-config
       instantiate a multi-project config

       Usage: tla build-config [options] config

         -h, --help          Display a help message and exit.
         -H                  Display a verbose help message and exit.
         -V, --version       Display a release identifier string
                             and exit.
         -d, --dir DIR       cd to DIR first
         --no-pristines      don´t create pristine copies
         --link              hardlink files to revision library instead of copying
         --library           ensure revisions are in the revision library
         --sparse            add library entries sparsely (--link, --library)
         -r, --release-id    overwrite ./=RELEASE-ID for this config

       Build the named configuration.  See also "tla cat-config -H".

   tla cat-config
       output information about a multi-project config

       Usage: tla cat-config [options] config

         -h, --help        Display a help message and exit.
         -H                Display a verbose help message and exit.
         -V, --version     Display a release identifier string
                           and exit.
         -d, --dir DIR     cd to DIR first
         -o, --output CFG  write the output as config CFG
         -f, --force       overwrite an exiting config (with --output)
         -s, --snap        Show current patch levels of subtree packages.
         --unescaped       show filenames in unescaped form

       Parse and print the indicate config file from a project tree

       A  config  file  contains  blank  lines,  comment  lines  starting  with  "#",  and config
       specification lines.   The config file called  $NAME  is  stored  in  a  project  tree  as
       ./configs/$NAME or as ./$NAME.

       A  config  specification  line  contains  a  relative  path  within  a project tree, and a
       specification of the project or revision to store in that location.

       For example, the line:

          ./src/arch   lord@emf.net--2003b/arch--devo--1.0

       means that, when building the configuration, the latest revision of arch--devo--1.0 should
       be created within the tree as ./src/arch.

       The  project  specification  can  be a branch name, version name or the name of a specific
       revision.

       The option --snap says to examine  the  project  tree  to  find  out  which  revisions  of
       configured  project  are  printed, and generate a new config specification that references
       those specific revisions.   For example, the output for the line shown above might be:

           ./src/arch  lord@emf.net--2003b/arch--devo--1.0--patch-21

       The option --output causes  the  output  from  this  command  to  be  recorded  as  a  new
       configuration file (or to replace an existing file if --force is provided).

COMMANDS FOR BRANCHING AND MERGING

   tla tag
       create a continuation revision

       Usage: tla tag [options] SOURCE-REVISION TAG-VERSION

         -h, --help         Display a help message and exit.
         -H                 Display a verbose help message and exit.
         -V, --version      Display a release identifier string
                            and exit.
         -A, --archive      Override `my-default-archive´
         -l, --log FILE     commit with log file FILE
         --no-cacherev      Do not cacherev tag even if different archive

         --no-setup         Do not use `archive-setup´ even if necessary.

       Create  the continuation revision TAG-VERSION (branch point or tag) which is equivalent to
       SOURCE-REVISION (plus a log entry).

       If no log entry is provided, a trivial log entry will be created.

   tla branch
       create a continuation revision

       Usage: tla branch [options] [SOURCE] BRANCH

         -h, --help         Display a help message and exit.

         --fix              create a versionfix revision

       Create the continuation revision BRANCH (branch point  or  tag)  which  is  equivalent  to
       SOURCE  (plus  a  log  entry).  If  no  log entry is provided, a trivial log entry will be
       created.

       If SOURCE is not specified, the current project tree revision is used,   and  the  project
       tree is switched to BRANCH

   tla switch
       change the working trees version

       Usage: tla switch [options] [package]

         -h, --help     Display a help message and exit.
         -H             Display a verbose help message and exit.

         -A, --archive  Override `my-default-archive´.
         -d, --dir DIR  Change to DIR first.
         -q, --quiet    Suppress progress information

       change  the  working  trees  version  to that of package, and make equivalent to revision.
       Preserves uncommitted changes.

       Note: tla automatically switches to the _latest_ revision in the supplied version.

   tla update
       update a project tree

       Usage: tla update [options] [version/revision]

         -h, --help       Display a help message and exit.
         -H               Display a verbose help message and exit.
         -V, --version    Display a release identifier string
                          and exit.
         -A, --archive    Override `my-default-archive´
         -d, --dir DIR    Update project tree in DIR (default `.´)
         -N, --forward    pass the --forward option to `patch´
         --dest DEST      Instead of modifying the project tree in-place,
                          make a copy of it to DEST and apply the result to that
         --unescaped      show filenames in unescaped form

       Update a project tree by getting the latest revision of VERSION (or the default version of
       the  project  tree)  and  then applying a patch set of the differences between the project
       tree and the highest revision with which it is up-to-date.

       If the merge involves conflicts, a warning message is printed, and the  new  project  tree
       will contain ".rej" files.

   tla replay
       apply revision changesets to a project tree

       Usage: tla replay [options] [version/revision...]

         -h, --help          Display a help message and exit.
         -H                  Display a verbose help message and exit.
         -V, --version       Display a release identifier string
                             and exit.
         -A, --archive       Override `my-default-archive´
         --list FILE         read a list of patches to apply
         --new               replay only new patches
         --reverse           reverse the named patch
         -N, --forward       pass the --forward option to `patch´
         -d, --dir DIR       Operate on project tree in DIR (default `.´)
         --dest DEST         Instead of modifying the project tree in-place,
                             make a copy of it to DEST and apply the result to that
         --skip-present      skip patches that contain 1 or more patch logs already in this tree
         --unescaped         show filenames in unescaped form

       The result is formed by applying patches in the latest revision of VERSION (or the default
       version of the project tree), stopping after the first patch that  causes  conflicts.   If
       multiple VERSIONs are specified, they are applied in turn.

       If  one  or  more  specific  REVISIONs (including patch-levels) is specified instead, only
       those patch sets, and no others, will be applied.

       With the --list option, read a list of patches to apply from FILE (- for standard  input).
       Complete  revision  names  should  be listed, one per line.  replay will stop at the first
       patch in the list that causes a merge conflict, leaving behind files  with  names  of  the
       form:

          ,,replay.conflicts-in --  the name of the patch that caused conflicts

          ,,replay.remaining    --  the list of patches not yet applied

   tla star-merge
       merge mutually merged branches

       Usage: tla star-merge [options] [FROM]

         -h, --help               Display a help message and exit.
         -H                       Display a verbose help message and exit.
         -V, --version            Display a release identifier string
                                  and exit.
         -A, --archive            Override tree archive
         -c, --changes OUTPUT     Generate but don´t apply the changeset.
         -r, --reference VERSION  Set reference version (default: project tree version)
         -N, --forward            pass the --forward option to `patch´
         -t, --three-way          Perform a 3-way (diff3-style) merge.
         -d, --dir DIR            Operate on project tree in DIR (default `.´)
         --unescaped              show filenames in unescaped form

       Merge  changes  from  FROM  into  the  project  tree, considering common ancestry from the
       project tree reference version, REFERENCE (which defaults  to  the  tree  version  of  the
       project tree). If FROM is not given, it defaults to the tree revision.

       The  purpose  of this command is to merge changes between development lines which may have
       merged in both directions.   It uses merge history to attempt  to  minimize  the  spurious
       conflicts that can arise from `mutual merging´.

       FROM  indicates  a  revision (it may be specified as a version name, indicating the latest
       revision in that version).

       TREE is the project tree into which the merge will occur.

       Star-merge works by computing the most recent ANCESTOR revision of REFERENCE and FROM  and
       then applying the changeset:

                delta (ANCESTOR, FROM)

       to TREE.

       The "most recent ancestor" is defined as follows:

       MAYBE_ANCESTOR_1 is defined as the highest patch level of FROM in REFERENCE for which both
       TREE and FROM have a patch log. In other words, it is the  latest  REFERENCE  revision  of
       FROM´s version already merged into TREE.

       MAYBE_ANCESTOR_2  is  defined  as the highest patch level in REFERENCE for which both FROM
       and REFERENCE have a patch log.  In other words, it is the latest  revision  of  REFERENCE
       already merged into FROM.

       MAYBE_ANCESTOR_2,  if  it  is  not  "nil", was merged into FROM at some revision of FROM´s
       version, which we can call LAST_MERGE_INTO_FROM.

       If both MAYBE_ANCESTOR_1 or MAYBE_ANCESTOR_2 are nil, star-merge can do nothing.

       If just one of MAYBE_ANCESTOR_1 is MAYBE_ANCESTOR_2 is not nil, then that non-nil value is
       ANCESTOR.

       If  both  MAYBE_ANCESTOR_1 and MAYBE_ANCESTOR_2 are not nil, then LAST_MERGE_INTO_FROM and
       MAYBE_ANCESTOR_1 are compared (both are revisions in FROM´s version). If  MAYBE_ANCESTOR_1
       is  the  later revision, then MAYBE_ANCESTOR_1 is ANCESTOR, otherwise, MAYBE_ANCESTOR_2 is
       ANCESTOR.

   tla apply-delta
       compute a changeset between any two trees or revisions and apply it to a project tree

       Usage: tla apply-delta [options] FROM(REVISION|DIR) TO(REVISION|DIR)

         -h, --help       Display a help message and exit.
         -H               Display a verbose help message and exit.
         -V, --version    Display a release identifier string
                          and exit.
         -A, --archive    Override `my-default-archive´
         -N, --forward    pass the --forward option to `patch´
         --cache DIR      specify a cache root for pristine copies
         -d, --dir DIR    Operate on project tree in DIR (default `.´)
         --dest DEST      Instead of modifying the project tree in-place,
                          make a copy of it to DEST and apply the result to that
         --unescaped      show filenames in unescaped form

       A delta between A and B (both of which may be either a full revision or a project tree) is
       computed, and then applied to the project tree.

       Exit Status Codes:

           0  No conflict during patch
           1  Conflicts occurred during patch
           3  Internal Error

   tla missing
       print patches missing from a project tree

       Usage: tla missing [options] [version]

         -h, --help          Display a help message and exit.
         -H                  Display a verbose help message and exit.
         -V, --version       Display a release identifier string
                             and exit.
         -A, --archive       Override `my-default-archive´
         -q, --quiet         produce no ordinary output
         -x, --exit-status   exit non-0 if patches are missing
         -d, --dir DIR       cd to DIR first
         -r, --reverse       sort from newest to oldest
         -s, --summary       display a summary of each missing patch
         -c, --creator       display the creator of each missing patch
         -D, --date          display the date of each missing patch
         -f, --full          print full revision names
         --merges            print a merge list for each missing patch
         --skip-present      skip patches that contain 1 or more patch logs already in this tree

       Print  a  list  of  patches  missing  in  the  project tree containing DIR (or the current
       directory) for VERSION (or the default version. of the project tree).

       The flag --merges means, for each patch, to print the list  of  patches  included  in  the
       patch in two columns.  For example:

               PATCH-A        PATCH-A
               PATCH-A        PATCH-B
               PATCH-A        PATCH-C

       means that PATCH-A includes the changes from PATCH-B and PATCH-C. (Every patch includes at
       least itself.)

       With -x, if there are missing patches, the command exits with  status  1,  otherwise  with
       status 0.

       With -q, produce no output.

       WARNING:  At this time, some error conditions *also* exit with error status 1, however, in
       situations where the caller is not concerned with errors, the exit status is still useful.

   tla join-branch
       add a version as an ancestor of a project tree

       Usage: tla join-branch [options] version

         -h, --help       Display a help message and exit.
         -H               Display a verbose help message and exit.
         -V, --version    Display a release identifier string
                          and exit.
         -A, --archive    Override `my-default-archive´
         -d, --dir DIR    Operate on project tree in DIR (default `.´)
         --dest DEST      Instead of modifying the project tree in-place,
                          make a copy of it to DEST and apply the result to that
         --unescaped      show filenames in unescaped form

       VERSION--base-0 must be a continuation (e.g. tag). The command replays the  changeset  for
       VERSION--base-0 in the project tree, which has the effect of adding the log for the branch
       (making the tag an ancestor of the resulting tree).

   tla sync-tree
       unify a project tree´s patch-log with a given revision

       Usage: tla sync-tree [options] revision

         -h, --help       Display a help message and exit.
         -H               Display a verbose help message and exit.
         -V, --version    Display a release identifier string
                          and exit.
         -A, --archive    Override `my-default-archive´
         -d, --dir DIR    Operate on project tree in DIR (default `.´)
         --dest DEST      Instead of modifying the project tree in-place,
                          make a copy of it to DEST and apply the result to that
         --unescaped      show filenames in unescaped form

       The new project tree is formed by getting the REVISION and adding  all  patch-log  entries
       from REVISION.  No actual merging is performed -- only the patch-log is changed.

   tla delta
       compute a changeset (or diff) between any two trees or revisions

       Usage: tla delta [options] (REVISION|TREE)-A (REVISION|TREE)-B [DESTDIR]

         -h, --help          Display a help message and exit.
         -H                  Display a verbose help message and exit.
         -V, --version       Display a release identifier string
                             and exit.
         -A, --archive       Override `my-default-archive´
         --cache DIR         specify a cache root for pristine copies
         -n, --no-changeset  do not generate a changeset
         --diffs             print changeset report with diffs (implies -n)
         --unescaped         show filenames in unescaped form

       Given  (REVISION|TREE)-A  and (REVISION|TREE)-B, tla will build a changeset that comprises
       the changes between REVISION-A and REVISION-B

       Example:
         tla delta tla--devo--1.1--patch-6             tla--devo--1.1--patch-8 ,,changes

         Will pull patch-6 and patch-8 from tla--devo--1.1 and compute
         a changeset, which will be saved in a newly created ,,changes
         directory. If you would like a report instead,
         append the --diffs option

LOCAL CACHE COMMANDS

       on stdout.  Otherwise, the exit status is the only output.

       By  default,  validation  is strict.  For example, -b checks for a valid basename and does
       not permit a branch label or version number.

       With -t, more specific names are permitted.  For example, -b will permit  a  branch  name,
       version number, and patch level.

ENVIRONMENT

       EDITOR If $EDITOR is set, use its value as the path of the text editor arch is to run when
              asking the user for text input. If unset, log messages must be given on the command
              line using the `-L´ parameter or in the file created by `tla make-log´.

       HOME   User´s home directory, where arch looks for .arch-cache/ and .arch-params/ .

       http_proxy HTTP_PROXY
              If  $http_proxy  or $HTTP_PROXY is set, arch used its value as the URL of the proxy
              to use for WebDAV accesses.  $http_proxy has higher priority than $HTTP_PROXY.   If
              unset, no proxy is used.

       TMPDIR If  $TMPDIR is set, arch creates temporary files in the given directory. Otherwise,
              it uses `/tmp´.

FILES

       ${HOME}/.arch-cache/
              Directory where arch caches archive data

       ${HOME}/.arch-params/
              Directory where all the user´s settings are stored.

       ${HOME}/.arch-params/hook
              Hook script called after every execution of tla.

       ${HOME}/.arch-params/signing/
              Directory where the commands for signing and checking signatures are stored.
