NAME

   git-archimport - Import an Arch repository into Git

SYNOPSIS

   git archimport [-h] [-v] [-o] [-a] [-f] [-T] [-D depth] [-t tempdir]
                  <archive/branch>[:<git-branch>] ...

DESCRIPTION

   Imports a project from one or more Arch repositories. It will follow
   branches and repositories within the namespaces defined by the
   <archive/branch> parameters supplied. If it cannot find the remote
   branch a merge comes from it will just import it as a regular commit.
   If it can find it, it will mark it as a merge whenever possible (see
   discussion below).

   The script expects you to provide the key roots where it can start the
   import from an initial import or tag type of Arch commit. It will
   follow and import new branches within the provided roots.

   It expects to be dealing with one project only. If it sees branches
   that have different roots, it will refuse to run. In that case, edit
   your <archive/branch> parameters to define clearly the scope of the
   import.

   git archimport uses tla extensively in the background to access the
   Arch repository. Make sure you have a recent version of tla available
   in the path. tla must know about the repositories you pass to git
   archimport.

   For the initial import, git archimport expects to find itself in an
   empty directory. To follow the development of a project that uses Arch,
   rerun git archimport with the same parameters as the initial import to
   perform incremental imports.

   While git archimport will try to create sensible branch names for the
   archives that it imports, it is also possible to specify Git branch
   names manually. To do so, write a Git branch name after each
   <archive/branch> parameter, separated by a colon. This way, you can
   shorten the Arch branch names and convert Arch jargon to Git jargon,
   for example mapping a "PROJECT--devo--VERSION" branch to "master".

   Associating multiple Arch branches to one Git branch is possible; the
   result will make the most sense only if no commits are made to the
   first branch, after the second branch is created. Still, this is useful
   to convert Arch repositories that had been rotated periodically.

MERGES

   Patch merge data from Arch is used to mark merges in Git as well. Git
   does not care much about tracking patches, and only considers a merge
   when a branch incorporates all the commits since the point they forked.
   The end result is that Git will have a good idea of how far branches
   have diverged. So the import process does lose some patch-trading
   metadata.

   Fortunately, when you try and merge branches imported from Arch, Git
   will find a good merge base, and it has a good chance of identifying
   patches that have been traded out-of-sequence between the branches.

OPTIONS

   -h
       Display usage.

   -v
       Verbose output.

   -T
       Many tags. Will create a tag for every commit, reflecting the
       commit name in the Arch repository.

   -f
       Use the fast patchset import strategy. This can be significantly
       faster for large trees, but cannot handle directory renames or
       permissions changes. The default strategy is slow and safe.

   -o
       Use this for compatibility with old-style branch names used by
       earlier versions of git archimport. Old-style branch names were
       category--branch, whereas new-style branch names are
       archive,category--branch--version. In both cases, names given on
       the command-line will override the automatically-generated ones.

   -D <depth>
       Follow merge ancestry and attempt to import trees that have been
       merged from. Specify a depth greater than 1 if patch logs have been
       pruned.

   -a
       Attempt to auto-register archives at
       http://mirrors.sourcecontrol.net This is particularly useful with
       the -D option.

   -t <tmpdir>
       Override the default tempdir.

   <archive/branch>
       Archive/branch identifier in a format that tla log understands.
