31 git-archimport \- Import a GNU Arch repository into Git
35 \fIgit archimport\fR [\-h] [\-v] [\-o] [\-a] [\-f] [\-T] [\-D <depth>] [\-t <tempdir>]
36 <archive>/<branch>[:<git\-branch>]\&...\:
40 Imports a project from one or more GNU 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)\&.
42 The script expects you to provide the key roots where it can start the import from an \fIinitial import\fR or \fItag\fR type of Arch commit\&. It will follow and import new branches within the provided roots\&.
44 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\&.
46 \fIgit archimport\fR uses \fBtla\fR extensively in the background to access the Arch repository\&. Make sure you have a recent version of \fBtla\fR available in the path\&. \fBtla\fR must know about the repositories you pass to \fIgit archimport\fR\&.
48 For the initial import, \fIgit archimport\fR expects to find itself in an empty directory\&. To follow the development of a project that uses Arch, rerun \fIgit archimport\fR with the same parameters as the initial import to perform incremental imports\&.
50 While \fIgit archimport\fR 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"\&.
52 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\&.
55 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\&.
57 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\&.
72 Many tags\&. Will create a tag for every commit, reflecting the commit name in the Arch repository\&.
77 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\&.
82 Use this for compatibility with old\-style branch names used by earlier versions of
83 \fIgit archimport\fR\&. 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\&.
88 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\&.
93 Attempt to auto\-register archives at
94 \fBhttp://mirrors\&.sourcecontrol\&.net\fR
95 This is particularly useful with the \-D option\&.
100 Override the default tempdir\&.
