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 suppplied. If it cannot find the remote branch a merge comes from
+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

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.

+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

OPTIONS
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.
+
+-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.
