GIT-ARCHIMPORT(1)		  Git Manual		     GIT-ARCHIMPORT(1)

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.
