NAME
       git-cvsimport - Salvage your data out of	another	SCM people love	to
       hate

SYNOPSIS
       git cvsimport [-o <branch-for-HEAD>] [-h] [-v] [-d <CVSROOT>]
		     [-A <author-conv-file>] [-p <options-for-cvsps>] [-P <file>]
		     [-C <git_repository>] [-z <fuzz>] [-i] [-k] [-u] [-s <subst>]
		     [-a] [-m] [-M <regex>] [-S	<regex>] [-L <commitlimit>]
		     [-r <remote>] [-R]	[<CVS_module>]

DESCRIPTION
       WARNING:	git cvsimport uses cvsps version 2, which is considered
       deprecated; it does not work with cvsps version 3 and later. If you are
       performing a one-shot import of a CVS repository	consider using
       cvs2git[1] or cvs-fast-export[2].

       Imports a CVS repository	into Git. It will either create	a new
       repository, or incrementally import into	an existing one.

       Splitting the CVS log into patch	sets is	done by	cvsps. At least
       version 2.1 is required.

       WARNING:	for certain situations the import leads	to incorrect results.
       Please see the section ISSUES for further reference.

       You should never	do any work of your own	on the branches	that are
       created by git cvsimport. By default initial import will	create and
       populate	a "master" branch from the CVS repository's main branch	which
       you're free to work with; after that, you need to git merge incremental
       imports,	or any CVS branches, yourself. It is advisable to specify a
       named remote via	-r to separate and protect the incoming	branches.

       If you intend to	set up a shared	public repository that all developers
       can read/write, or if you want to use git-cvsserver(1), then you
       probably	want to	make a bare clone of the imported repository, and use
       the clone as the	shared repository. See gitcvs-migration(7).

OPTIONS
       -v
	   Verbosity: let cvsimport report what	it is doing.

       -d <CVSROOT>
	   The root of the CVS archive.	May be local (a	simple path) or
	   remote; currently, only the :local:,	:ext: and :pserver: access
	   methods are supported. If not given,	git cvsimport will try to read
	   it from CVS/Root. If	no such	file exists, it	checks for the CVSROOT
	   environment variable.

       <CVS_module>
	   The CVS module you want to import. Relative to <CVSROOT>. If	not
	   given, git cvsimport	tries to read it from CVS/Repository.

       -C <target-dir>
	   The Git repository to import	to. If the directory doesn't exist, it
	   will	be created. Default is the current directory.

       -r <remote>
	   The Git remote to import this CVS repository	into. Moves all	CVS
	   branches into remotes/<remote>/<branch> akin	to the way git clone
	   uses	origin by default.

       -o <branch-for-HEAD>
	   When	no remote is specified (via -r)	the HEAD branch	from CVS is
	   imported to the origin branch within	the Git	repository, as HEAD
	   already has a special meaning for Git. When a remote	is specified
	   the HEAD branch is named remotes/<remote>/master mirroring git
	   clone behaviour. Use	this option if you want	to import into a
	   different branch.

	   Use -o master for continuing	an import that was initially done by
	   the old cvs2git tool.

       -i
	   Import-only:	don't perform a	checkout after importing. This option
	   ensures the working directory and index remain untouched and	will
	   not create them if they do not exist.

       -k
	   Kill	keywords: will extract files with -kk from the CVS archive to
	   avoid noisy changesets. Highly recommended, but off by default to
	   preserve compatibility with early imported trees.

       -u
	   Convert underscores in tag and branch names to dots.

       -s <subst>
	   Substitute the character "/"	in branch names	with <subst>

       -p <options-for-cvsps>
	   Additional options for cvsps. The options -u	and -A are implicit
	   and should not be used here.

	   If you need to pass multiple	options, separate them with a comma.

       -z <fuzz>
	   Pass	the timestamp fuzz factor to cvsps, in seconds.	If unset,
	   cvsps defaults to 300s.

       -P <cvsps-output-file>
	   Instead of calling cvsps, read the provided cvsps output file.
	   Useful for debugging	or when	cvsps is being handled outside
	   cvsimport.

       -m
	   Attempt to detect merges based on the commit	message. This option
	   will	enable default regexes that try	to capture the source branch
	   name	from the commit	message.

       -M <regex>
	   Attempt to detect merges based on the commit	message	with a custom
	   regex. It can be used with -m to enable the default regexes as
	   well. You must escape forward slashes.

	   The regex must capture the source branch name in $1.

	   This	option can be used several times to provide several detection
	   regexes.

       -S <regex>
	   Skip	paths matching the regex.

       -a
	   Import all commits, including recent	ones. cvsimport	by default
	   skips commits that have a timestamp less than 10 minutes ago.

       -L <limit>
	   Limit the number of commits imported. Workaround for	cases where
	   cvsimport leaks memory.

       -A <author-conv-file>
	   CVS by default uses the Unix	username when writing its commit logs.
	   Using this option and an author-conv-file maps the name recorded in
	   CVS to author name, e-mail and optional time	zone:

		       exon=Andreas Ericsson <ae@op5.se>
		       spawn=Simon Pawn	<spawn@frog-pond.org> America/Chicago

	   git cvsimport will make it appear as	those authors had their
	   GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL	set properly all along.	If a
	   time	zone is	specified, GIT_AUTHOR_DATE will	have the corresponding
	   offset applied.

	   For convenience, this data is saved to $GIT_DIR/cvs-authors each
	   time	the -A option is provided and read from	that same file each
	   time	git cvsimport is run.

	   It is not recommended to use	this feature if	you intend to export
	   changes back	to CVS again later with	git cvsexportcommit.

       -R
	   Generate a $GIT_DIR/cvs-revisions file containing a mapping from
	   CVS revision	numbers	to newly-created Git commit IDs. The generated
	   file	will contain one line for each (filename, revision) pair
	   imported; each line will look like

	       src/widget.c 1.1	1d862f173cdc7325b6fa6d2ae1cfd61fd1b512b7

	   The revision	data is	appended to the	file if	it already exists, for
	   use when doing incremental imports.

	   This	option may be useful if	you have CVS revision numbers stored
	   in commit messages, bug-tracking systems, email archives, and the
	   like.

       -h
	   Print a short usage message and exit.

OUTPUT
       If -v is	specified, the script reports what it is doing.

       Otherwise, success is indicated the Unix	way, i.e. by simply exiting
       with a zero exit	status.

ISSUES
       Problems	related	to timestamps:

       o   If timestamps of commits in the CVS repository are not stable
	   enough to be	used for ordering commits changes may show up in the
	   wrong order.

       o   If any files	were ever "cvs import"ed more than once	(e.g., import
	   of more than	one vendor release) the	HEAD contains the wrong
	   content.

       o   If the timestamp order of different files cross the revision	order
	   within the commit matching time window the order of commits may be
	   wrong.

       Problems	related	to branches:

       o   Branches on which no	commits	have been made are not imported.

       o   All files from the branching	point are added	to a branch even if
	   never added in CVS.

       o   This	applies	to files added to the source branch after a daughter
	   branch was created: if previously no	commit was made	on the
	   daughter branch they	will erroneously be added to the daughter
	   branch in git.

       Problems	related	to tags:

       o   Multiple tags on the	same revision are not imported.

       If you suspect that any of these	issues may apply to the	repository you
       want to import, consider	using cvs2git:

       o   cvs2git (part of cvs2svn), http://subversion.apache.org/

GIT
       Part of the git(1) suite
