  19DESCRIPTION
  20-----------
  21Imports a CVS repository into git. It will either create a new
  22repository, or incrementally import into an existing one.
  23
  24Splitting the CVS log into patch sets is done by 'cvsps'.
  25At least version 2.1 is required.
  26
  27You should *never* do any work of your own on the branches that are
  28created by 'git-cvsimport'.  By default initial import will create and populate a
  29"master" branch from the CVS repository's main branch which you're free
  30to work with; after that, you need to 'git-merge' incremental imports, or
  31any CVS branches, yourself.  It is advisable to specify a named remote via
  32-r to separate and protect the incoming branches.
  33
  34If you intend to set up a shared public repository that all developers can
  35read/write, or if you want to use linkgit:git-cvsserver[1], then you
  36probably want to make a bare clone of the imported repository,
  37and use the clone as the shared repository.
  38See linkgit:gitcvs-migration[7].

  41OPTIONS
  42-------
  43-v::
  44        Verbosity: let 'cvsimport' report what it is doing.
  45
  46-d <CVSROOT>::
  47        The root of the CVS archive. May be local (a simple path) or remote;
  48        currently, only the :local:, :ext: and :pserver: access methods
  49        are supported. If not given, 'git-cvsimport' will try to read it
  50        from `CVS/Root`. If no such file exists, it checks for the
  51        `CVSROOT` environment variable.
  52
  53<CVS_module>::
  54        The CVS module you want to import. Relative to <CVSROOT>.
  55        If not given, 'git-cvsimport' tries to read it from
  56        `CVS/Repository`.
  57
  58-C <target-dir>::
  59        The git repository to import to.  If the directory doesn't
  60        exist, it will be created.  Default is the current directory.
  61
  62-r <remote>::
  63        The git remote to import this CVS repository into.
  64        Moves all CVS branches into remotes/<remote>/<branch>
  65        akin to the 'git-clone' "--use-separate-remote" option.
  66
  67-o <branch-for-HEAD>::
  68        When no remote is specified (via -r) the 'HEAD' branch
  69        from CVS is imported to the 'origin' branch within the git
  70        repository, as 'HEAD' already has a special meaning for git.
  71        When a remote is specified the 'HEAD' branch is named
  72        remotes/<remote>/master mirroring 'git-clone' behaviour.
  73        Use this option if you want to import into a different
  74        branch.
  75+
  76Use '-o master' for continuing an import that was initially done by
  77the old cvs2git tool.
  78
  79-i::
  80        Import-only: don't perform a checkout after importing.  This option
  81        ensures the working directory and index remain untouched and will
  82        not create them if they do not exist.
  83
  84-k::
  85        Kill keywords: will extract files with '-kk' from the CVS archive
  86        to avoid noisy changesets. Highly recommended, but off by default
  87        to preserve compatibility with early imported trees.
  88
  89-u::
  90        Convert underscores in tag and branch names to dots.
  91
  92-s <subst>::
  93        Substitute the character "/" in branch names with <subst>
  94
  95-p <options-for-cvsps>::
  96        Additional options for cvsps.
  97        The options '-u' and '-A' are implicit and should not be used here.
  98+
  99If you need to pass multiple options, separate them with a comma.
 100
 101-z <fuzz>::
 102        Pass the timestamp fuzz factor to cvsps, in seconds. If unset,
 103        cvsps defaults to 300s.
 104
 105-P <cvsps-output-file>::
 106        Instead of calling cvsps, read the provided cvsps output file. Useful
 107        for debugging or when cvsps is being handled outside cvsimport.
 108
 109-m::
 110        Attempt to detect merges based on the commit message. This option
 111        will enable default regexes that try to capture the source
 112        branch name from the commit message.
 113
 114-M <regex>::
 115        Attempt to detect merges based on the commit message with a custom
 116        regex. It can be used with '-m' to enable the default regexes
 117        as well. You must escape forward slashes.
 118+
 119The regex must capture the source branch name in $1.
 120+
 121This option can be used several times to provide several detection regexes.
 122
 123-S <regex>::
 124        Skip paths matching the regex.
 125
 126-a::
 127        Import all commits, including recent ones. cvsimport by default
 128        skips commits that have a timestamp less than 10 minutes ago.
 129
 130-L <limit>::
 131        Limit the number of commits imported. Workaround for cases where
 132        cvsimport leaks memory.
 133
 134-A <author-conv-file>::
 135        CVS by default uses the Unix username when writing its
 136        commit logs. Using this option and an author-conv-file
 137        in this format
 138+
 139---------
 140        exon=Andreas Ericsson <ae@op5.se>
 141        spawn=Simon Pawn <spawn@frog-pond.org>
 142
 143---------
 144+
 145'git-cvsimport' will make it appear as those authors had
 146their GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL set properly
 147all along.
 148+
 149For convenience, this data is saved to `$GIT_DIR/cvs-authors`
 150each time the '-A' option is provided and read from that same
 151file each time 'git-cvsimport' is run.
 152+
 153It is not recommended to use this feature if you intend to
 154export changes back to CVS again later with
 155'git-cvsexportcommit'.
 156
 157-h::
 158        Print a short usage message and exit.
 159
 160OUTPUT
 161------
 162If '-v' is specified, the script reports what it is doing.
 163
 164Otherwise, success is indicated the Unix way, i.e. by simply exiting with
 165a zero exit status.
