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. + +You should *never* do any work of your own on the branches that are +created by git-cvsimport. The 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. + +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. + +-o <branch-for-HEAD>:: + The 'HEAD' branch from CVS is imported to the 'origin' branch within + the git repository, as 'HEAD' already has a special meaning for git. + 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 name 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 also see the default regexes. + You must escape forward slashes. + +-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 + in this format ++ +--------- + exon=Andreas Ericsson <ae@op5.se> + spawn=Simon Pawn <spawn@frog-pond.org> + +--------- ++ +git-cvsimport will make it appear as those authors had +their GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL set properly +all along. ++ +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 +gitlink:git-cvsexportcommit[1]. + +-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. + + +Author +------ +Written by Matthias Urlichs <smurf@smurf.noris.de>, with help from +various participants of the git-list <git@vger.kernel.org>. + +Documentation +-------------- +Documentation by Matthias Urlichs <smurf@smurf.noris.de>. + +GIT +--- +Part of the gitlink:git[7] suite + |
