The mr(1) command can checkout, update, or perform other actions on a set of repositories as if they were one combined respository. It supports any combination of subversion, git, cvs, mercurial, bzr, darcs, cvs, vcsh, fossil and veracity repositories, and support for other revision control systems can easily be added. (There are extensions adding support for unison and git-svn.) It is extremely configurable via simple shell scripting. Some examples of things it can do include: * Update a repository no more frequently than once every twelve hours. * Run an arbitrary command before committing to a repository. * When updating a git repository, pull from two different upstreams and merge the two together. * Run several repository updates in parallel, greatly speeding up the update process. * Remember actions that failed due to a laptop being offline, so they can be retried when it comes back online. ## Get mr mr is available in git at `git://git.kitenet.net/mr`, or [in gitweb](http://git.kitenet.net/?p=mr.git). It's in all recent versions of Debian. If you want a tarball, the best place to get one is from . Unofficial RPMs are provided by [Douglas E. Warner](http://www.silfreed.net/download/repo/packages/mr/). It's also in Mac Homebrew. ## Discuss mr The [VCS-Home](http://vcs-home.madduck.net/) group has a mailing list that is probably the best place to discuss mr. Bugs should be filed to the [Debian BTS](http://bugs.debian.org/mr). ## News [[!inline pages="news/* and !*/Discussion" show="3"]] [[!sidebar content=""" Flattr this """]]
