Description: 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, and fossil repositories, and support for other revision control systems can easily be added. (There are extensions adding support for unison and git-svn.)
