B<mr> is a Multiple Repository management tool. It can checkout, update, or
perform other actions on a set of repositories as if they were one combined

bzr and darcs repositories, and support for other revision control systems can
easily be added.
=item commit (or ci)
Commits changes to each repository. (By default, changes are pushed to the
-remote repository too, when using distributed systems like git.)

+Records changes to the local repository, but does not push them to the

Within a section, each parameter defines a shell command to run to handle a
given action. mr contains default handlers for "update", "status",
(included in mr's built-in library) to skip updating the repo unless it's
been at least 12 hours since the last update.
