Any mix of revision control systems can be used with B<mr>, and you can

+The predefined commands should be fairly familiar to users of any revision

+
+=item checkout
+
+Checks out all the registered repositories that are not already checked
+out.
+
+=item update
+
+Updates each registered repository from its configured remote repository.
+
+If a repository isn't checked out yet, it will first check it out.
+
+=item status
+
+Displays a status report for each registered repository, showing what
+uncommitted changes are present in the repository.
+
+=item commit
+
+Commits changes to each registered repository. (By default, changes
+are pushed to the remote repository too, when using distributed systems
+like git.)
+
+The optional -m parameter allows specifying a commit message.

+Actions can be abbreviated to any unambiguous subsctring, so
+"mr st" is equivilant to "mr status".

+file in your home directory. Each repository specified in a .mrconfig file
+can also have its own .mrconfig file in its root directory that can
+optionally be used as well. So you could have a ~/.mrconfig that registers a
repository ~/src, that itself contains a ~/src/.mrconfig file, that in turn
registers several additional repositories.
Within a section, each parameter defines a shell command to run to handle a
given action. Note that these shell commands are run in a "set -e" shell
-environment, and B<mr> cds into the repository directory before running
-them, except for the "checkout" command, which is run in the parent of the

+"$@". B<mr> cds into the repository directory before running
+a command, except for the "checkout" command, which is run in the parent
+of the repository directory, since the repository isn't checked out yet.
There are two special parameters. If the "skip" parameter is set and
its command returns nonzero, then B<mr> will skip acting on that repository.
+If the "chain" parameter is set and its command returns nonzero, then B<mr>
+will try to load a .mrconfig file from the root of the repository. (You
+should avoid chaining from repositories with untrusted committers.)
The "default" section allows setting up default handlers for each action,
and is overridden by the contents of other sections. mr contains default
