-=item checkout
+=item checkout (or co)
Checks out all the registered repositories that are not already checked
out.
Displays a status report for each registered repository, showing what
uncommitted changes are present in the repository.
-=item commit
+=item commit (or ci)
Commits changes to each registered repository. (By default, changes
are pushed to the remote repository too, when using distributed systems

+B<mr> is configured by .mrconfig files. It starts by reading the .mrconfig
+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.

+There are three 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
+"lib" parameter can specify some shell code that will be run before each
+command, this can be a useful way to define shell functions other commands
+can use.
The "default" section allows setting up default handlers for each action,
and is overridden by the contents of other sections. mr contains default
handlers for the "update", "status", and "commit" actions, so normally
you only need to specify what to do for "checkout".
+The "alias" section allows adding aliases for commands. Each parameter
+is an alias, and its value is the command to run.

For example:
[src]
checkout = svn co svn://svn.example.com/src/trunk src
+ chain = true
[src/linux-2.6]
- # only check this out on kodama
- skip = test $(hostname) != kodama
+ skip = small
checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
