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
-respository. It supports any combination of subversion, git, cvs, mecurial and
-bzr repositories, and support for other revision control systems can easily be
-added.
+respository. It supports any combination of subversion, git, cvs, mecurial,
+bzr and darcs repositories, and support for other revision control systems can
+easily be added.
B<mr> cds into and operates on all registered repositories at or below your
working directory. Or, if you are in a subdirectory of a repository that
Just operate on the repository for the current directory, do not
recurse into deeper repositories.

+Run the specified number of jobs in parallel. This can greatly speed up

+=item order
+
+The "order" parameter can be used to override the default ordering of
+repositories. The default order value is 10. Use smaller values to make
+repositories be processed earlier, and larger values to make repositories
+be processed later.
+
+Note that if a repository is located in a subdirectory of another
+repository, ordering it to be processed earlier is not recommended.
