mr - a Multiple Repository management tool
=head1 DESCRIPTION
-B<mr> is a Multiple Repository management tool. It allows you to register a
-set of repositories in a .mrconfig file, and then checkout, update, or
-perform other actions on the repositories as if they were one big
-respository.
-
-Any mix of revision control systems can be used with B<mr>, and you can
-define arbitrary actions for commands like "update", "checkout", or "commit".
+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, and bzr repositories,
+and support for other revision control systems can easily be added.
B<mr> cds into and operates on all registered repsitories at or below your
working directory. Or, if you are in a subdirectory of a repository that
contains no other registered repositories, it will stay in that directory,
and work on only that repository,
-The predefined commands should be fairly familiar to users of any revision

=item list (or ls)
List the repositories that mr will act on.

-Adds, modifies, removed, or prints a value from the mrconfig file. The next
-parameter is the name of the section the value is in. To add or modify a
-value, follow it by one or more instances of "parameter=value". Use
-"parameter=" to remove a parameter. Use just "parameter" to get the value
-of a parameter.

For example, to add (or edit) a repository in src/foo:
mr config src/foo checkout="svn co svn://example.com/foo/trunk foo"
+To show the command that mr uses to update the repository in src/foo:
+
+ mr config src/foo update

Displays this help.
Be verbose.
