 =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,
