=head1 NAME
mr - a Multiple Repository management tool
It is not recommended for interactive operations.
Note that running more than 10 jobs at a time is likely to run afoul of
-ssh connection limits. Running between 3 and 5 jobs at a time will yeild
+ssh connection limits. Running between 3 and 5 jobs at a time will yield
a good speedup in updates without loading the machine too much.
=back
override these rcs specific actions. To add a new revision control system,
you can just add rcs specific actions for it.
+=head1 EXTENSIONS
+
+mr can be extended to support things such as unison and remote git
+checkout. Some files providing such extensions are available in
+/usr/share/mr/. See the documentation in the files for details about using
+them.
