B<mr> [options] action [params ...]
=head1 DESCRIPTION
List the repositories that mr will act on.
+=item register
+
+The next parameter is the directory of an existing repository. The
+repository will be registered in the mrconfig file.
+
+=item config
+
+Modifies the mrconfig file. The next parameter is the name of the section
+to add or modify, and it is followed by one or more instances of
+"parameter=value". Use "parameter=" to remove 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"
+
=item help
Displays this help.
"mr st" is equivilant to "mr status", and "mr up" is equivilant to "mr
update"
-Additional parameters can be passed to other commands than "commit", they
-will be passed on unchanged to the underlying revision control system.
-This is mostly useful if the repositories mr will act on all use the same
-revision control system.
+Additional parameters can be passed to most commands, and are passed on
+unchanged to the underlying revision control system. This is mostly useful
+if the repositories mr will act on all use the same revision control
+system.
=head1 OPTIONS
will try to load a .mrconfig file from the root of the repository. (You
should avoid chaining from repositories with untrusted committers.)
+=item deleted
+
+If the "deleted" parameter is set and its command returns nonzero, then
+B<mr> will treat the repository as deleted. It won't ever actually delete
+the repository, but it will warn if it sees the repsoitory's directory.
+This is useful when one mrconfig file is shared amoung multiple machines,
+to keep track of and remember to delete old repositories.
+
=item lib
The "lib" parameter can specify some shell code that will be run before each
