=head1 DESCRIPTION
List the repositories that mr will act on.
+=item register
+
+Register an existing repository in the mrconfig file. By default, the
+epository in the current directory is registered, or you can specify a
+directory to register.
+
+=item config
+
+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"
+
=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
=item skip
If the "skip" parameter is set and its command returns nonzero, then B<mr>
-will skip acting on that repository.
+will skip acting on that repository. The command is passed the action
+name in $1.
+
+Here are two examples. The first skips the repo unless
+mr is run by joey. The second uses the hours_since function
+(included in mr's built-in library) to skip updating the repo unless it's
+been at least 12 hours since the last update.
+
+ skip = test $(whoami) != joey
+ skip = [ "$1" = update ] && [ $(hours_since "$1") -lt 12 ]
