=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
The .mrconfig file uses a variant of the INI file format. Lines starting with
"#" are comments. Lines ending with "\" are continued on to the next line.
-The "default" section allows setting default values for the sections that
+The "DEFAULT" section allows setting default values for the sections that
come after it.
-The "alias" section allows adding aliases for actions. Each parameter
+The "ALIAS" section allows adding aliases for actions. Each parameter
is an alias, and its value is the action to use.
-All other sections specify where each repository is located, relative to the
-directory that contains the .mrconfig file.
+All other sections add repositories. The section header specifies the
+directory where the repository is located. This is relative to the directory
+that contains the mrconfig file, but you can also choose to use absolute
+paths.
Within a section, each parameter defines a shell command to run to handle a
given action. mr contains default handlers for the "update", "status", and
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
