=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 all of the repositories at once.
+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".

If a repository isn't checked out yet, it will first check it out.

Actions can be abbreviated to any unambiguous subsctring, so
"mr st" is equivilant to "mr status".
+B<mr> 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 act on only that repository.
+
+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.

=item -d directory
Specifies the topmost directory that B<mr> should work in. The default is
-the current working directory. B<mr> will operate on all registered
-repositories at or under the directory.

=item -c mrconfig
Within a section, each parameter defines a shell command to run to handle a
given action. Note that these shell commands are run in a "set -e" shell
environment, where any additional parameters you pass are available in
-"$@". B<mr> cds into the repository directory before running
-a command, except for the "checkout" command, which is run in the parent
-of the repository directory, since the repository isn't checked out yet.
+"$@". The "checkout" command is run in the parent of the repository
+directory, since the repository isn't checked out yet. All other commands
+are run inside the repository, though not necessarily at the top of it.
+The "MR_REPO" environment variable is set to the path to the top of the
+repository.
There are three special parameters. If the "skip" parameter is set and
its command returns nonzero, then B<mr> will skip acting on that repository.
handlers for the "update", "status", and "commit" actions, so normally
you only need to specify what to do for "checkout".
+The "alias" section allows adding aliases for commands. Each parameter
+is an alias, and its value is the command to run.
