B<mr> [options] action [params ...]
=head1 DESCRIPTION
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".
+B<mr> cds into and 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 stay in that directory,
+and work on only that repository,
+
The predefined commands should be fairly familiar to users of any revision
control system:
Show a diff of uncommitted changes.
-=item list
+=item log
+
+Show the commit log.
+
+=item list (or ls)
List the repositories that mr will act on.
=back
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, it will act on
-only that repository.
+"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.
=item -c mrconfig

+Use the specified mrconfig file, instead of looking for one in your home
directory.
=item -v
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.
-Sections specify where each repository is located, relative to the
+
+The "default" section allows setting default values for the sections that
+come after it.
+
+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.
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
+given action. mr contains default handlers for the "update", "status", and
+"commit" actions, so normally you only need to specify what to do for
+"checkout".
+
+Note that these shell commands are run in a "set -e" shell
environment, where any additional parameters you pass are available in
"$@". The "checkout" command is run in the parent of the repository
directory, since the repository isn't checked out yet. All other commands
will try to load a .mrconfig file from the root of the repository. (You
should avoid chaining from repositories with untrusted committers.) The
"lib" parameter can specify some shell code that will be run before each
-command, this can be a useful way to define shell functions other commands
-can use.
-
-The "default" section allows setting up default handlers for each action,
-and is overridden by the contents of other sections. mr contains default
-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.
