=head1 DESCRIPTION
B<mr> is a Multiple Repository management tool. It can checkout, update, or
=item commit (or ci)
Commits changes to each repository. (By default, changes are pushed to the
-remote repository too, when using distributed systems like git.)
+remote repository too, when using distributed systems like git. If you
+don't like this default, you can change it in your .mrconfig, or use record
+instead.)
+
+The optional -m parameter allows specifying a commit message.
+
+=item record
+
+Records changes to the local repository, but does not push them to the
+remote repository. Only supported for distributed revision control systems.
The optional -m parameter allows specifying a commit message.
+=item push
+
+Pushes committed local changes to the remote repository. A no-op for
+centralized revision control systems.
+
=item diff
Show a diff of uncommitted changes.
The ~/.mrconfig file is used by default. To use a different config file,
use the -c option.
+=item offline
+
+Advises mr that it is in offline mode. Any commands that fail in
+offline mode will be remembered, and retried when mr is told it's online.
+
+=item online
+
+Advices mr that it is in online mode again. Commands that failed while in
+offline mode will be re-run.
+
+=item remember
+
+Remember a command, to be run later when mr re-enters online mode. This
+implicitly puts mr into offline mode. The command can be any regular mr
+command. This is useful when you know that a command will fail due to being
+offline, and so don't want to run it right now at all, but just remember
+to run it when you go back online.
+
=item help
Displays this help.
Be verbose.
+=item -q
+
+Be quiet.
+
=item -s
Expand the statistics line displayed at the end to include information
about exactly which repositories failed and were skipped, if any.
+=item -i
+
+Interactive mode. If a repository fails to be processed, a subshell will be
+started which you can use to resolve or investigate the problem. Exit the
+subshell to continue the mr run.
+
=item -n [number]
If no number if specified, just operate on the repository for the current
=head1 FILES
+The ~/.mrlog file contains commands that mr has remembered to run later,
+due to being offline. You can delete or edit this file to remove commands,
+or even to add other commands for 'mr online' to run. If the file is
+present, mr assumes it is in offline mode.
+
B<mr> is configured by .mrconfig files. It starts by reading the .mrconfig
file in your home directory, and this can in turn chain load .mrconfig files
from repositories.
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.
+paths. (Note that you can use environment variables in section names; they
+will be passed through the shell for expansion. For example,
+"[$HOSTNAME]", or "[${HOSTNAME}foo]")
Within a section, each parameter defines a shell command to run to handle a
given action. mr contains default handlers for "update", "status",
