=head1 DESCRIPTION
B<mr> is a Multiple Repository management tool. It can checkout, update, or
perform other actions on a set of repositories as if they were one combined
-respository. It supports any combination of subversion, git, cvs, mecurial,
+repository. It supports any combination of subversion, git, cvs, mecurial,
bzr and darcs repositories, and support for other revision control systems can
easily be added.
=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.
=over 4
+=item bootstrap url
+
+Causes mr to download the url, save it to a .mrconfig file in the
+current directory, and then check out all repositories listed in it.
+
+(Please only do this if you have reason to trust the url, since
+mrconfig files can contain arbitrary commands!)
+
=item list (or ls)
List the repositories that mr will act on.
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.

-Actions can be abbreviated to any unambiguous subsctring, so
-"mr st" is equivilant to "mr status", and "mr up" is equivilant to "mr
+Actions can be abbreviated to any unambiguous substring, so
+"mr st" is equivalent to "mr status", and "mr up" is equivalent to "mr
update"
Additional parameters can be passed to most commands, and are passed on
Use the specified mrconfig file. The default is B<~/.mrconfig>
+=item -p
+
+Search in the current directory, and its parent directories and use
+the first B<.mrconfig> found, instead of the default B<~/.mrconfig>.
+
=item -v
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
subdirectories deep. For example, with -n 2 it would recurse into ./src/foo,
but not ./src/packages/bar.
-=item -j number
+=item -j [number]
+
+Run the specified number of jobs in parallel, or an unlimited number of jobs
+with no number specified. This can greatly speed up operations such as updates.
+It is not recommended for interactive operations.
-Run the specified number of jobs in parallel. This can greatly speed up
-operations such as updates. It is not recommended for interactive
-operations.
+Note that running more than 10 jobs at a time is likely to run afoul of
+ssh connection limits. Running between 3 and 5 jobs at a time will yield
+a good speedup in updates without loading the machine too much.
=back
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",
override these rcs specific actions. To add a new revision control system,
you can just add rcs specific actions for it.
+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.
+
+=head1 EXTENSIONS
+
+mr can be extended to support things such as unison and git-svn. Some
+files providing such extensions are available in /usr/share/mr/. See
+the documentation in the files for details about using them.
