=head1 NAME
mr - a Multiple Repository management tool
=head1 SYNOPSIS
-/
+
B<mr> [options] checkout
B<mr> [options] update
B<mr> [options] log
+B<mr> [options] bootstrap url
+
B<mr> [options] register [repository]
B<mr> [options] config section ["parameter=[value]" ...]
=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.
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.
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 yeild
+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.

=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.
override these rcs specific actions. To add a new revision control system,
you can just add rcs specific actions for it.

+=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.
