-a set of repositories as if they were one combined respository. It
-supports any combination of subversion, git, cvs, and bzr repositories,
-and support for other revision control systems can easily be added.

+The mrconfig file that is modified is chosen by either the -c option, or by

=item config
-Adds, modifies, removes, or prints a value from the mrconfig file. The next
+Adds, modifies, removes, or prints a value from a mrconfig file. The next
parameter is the name of the section the value is in. To add or modify
values, use one or more instances of "parameter=value". Use "parameter=" to
remove a parameter. Use just "parameter" to get the value of a parameter.

+The ~/.mrconfig file is used by default. To use a different config file,

=item help
Displays this help.
=item -c mrconfig
-Use the specified mrconfig file, instead of looking for one in your home

+Run the specified number of jobs in parallel. This can greatly speed up

+"commit", and other standard actions. 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
are run inside the repository, though not necessarily at the top of it.

+repository. The "MR_CONFIG" environment variable is set to the .mrconfig file
+that defines the repo being acted on, or, if the repo is not yet in a config
+file, the .mrconfig file that should be modified to register the repo.
A few parameters have special meanings:

- skip = [ "$1" = update ] && [ $(hours_since "$1") -lt 12 ]
+ skip = [ "$1" = update ] && ! hours_since "$1" 12
+
+=item order
+
+The "order" parameter can be used to override the default ordering of
+repositories. The default order value is 10. Use smaller values to make
+repositories be processed earlier, and larger values to make repositories
+be processed later.
+
+Note that if a repository is located in a subdirectory of another
+repository, ordering it to be processed earlier is not recommended.
=item chain
-If the "chain" parameter is set and its command returns nonzero, then B<mr>
+If the "chain" parameter is set and its command returns true, then B<mr>
will try to load a .mrconfig file from the root of the repository. (You
should avoid chaining from repositories with untrusted committers.)
-=item deleted
-
-If the "deleted" parameter is set and its command returns nonzero, then
-B<mr> will treat the repository as deleted. It won't ever actually delete
-the repository, but it will warn if it sees the repsoitory's directory.
-This is useful when one mrconfig file is shared amoung multiple machines,
-to keep track of and remember to delete old repositories.

=item lib
The "lib" parameter can specify some shell code that will be run before each
