-B<mr> is a Multiple Repository management tool. It

-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.
+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 and
+bzr repositories, and support for other revision control systems can easily be
+added.
B<mr> cds into and operates on all registered repositories at or below your
working directory. Or, if you are in a subdirectory of a repository that

+Register an existing repository in a mrconfig file. By default, the
repository in the current directory is registered, or you can specify a
directory to register.
-By default it registers it to the ~/.mrconfig file. To make it write to a
-different file, use the -c option.
+The mrconfig file that is modified is chosen by either the -c option, or by
+looking for the closest known one at or below the current directory.
=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.
mr config src/foo update
+To see the built-in library of shell functions contained in mr:
+
+ mr config DEFAULT lib
+
+The ~/.mrconfig file is used by default. To use a different config file,
+use the -c option.
+
=item help
Displays this help.
=item -c mrconfig
-Use the specified mrconfig file, instead of looking for one in your home
-directory.
+Use the specified mrconfig file. The default is B<~/.mrconfig>
=item -v
Just operate on the repository for the current directory, do not
recurse into deeper repositories.
+=item -j number
+
+Run the specified number of jobs in parallel. This can greatly speed up
+operations such as updates. It is not recommended for interactive
+operations.

+given action. mr contains default handlers for "update", "status",
+"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
are run inside the repository, though not necessarily at the top of it.
The "MR_REPO" environment variable is set to the path to the top of the
-repository, and "MR_CONFIG" 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 mr thinks it should be added to.
+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:
been at least 12 hours since the last update.
skip = test $(whoami) != joey
- 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, as this
+can cause confusion during checkouts.
=item chain
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 true, 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 repository'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
