-B<mr> is a Multiple Repository management tool. It allows you to register a
-set of repositories in a .mrconfig file, and then checkout, update, or
-perform other actions on the repositories as if they were one big
-respository.
+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,
+bzr and darcs repositories, and support for other revision control systems can
+easily be added.

 
 

-Any mix of revision control systems can be used with B<mr>, and you can
-define arbitrary actions for commands like "update", "checkout", or "commit".
+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
+contains no other registered repositories, it will stay in that directory,
+and work on only that repository,

+from repositories.

+Here is an example .mrconfig file:

+  chain = true
+
+  [src/linux-2.6]

+is an alias, and its value is the action to use.

+All other sections add repositories. The section header specifies the

+
+Note that these shell commands are run in a "set -e" shell

 directory, since the repository isn't checked out yet. All other commands

+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.

 
 

-There are three special parameters. If the "skip" parameter is set and
-its command returns nonzero, then B<mr> will skip acting on that repository.
-If the "chain" parameter is set and its command returns nonzero, then B<mr>
-will try to load a .mrconfig file from the root of the repository. (You

-"lib" parameter can specify some shell code that will be run before each
-command, this can be a useful way to define shell functions other commands
-can use.
+A few parameters have special meanings:

 
 

-The "default" section allows setting up default handlers for each action,
-and is overridden by the contents of other sections. mr contains default
-handlers for the "update", "status", and "commit" actions, so normally
-you only need to specify what to do for "checkout".

-The "alias" section allows adding aliases for commands. Each parameter
-is an alias, and its value is the command to run.
+=item skip

 
 

-For example:
+If the "skip" parameter is set and its command returns true, then B<mr>
+will skip acting on that repository. The command is passed the action
+name in $1.

 
 

-  [src]
-  checkout = svn co svn://svn.example.com/src/trunk src
-  chain = true
+Here are two examples. The first skips the repo unless
+mr is run by joey. The second uses the hours_since function
+(included in mr's built-in library) to skip updating the repo unless it's
+been at least 12 hours since the last update.

 
 

-  [src/linux-2.6]
-  skip = small
-  checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

-  [default]
-  lib = \
-  small() {
-       case "$(hostname)" in; \

-               return 0; ;; ; \

-       return 1; \
-  }
+  skip = test $(whoami) != joey
+  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 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.)
