Here is an example .mrconfig file:
[src]
- checkout = svn co svn://svn.example.com/src/trunk src
+ checkout = svn checkout svn://svn.example.com/src/trunk src
chain = true
[src/linux-2.6]
Within a section, each parameter defines a shell command to run to handle a
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".
+"commit", and other standard actions.
+
+Normally you only need to specify what to do for "checkout". Here you
+specify the command to run in order to create a checkout of the repository.
+The command will be run in the parent directory, and must create the
+repository's directory. So use "git clone", "svn checkout", "bzr branch"
+or "bzr checkout" (for a bound branch), etc.
Note that these shell commands are run in a "set -e" shell
environment, where any additional parameters you pass are available in
-"$@". The "checkout" command is run in the parent of the repository
-directory, since the repository isn't checked out yet. All other commands
-are run inside the repository, though not necessarily at the top of it.
+"$@". All commands other than "checkout" 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. (For the "register" action, "MR_REPO" is instead set to the
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.
+The "MR_ACTION" environment variable is set to the command being run
+(update, checkout, etc).

A few parameters have special meanings:

will skip acting on that repository. The command is passed the action
name in $1.
-Here are two examples. The first skips the repo unless
+Here are three 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.
+been at least 12 hours since the last update. The third skips operating
+on the repo unless it already exists (use mr checkout to enable the repo).
skip = test `whoami` != joey
skip = [ "$1" = update ] && ! hours_since "$1" 12
+ skip = lazy
=item order
Unlike all other parameters, this parameter does not need to be placed
within a section.
+=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
