B<mr> [options] action [params ...]
=head1 DESCRIPTION
List the repositories that mr will act on.
+=item register
+
+The next parameter is the directory of an existing repository. The
+repository will be registered in the mrconfig file.
+
+=item config
+
+Modifies the mrconfig file. The next parameter is the name of the section
+to add or modify, and it is followed by one or more instances of
+"parameter=value". Use "parameter=" to remove a parameter.
+
+For example, to register a new svn repository in src/foo:
+
+ mr config src/foo checkout="svn co svn://example.com/foo/trunk"
+
=item help
Displays this help.
=head1 FILES
B<mr> is configured by .mrconfig files. It starts by reading the .mrconfig
-file in your home directory. Each repository specified in a .mrconfig file
-can also have its own .mrconfig file in its root directory that can
-optionally be used as well. So you could have a ~/.mrconfig that registers a
-repository ~/src, that itself contains a ~/src/.mrconfig file, that in turn
-registers several additional repositories.
+file in your home directory, and this can in turn chain load .mrconfig files
+from repositories.
+
+Here is an example .mrconfig file:
+
+ [src]
+ checkout = svn co svn://svn.example.com/src/trunk src
+ chain = true
+
+ [src/linux-2.6]
+ checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
The .mrconfig file uses a variant of the INI file format. Lines starting with
"#" are comments. Lines ending with "\" are continued on to the next line.
-Sections specify where each repository is located, relative to the
-directory that contains the .mrconfig file.
+
+The "DEFAULT" section allows setting default values for the sections that
+come after it.
+
+The "ALIAS" section allows adding aliases for actions. Each parameter
+is an alias, and its value is the action to use.
+
+All other sections add repositories. The section header specifies the
+directory where the repository is located. This is relative to the directory
+that contains the mrconfig file, but you can also choose to use absolute
+paths.
Within a section, each parameter defines a shell command to run to handle a
-given action. Note that these shell commands are run in a "set -e" shell
+given action. mr contains default handlers for the "update", "status", and
+"commit" actions, so 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
The "MR_REPO" environment variable is set to the path to the top of the
repository.
-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.
+A few parameters have special meanings:
+
+=over 4
+
+=item skip
+
+If the "skip" parameter is set and its command returns nonzero, then B<mr>
+will skip acting on that repository.
+
+=item chain
+
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
-should avoid chaining from repositories with untrusted committers.) The
-"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.
-
-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".
+should avoid chaining from repositories with untrusted committers.)
-The "alias" section allows adding aliases for commands. Each parameter
-is an alias, and its value is the command to run.
+=item deleted
-For example:
+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.
