=head1 DESCRIPTION
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 all of the repositories at once.
+perform other actions on the repositories as if they were one big
+respository.
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 repsitories 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,
+
The predefined commands should be fairly familiar to users of any revision
control system:
=over 4
-=item checkout
+=item checkout (or co)
-Checks out all the registered repositories that are not already checked
-out.
+Checks out any repositories that are not already checked out.
=item update
-Updates each registered repository from its configured remote repository.
+Updates each repository from its configured remote repository.
If a repository isn't checked out yet, it will first check it out.
=item status
-Displays a status report for each registered repository, showing what
+Displays a status report for each repository, showing what
uncommitted changes are present in the repository.
-=item commit
+=item commit (or ci)
-Commits changes to each registered repository. (By default, changes
-are pushed to the remote repository too, when using distributed systems
-like git.)
+Commits changes to each repository. (By default, changes are pushed to the
+remote repository too, when using distributed systems like git.)
The optional -m parameter allows specifying a commit message.
+=item diff
+
+Show a diff of uncommitted changes.
+
+=item log
+
+Show the commit log.
+
+=item list (or ls)
+
+List the repositories that mr will act on.
+
+=item register
+
+Register an existing repository in the mrconfig file. By default, the
+epository in the current directory is registered, or you can specify a
+directory to register.
+
+=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 add (or edit) a repository in src/foo:
+
+ mr config src/foo checkout="svn co svn://example.com/foo/trunk foo"
+
+=item help
+
+Displays this help.
+

Actions can be abbreviated to any unambiguous subsctring, so
-"mr st" is equivilant to "mr status".
+"mr st" is equivilant to "mr status", and "mr up" is equivilant to "mr
+update"
+
+Additional parameters can be passed to most commands, and are passed on
+unchanged to the underlying revision control system. This is mostly useful
+if the repositories mr will act on all use the same revision control
+system.
=head1 OPTIONS
=item -d directory
Specifies the topmost directory that B<mr> should work in. The default is
-the current working directory. B<mr> will operate on all registered
-repositories at or under the directory.

=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
-"$@". B<mr> cds into the repository directory before running
-a command, except for the "checkout" command, which is run in the parent
-of the repository directory, since the repository isn't checked out yet.
+"$@". 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.
+The "MR_REPO" environment variable is set to the path to the top of the
+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
-There are two 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
should avoid chaining from repositories with untrusted committers.)
-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".
+=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.
- [src]
- checkout = svn co svn://svn.example.com/src/trunk src
- chain = true
+=item lib
- [src/linux-2.6]
- # only check this out on kodama
- skip = test $(hostname) != kodama
- checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
+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 for other commands
+to use.
