=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 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> 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.
-B<mr> cds into and operates on all registered repsitories at or below your
+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,
-The predefined commands should be fairly familiar to users of any revision
+These predefined commands should be fairly familiar to users of any revision
control system:
=over 4
Show the commit log.

+
+These commands are also available:
+
+=over 4
+
=item list (or ls)
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.
+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.
+
+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
-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.
+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.
For example, to add (or edit) a repository in src/foo:
mr config src/foo checkout="svn co svn://example.com/foo/trunk foo"
+To show the command that mr uses to update the repository in src/foo:
+
+ 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
Be verbose.
+=item -s
+
+Expand the statistics line displayed at the end to include information
+about exactly which repositories failed and were skipped, if any.
+
+=item -n
+
+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.

- 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.
+"#" are comments. Values can be continued to the following line by
+indenting the line with whitespace.
The "DEFAULT" section allows setting default values for the sections that
come after it.
paths.
Within a section, each parameter defines a shell command to run to handle a
-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".
+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
"$@". 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.
+repository. (For the "register" action, "MR_REPO" is instead set to the
+basename of the directory that should be created when checking the
+repository out.)
+
+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:
=item skip
-If the "skip" parameter is set and its command returns nonzero, then B<mr>
-will skip acting on that repository.
+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.
+
+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.
+
+ 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 nonzero, then B<mr>
+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.)
-=item deleted
+=item include
+
+If the "include" parameter is set, its command is ran, and should output
+additional mrconfig file content. The content is included as if it were
+part of the including file.
-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.
+Unlike all other parameters, this parameter does not need to be placed
+within a section.
=item lib
=back
+When looking for a command to run for a given action, mr first looks for
+a parameter with the same name as the action. If that is not found, it
+looks for a parameter named "rcs_action" (substituting in the name of the
+revision control system and the action). The name of the revision control
+system is itself determined by running each defined "rcs_test" action,
+until one succeeds.
+
+Internally, mr has settings for "git_update", "svn_update", etc. To change
+the action that is performed for a given revision control system, you can
+override these rcs specific actions. To add a new revision control system,
+you can just add rcs specific actions for it.
