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,
+repository. It supports any combination of subversion, git, cvs, mecurial,
bzr and darcs repositories, and support for other revision control systems can
easily be added.
=item commit (or ci)
Commits changes to each repository. (By default, changes are pushed to the
-remote repository too, when using distributed systems like git.)
+remote repository too, when using distributed systems like git. If you
+don't like this default, you can change it in your .mrconfig, or use record
+instead.)
+
+The optional -m parameter allows specifying a commit message.
+
+=item record
+
+Records changes to the local repository, but does not push them to the
+remote repository. Only supported for distributed revision control systems.
The optional -m parameter allows specifying a commit message.

-Actions can be abbreviated to any unambiguous subsctring, so
-"mr st" is equivilant to "mr status", and "mr up" is equivilant to "mr
+Actions can be abbreviated to any unambiguous substring, so
+"mr st" is equivalent to "mr status", and "mr up" is equivalent to "mr

Additional parameters can be passed to most commands, and are passed on
Be verbose.
+=item -q
+
+Be quiet.
+
=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
+=item -i
+
+Interactive mode. If a repository fails to be processed, a subshell will be
+started which you can use to resolve or investigate the problem. Exit the
+subshell to continue the mr run.
+
+=item -n [number]
-Just operate on the repository for the current directory, do not
-recurse into deeper repositories.
+If no number if specified, just operate on the repository for the current
+directory, do not recurse into deeper repositories.
-=item -j number
+If a number is specified, will recurse into repositories at most that many
+subdirectories deep. For example, with -n 2 it would recurse into ./src/foo,
+but not ./src/packages/bar.
-Run the specified number of jobs in parallel. This can greatly speed up
-operations such as updates. It is not recommended for interactive
-operations.
+=item -j [number]
+
+Run the specified number of jobs in parallel, or an unlimited number of jobs
+with no number specified. This can greatly speed up operations such as updates.
+It is not recommended for interactive operations.
+
+Note that running more than 10 jobs at a time is likely to run afoul of
+ssh connection limits. Running between 3 and 5 jobs at a time will yeild
+a good speedup in updates without loading the machine too much.

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. The "MR_CONFIG" environment variable is set to the .mrconfig file
+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.
(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 = test `whoami` != joey
skip = [ "$1" = update ] && ! hours_since "$1" 12
=item order
will try to load a .mrconfig file from the root of the repository. (You
should avoid chaining from repositories with untrusted committers.)
+=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.
+
+Unlike all other parameters, this parameter does not need to be placed
+within a section.
+
=item lib
The "lib" parameter can specify some shell code that will be run before each
=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.
