=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, and bzr 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
working directory. Or, if you are in a subdirectory of a repository that
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
+
+Adds, modifies, removes, or prints a value from the 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
+
=item help
Displays this help.
"mr st" is equivilant to "mr status", and "mr up" is equivilant to "mr
update"
-Additional parameters can be passed to other commands than "commit", they
-will be 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.
+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
chain = true
[src/linux-2.6]
- checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
+ checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git &&
+ cd linux-2.6 &&
+ git checkout -b mybranch origin/master
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.
=item skip
If the "skip" parameter is set and its command returns nonzero, then B<mr>
-will skip acting on that repository.
+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") -lt 12 ]
=item chain
will try to load a .mrconfig file from the root of the repository. (You
should avoid chaining from repositories with untrusted committers.)
+=item deleted
+
+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.
+
=item lib
The "lib" parameter can specify some shell code that will be run before each
=cut
