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
repository. It supports any combination of subversion, git, cvs, mercurial,
-bzr, darcs and fossil repositories, and support for other version
+bzr, darcs, fossil and veracity repositories, and support for other version
control systems can easily be added.
B<mr> cds into and operates on all registered repositories at or below your
as well as look for a F<.mrconfig> file in the current directory, or in one
of its parent directories.
+=item -f

+=item --force
+
+Force mr to act on repositories that would normally be skipped due to their
+configuration.

=item -v
=item --verbose
Another way to use skip is for a lazy checkout. This makes mr skip
operating on a repo unless it already exists. To enable the
-repo, you have to explicitly check it out (using "mr -d foo checkout").

=item lib
-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.

+
+Unlike most other parameters, this can be specified multiple times, in
+which case the chunks of shell code are accumulatively concatenated
+together.
=item fixups
like permissions fixups, or other tweaks to the repository content,
whenever the repository is changed.
-=item pre_ and post_
-
-If a "pre_action" parameter is set, its command is run before mr performs the
-specified action. Similarly, "post_action" parameters are run after mr
-successfully performs the specified action. For example, "pre_commit" is
-run before committing; "post_update" is run after updating.

+=item VCS_action
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 "VCS_action" (substituting in the name of the
-version control system and the action). The name of the version control
-system is itself determined by running each defined "VCS_test" action,
-until one succeeds.
+version control system and the action).
Internally, mr has settings for "git_update", "svn_update", etc. To change
the action that is performed for a given version control system, you can
override these VCS specific actions. To add a new version control system,
you can just add VCS specific actions for it.

+
+=item _append
+
+Any parameter can be suffixed with C<_append>, to add an additional value
+to the existing value of the parameter. In this way, actions
+can be constructed accumulatively.
