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.
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.
