  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.

 +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.
