+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,

+Internally, mr has settings for "git_update", "svn_update", etc. To change

+override these rcs specific actions. To add a new revision control system,
