 Actions can be abbreviated to any unambiguous subsctring, so
 "mr st" is equivilant to "mr status".
 
+B<mr> operates on all registered repsitories at or below your working
+directory. Or, if you are in a subdirectory of a repository, it will act on
+only that repository.
+
+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.
