+;; This simply adds a menu of the common CVS commands to the menubar and to
+;; the right mouse button.  Clicking right moves point, and then pops up a
+;; menu from which commands can be executed.
+;; 
+;; This could stand to be a lot more clever: for example, the "Commit Changes"
+;; command should only be active on files for which there is something to
+;; commit.  Also, some indication of which files the command applies to
+;; (especially in the presence of multiple marked files) would be nice.
+;;
+;; Middle-click runs find-file.
