;; 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.
