+;;; Commentary:
+
+;; ********** READ THIS! **********
+;;
+;; This file apparently does not work with the new (as of Emacs 23)
+;; VC code. Use at your own risk. Please contact emacs-devel if you
+;; can maintain this file and update it to work correctly.
+;;
+;; ********** READ THIS! **********
+
+;; This file has been obsolete and unsupported since Emacs 23.1.
+
+
+;; The home page of the Meta-CVS version control system is at
+;;
+;; http://users.footprints.net/~kaz/mcvs.html
+;;
+;; This is derived from vc-cvs.el as follows:
+;; - cp vc-cvs.el vc-mcvs.el
+;; - Replace CVS/ with MCVS/CVS/
+;; - Replace 'CVS with 'MCVS
+;; - Replace -cvs- with -mcvs-
+;; - Replace most of the rest of CVS to Meta-CVS
+;;
+;; Then of course started the hacking. Only a small part of the code
+;; has been touched and not much more than that was tested, so if
+;; you bump into a bug, don't be surprised: just report it to me.
+;;
+;; What has been partly tested:
+;; - C-x v v to start editing a file that was checked out with CVSREAD on.
+;; - C-x v v to commit a file
+;; - C-x v =
+;; - C-x v l
+;; - C-x v i
+;; - C-x v g
+;; - M-x vc-rename-file RET
+
+;;; Bugs:
+
+;; - Retrieving tags doesn't filter `cvs update' output and thus
+;; parses bogus filenames. Don't know if it harms.
