26 ;; ********** READ THIS! **********
28 ;; This file apparently does not work with the new (as of Emacs 23)
29 ;; VC code. Use at your own risk. Please contact emacs-devel if you
30 ;; can maintain this file and update it to work correctly.
32 ;; ********** READ THIS! **********
34 ;; This file has been obsolete and unsupported since Emacs 23.1.
37 ;; The home page of the Meta-CVS version control system is at
39 ;; http://users.footprints.net/~kaz/mcvs.html
41 ;; This is derived from vc-cvs.el as follows:
42 ;; - cp vc-cvs.el vc-mcvs.el
43 ;; - Replace CVS/ with MCVS/CVS/
44 ;; - Replace 'CVS with 'MCVS
45 ;; - Replace -cvs- with -mcvs-
46 ;; - Replace most of the rest of CVS to Meta-CVS
48 ;; Then of course started the hacking. Only a small part of the code
49 ;; has been touched and not much more than that was tested, so if
50 ;; you bump into a bug, don't be surprised: just report it to me.
52 ;; What has been partly tested:
53 ;; - C-x v v to start editing a file that was checked out with CVSREAD on.
54 ;; - C-x v v to commit a file
55 ;; - C-x v =
56 ;; - C-x v l
57 ;; - C-x v i
58 ;; - C-x v g
59 ;; - M-x vc-rename-file RET
61 ;;; Bugs:
63 ;; - Retrieving tags doesn't filter `cvs update' output and thus
64 ;; parses bogus filenames. Don't know if it harms.
66 ;;; Code:
68 (eval-when-compile (require 'vc))
69 (require 'vc-cvs)
