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! ********** | |
33 | ||
34 | ;; This file has been obsolete and unsupported since Emacs 23.1. | |
35 | ||
36 | ||
37 | ;; The home page of the Meta-CVS version control system is at | |
38 | ;; | |
39 | ;; http://users.footprints.net/~kaz/mcvs.html | |
40 | ;; | |
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 | |
47 | ;; | |
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. | |
51 | ;; | |
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 | |
60 | ||
61 | ;;; Bugs: | |
62 | ||
63 | ;; - Retrieving tags doesn't filter `cvs update' output and thus | |
64 | ;; parses bogus filenames. Don't know if it harms. | |
