31 | ;; This is derived from vc-cvs.el as follows: |
32 | ;; - cp vc-cvs.el vc-mcvs.el | |
33 | ;; - Replace CVS/ with MCVS/CVS/ | |
34 | ;; - Replace 'CVS with 'MCVS | |
35 | ;; - Replace -cvs- with -mcvs- | |
36 | ;; - Replace most of the rest of CVS to Meta-CVS | |
37 | ;; | |
38 | ;; Then of course started the hacking. Only a small part of the code | |
39 | ;; has been touched and not much more than that was tested, so if | |
40 | ;; you bump into a bug, don't be surprised: just report it to me. | |
41 | ;; | |
42 | ;; What has been partly tested: | |
43 | ;; - C-x v v to start editing a file that was checked out with CVSREAD on. | |
44 | ;; - C-x v v to commit a file | |
45 | ;; - C-x v = | |
46 | ;; - C-x v l | |
47 | ;; - C-x v i | |
48 | ;; - C-x v g | |
4a97caca | 49 | ;; - M-x vc-rename-file RET |
