27 ;; The home page of the Arch version control system is at
29 ;; http://www.gnuarch.org/
31 ;; This is derived from vc-mcvs.el as follows:
32 ;; - cp vc-mcvs.el vc-arch.el and then M-% mcvs RET arch RET
34 ;; Then of course started the hacking.
36 ;; What has been partly tested:
38 ;; - C-x v = without any prefix arg.
39 ;; - C-x v v to commit a change to a single file.
43 ;; - *VC-log*'s initial content lacks the `Summary:' lines.
44 ;; - All files under the tree are considered as "under Arch's control"
45 ;; without regards to =tagging-method and such.
46 ;; - Files are always considered as `edited'.
47 ;; - C-x v l does not work.
48 ;; - C-x v i does not work.
49 ;; - C-x v ~ does not work.
50 ;; - C-x v u does not work.
51 ;; - C-x v s does not work.
52 ;; - C-x v r does not work.
53 ;; - VC directory listings do not work.
