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