;; Supported version-control systems presently include SCCS, RCS, and CVS.
-;; The RCS lock-stealing code doesn't work right unless you use RCS 5.6.2
-;; or newer. Currently (January 1994) that is only a beta test release.
+;;
+;; Some features will not work with old RCS versions. Where
+;; appropriate, VC finds out which version you have, and allows or
+;; disallows those features (stealing locks, for example, works only
+;; from 5.6.2 onwards).
;; Even initial checkins will fail if your RCS version is so old that ci
;; doesn't understand -t-; this has been known to happen to people running
;; NExTSTEP 3.0.
;;
-;; The RCS code assumes strict locking. You can support the RCS -x option
-;; by adding pairs to the vc-master-templates list.
+;; You can support the RCS -x option by adding pairs to the
+;; vc-master-templates list.

;; Proper function of the SCCS diff commands requires the shellscript vcdiff
;; to be installed somewhere on Emacs's path for executables.
