;;; Commentary:
-;; PCL-CVS is a front-end to the CVS version control system. For people
-;; familiar with VC, it is somewhat like VC-dired: it presents the status of
-;; all the files in your working area and allows you to commit/update several
-;; of them at a time. Compared to VC-dired, it is considerably better and
-;; faster (but only for CVS).
+;; PCL-CVS is a front-end to the CVS version control system.
+;; It presents the status of all the files in your working area and
+;; allows you to commit/update several of them at a time.
+;; Compare with the general Emacs utility vc-dir, which tries
+;; to be VCS-agnostic. You may find PCL-CVS better/faster for CVS.
;; PCL-CVS was originally written by Per Cederqvist many years ago. This
;; version derives from the XEmacs-21 version, itself based on the 2.0b2
;; version (last release from Per). It is a thorough rework.
-;; Contrary to what you'd expect, PCL-CVS is not a replacement for VC but only
-;; for VC-dired. As such, I've tried to make PCL-CVS and VC interoperate
-;; seamlessly (I also use VC).
+;; PCL-CVS is not a replacement for VC, but adds extra functionality.
+;; As such, I've tried to make PCL-CVS and VC interoperate seamlessly
+;; (I also use VC).
;; To use PCL-CVS just use `M-x cvs-examine RET <dir> RET'.
;; There is a TeXinfo manual, which can be helpful to get started.
;; - rework the displaying of error messages.
;; - allow to flush messages only
;; - allow to protect files like ChangeLog from flushing
-;; - automatically cvs-mode-insert files from find-file-hook
-;; (and don't flush them as long as they are visited)
;; - query the user for cvs-get-marked (for some cmds or if nothing's selected)
;; - don't return the first (resp last) FI if the cursor is before
;; (resp after) it.
