;;; 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 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).
;; 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.
;;; Bugs:
;; - Extracting an old version seems not to recognize encoding correctly.
;; That's probably because it's done via a process rather than a file.
;;; Todo:
;; ******** FIX THE DOCUMENTATION *********
;;
;; - 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.
;; - allow cvs-confirm-removals to force always confirmation.
;; - cvs-checkout should ask for a revision (with completion).
;; - removal confirmation should allow specifying another file name.
;;
;; - hide fileinfos without getting rid of them (will require ewok work).
;; - add toolbar entries
;; - marking
;; marking directories should jump to just after the dir.
;; allow (un)marking directories at a time with the mouse.
;; allow cvs-cmd-do to either clear the marks or not.
;; add a "marks active" notion, like transient-mark-mode does.
;; - liveness indicator
;; - indicate in docstring if the cmd understands the `b' prefix(es).
;; - call smerge-mode when opening CONFLICT files.
;; - have vc-checkin delegate to cvs-mode-commit when applicable
;; - higher-level CVS operations
;; cvs-mode-rename
;; cvs-mode-branch
;; - module-level commands
;; add support for parsing 'modules' file ("cvs co -c")
;; cvs-mode-rcs2log
;; cvs-rdiff
;; cvs-release
;; cvs-import
;; C-u M-x cvs-checkout should ask for a cvsroot
;; cvs-mode-handle-new-vendor-version
;; - checks out module, or alternately does update join
;; - does "cvs -n tag LAST_VENDOR" to find old files into *cvs*
;; cvs-export
;; (with completion on tag names and hooks to help generate full releases)
;; - display stickiness information. And current CVS/Tag as well.
;; - write 'cvs-mode-admin' to do arbitrary 'cvs admin' commands
;; Most interesting would be version removal and log message replacement.
;; The last one would be neat when called from log-view-mode.
;; - cvs-mode-incorporate
;; It would merge in the status from one *cvs* buffer into another.
;; This would be used to populate such a buffer that had been created with
;; a `cvs {update,status,checkout} -l'.
;; - cvs-mode-(i)diff-other-{file,buffer,cvs-buffer}
;; - offer the choice to kill the process when the user kills the cvs buffer.
;; right now, it's killed without further ado.
;; - make `cvs-mode-ignore' allow manually entering a pattern.
;; to which dir should it apply ?
;; - cvs-mode-ignore should try to remove duplicate entries.
;; - maybe poll/check CVS/Entries files to react to external `cvs' commands ?
;; - some kind of `cvs annotate' support ?
;; but vc-annotate can be used instead.
;; - proper `g' that passes safe args and uses either cvs-status or cvs-examine
;; maybe also use cvs-update depending on I-don't-know-what.
;; - add message-levels so that we can hide some levels of messages
