;; WARNING:
;; --------
;;
;; % p4 edit foo.c
;; ... make changes to foo.c in emacs
;; % p4 submit
;; ... keep the writable copy of foo.c in emacs. Start making changes
;; to it. Discover that you can't save it. If you do M-x:p4-edit,
;; you'll lose your changes. You need to do a 'p4 edit' at the
;; command-line.
;;
;; NOTES:
;; ------
;;
;; It is best if you take this file and byte compile it. To do that, you
;; need to do the following:
;;
;; % emacs -batch -f batch-byte-compile /full/path/to/file/p4.el
;;
;; This creates a binary file p4.elc in the path. Add the path to your
;; load-path variable in .emacs like this:
;;
;; (setq load-path (cons "/full/path/to/file" load-path))
;;
;; Then add the library like this:
;;
;; (load-library "p4")
;;
;;; Code:
