-
-;;; Commentary:
-
-;; The purpose of this library is to handle command line arguments
-;; when you resume an existing Emacs job.
-
-;; In order to use it, you must put this code in your .emacs file.
-
-;; (add-hook 'suspend-hook 'resume-suspend-hook)
-;; (add-hook 'suspend-resume-hook 'resume-process-args)
-
-;; You can't get the benefit of this library by using the `emacs' command,
-;; since that always starts a new Emacs job.  Instead you must use a
-;; command called `edit' which knows how to resume an existing Emacs job
-;; if you have one, or start a new Emacs job if you don't have one.
-
-;; To define the `edit' command, run the script etc/emacs.csh (if you use CSH),
-;; or etc/emacs.bash if you use BASH.  You would normally do this in your
-;; login script.
-
-;; Stephan Gildea suggested bug fix (address@hidden).
-;; Ideas from Michael DeCorte and other people.
