Some months ago, I expressed frustration here with the direction
upstream was taking gnuserv, and the fact that the Debian maintainer
seemed happy with it. Since then, there has been a new Debian
maintainer, but other than that nothing significant has happened. So
I decided to drop gnuserv altogether and switch back to
emacsserver/emacsclient. Of course, that left me without gnudoit
functionality, so I wrote this little hack of my own. Comments are
invited, especially about potential security hazards.

;;; Commentary:
X
;; The purpose of this library is to provide a remote Lisp evaluation
;; functionality similar to what is available in the gnuserv package
;; (which is getting more and more optimized for XEmacs, so I gave up
;; on it).
X
;; In order to use it, you must put this code in your .emacs file.
X
;; (load-library "edoit")
;; (server-start)
X
;; You can then send remote commands to Emacs by running the program
;; "edoit". For example,
;;
;; edoit '(gnus)'
;;
;; Type "edoit -h" (sorry, no Info manual yet) for details.
