;;;; File: lyskom-rest.el

;;;; This is the rest of what was once the entire source code of the
;;;; client. Now most of the source resides in other files. Eventually
;;;; the functions in here will be distributed out to other files.
;;;; Below follows the original header of the LysKOM elisp client:
;;;;
;;;; ================================================================
;;;;
;;;; Simple LysKOM elisp client.
;;;;
;;;; Originally written by Per Cederqvist.
;;;;
;;;; Heavily hacked by:
;;;;    Thomas Bellman
;;;;    Linus Tolke
;;;;    Inge Wallin
;;;;   and others.
;;;;
;;;; Some ideas stolen from lpmud.el written by Lars Willf|r and Thomas Bellman
;;;;
;;;; Conventions:
;;;;
;;;;    All functions, variables etc follow one of these conventions:
;;;;		lyskom-		general functions.
;;;;		cache-		cache-routines.
;;;;		initiate-	call a service. (Might look up in cache)
;;;;		kom-		user kommands.
;;;;		lyskom-parse-	parse (part of) a reply from the server.
;;;;				these are found in parse.el
;;;;		lyskom-edit-	Things related to the editing of texts.
;;;;		{lyskom,kom}-edit-options-
;;;;				things related to editing options
;;;;				(found in flags.el)
;;;;		{lyskom,kom}-prioritize-
;;;;				things related to the prioritize
;;;;				buffer. The file is prioritize.el
;;;;		{lyskom,kom}-{completing-read,completing,complete}-
;;;;				things related to
;;;;				lyskom-completing-read. Found in
;;;;				completing-read.el 
;;;;		lyskom-*-hook   hooks.
;;;;
;;;;    Three plus-signs (+++) in the code marks a place where more
;;;;    work is needed.
