;; This is the interface for pari under emacs.
;; The main commands in this file are :
;; M-x gp Opens a buffer for interaction with gp and then starts gp.
;; C-u M-x gp Like M-x gp, but prompts for command line arguments.
;; M-x gpman Displays the gp-pari manual using any dvi preview program.
;; All functions of gp are preserved.
;; Version 2.38 (2-July-2000)
;; The original pari.el was written by Annette Hoffman.
;; Modified by David Carlisle (JANET: carlisle@uk.ac.man.cs).
;; Modified by Karim Belabas (belabas@math.u-bordeaux.fr) for gp 2.xxx.
;; Modified by Olivier Ramare (ramare@gat.univ-lille1.fr).
;; Maintainer (22-November-1998): Olivier Ramare (ramare@agat.univ-lille1.fr).
;; See pariemacs.txt for more details.
;; KNOWN DEFICIENCIES:
;; -- The hilit part may have troubles with `}'. A `}' followed by
;; a newline indicates the end of a function-definition starting with
;; `{'. Spaces, or tab are *not* allowed. So if you use `}' as a string
;; DON'T have it followed by a newline.
;; This file is split in six parts :
;; PART I : MAIN CONSTANTS (contains a macro).
;; Some of them may have to be modified by the user.
;; The macro 'gp-defcustom is defined there.
;; PART II : KEYMAPS AND OTHER VARIABLES
;; including the two macros 'gp-hilit-init and
;; 'gp-tell-hilit-about-patterns. Also the substitution
;; 'gp-setup is being defined there.
;; PART III : gp-mode AND gp-script-mode
;; PART IV : GENERAL FUNCTIONS
;; Contains: HANDLING THE WINDOWS ...
;; THE GP PROCESS
;; META-COMMANDS
;; GP COMPLETION FUNCTIONS
;; COMPLETION FILES
;; TeX MANUAL
;; GP HELP MODE
;; TeX AND USUAL INFO
;; PART V : HILIGHTING
;; PART VI : MENU-BAR
;; Contains: MENU BUILDERS (contains 3 constants)
;; MENU-BAR ITEM USED IN GP-SCRIPT-MODE
;; MENU-BAR ITEM USED IN GP-MODE

;; Note that this order is not random! In order for the compilation
