;;; Commentary:
;; This emacs lisp program can be used to create an emacs lisp file that
;; defines the TPU-edt keypad for emacs running on x-windows. Please read
;; the "Usage" AND "Known Problems" sections before attempting to run this
;; program.
;;; Usage:
;; Simply load this file into the X-windows version of emacs (version 19)
;; using the following command.
;; emacs -q -l tpu-mapper.el
;; The "-q" option prevents loading of your .emacs file (commands therein
;; might confuse this program).
;; An instruction screen showing the TPU-edt keypad will be displayed, and
;; you will be prompted to press the TPU-edt editing keys. Tpu-mapper uses
;; the keys you press to create an emacs lisp file that will define a
;; TPU-edt keypad for your X server. You can even re-arrange the standard
;; EDT keypad to suit your tastes (or to cope with those silly Sun and PC
;; keypads).
;; Finally, you will be prompted for the name of the file to store the key
;; definitions. If you chose the default, TPU-edt will find it and load it
;; automatically. If you specify a different file name, you will need to
;; set the variable "tpu-xkeys-file" before loading TPU-edt. Here's how
;; you might go about doing that in your .emacs file.
;; (setq tpu-xkeys-file (expand-file-name "~/.my-emacs-x-keys"))
;; (load "tpu-edt")
;;; Known Problems:
;; Sometimes, tpu-mapper will ignore a key you press, and just continue to
;; prompt for the same key. This can happen when your window manager sucks
;; up the key and doesn't pass it on to emacs, or it could be an emacs bug.
;; Either way, there's nothing that tpu-mapper can do about it. You must
;; press RETURN, to skip the current key and continue. Later, you and/or
;; your local X guru can try to figure out why the key is being ignored.

This program prompts you to press keys to create a custom keymap file
for use with the x-windows version of emacs and TPU-edt.
Start by pressing the RETURN key, and continue by pressing the keys
specified in the mini-buffer. You can re-arrange the TPU-edt keypad
by pressing any key you want at any prompt. If you want to entirely
omit a key, just press RETURN at the prompt.
Here's a picture of the standard TPU/edt keypad for reference:
