;;; Commentary:
;; Uses the Emacs 19 terminal initialization features --- won't work with 18.
;; Handles all VT100 clones, including the Apollo terminal. Also handles
;; the VT200 --- its PF- and arrow- keys are different, but all those
;; are really set up by the terminal initialization code, which mines them
;; out of termcap. This package is here to define the keypad comma, dash
;; and period (which aren't in termcap's repertoire) and the function for
;; changing from 80 to 132 columns & vv.
;;; Code:
;; Set up function-key-map entries that termcap and terminfo don't know.
