+;;; 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.
+(load "term/lk201" nil t)
+
;;; Controlling the screen width.
