/*
 * fontedit
 *	Fonteditor for VT220
 *
 *  BUGS:
 *	o Cursor motion is less than optimal (but who cares at 9600),
 *
 *  COMPILE:
 *	cc -O fontedit.c -o fontedit
 *      (use Makefile)
 *
 *	Copyright (c) 1987 by Greg Franks.
 *
 *	Permission is granted to do anything you want with this program
 *	except claim that you wrote it.
 *
 *
 *      REVISION HISTORY:
 *
 *      Nov 21, 1987 - Fixed man page to say "Fontedit" instead of "Top"
 *      Nov 22, 1987 - Added BSD Compatible ioctl, turned cursor on/off
 *                     - eap@bucsf.bu.edu
