/*
* Author : P.J. Kunst <kunst@prl.philips.nl>
* Date : 1993-02-25
*
* Purpose: This program demonstrates the use of the 'curses' library
* for the creation of (simple) menu-operated programs.
* In the PDCurses version, use is made of colors for the
* highlighting of subwindows (title bar, status bar etc).
*
* Acknowledgement: some ideas were borrowed from Mark Hessling's
* version of the 'testcurs' program.
