| 7 | * Purpose: This program demonstrates the use of the 'curses' library |
| 8 | * for the creation of (simple) menu-operated programs. |
| 9 | * In the PDCurses version, use is made of colors for the |
| 10 | * highlighting of subwindows (title bar, status bar etc). |
| 11 | * |
| 12 | * Acknowledgement: some ideas were borrowed from Mark Hessling's |
| 13 | * version of the 'testcurs' program. |
