- * HISTORY:
- *
- * 17/12/93 - Version 0.1 released.
- *
- * 19/12/93 - menu will now scroll if there are more items than can fit
- * on the screen.
- * - added 'checklist', a dialog box with a list of options that
- * can be turned on or off. A list of options that are on is
- * returned on exit.
- *
- * 20/12/93 - Version 0.15 released.
- *
- * 29/12/93 - Incorporated patch from Patrick J. Volkerding
- * (volkerdi@mhd1.moorhead.msus.edu) that made these changes:
- * - increased MAX_LEN to 2048
- * - added 'infobox', equivalent to a message box without pausing
- * - added option '--clear' that will clear the screen
- * - Explicit line breaking when printing prompt text can be
- * invoked by real newline '\n' besides the string "\n"
- * - an optional parameter '--title <string>' can be used to
- * specify a title string for the dialog box
- *
- * 03/01/94 - added 'textbox', a dialog box for displaying text from a file.
- * - Version 0.2 released.
- *
- * 04/01/94 - some fixes and improvements for 'textbox':
- * - fixed a bug that will cause a segmentation violation when a
- * line is longer than MAX_LEN characters. Lines will now be
- * truncated if they are longer than MAX_LEN characters.
- * - removed wrefresh() from print_line(). This will increase
- * efficiency of print_page() which calls print_line().
- * - display current position in the form of percentage into file.
- * - Version 0.21 released.
- *
- * 05/01/94 - some changes for faster screen update.
- *
- * 07/01/94 - much more flexible color settings. Can use all 16 colors
- * (8 normal, 8 highlight) of the Linux console.
- *
- * 08/01/94 - added run-time configuration using configuration file.
- *
- * 09/01/94 - some minor bug fixes and cleanups for menubox, checklist and
- * textbox.
- *
- * 11/01/94 - added a man page.
- *
- * 13/01/94 - some changes for easier porting to other Unix systems (tested
- * on Ultrix, SunOS and HPUX)
- * - Version 0.3 released.
- * 04/08/95 - Complete rewriten in C++. It is no more the official
- * dialog program. Not even sure its still work. The goal
- * was to turn all this into a library.
