*
*
* 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.
*
* 08/06/94 - Patches by Stuart Herbert - S.Herbert@shef.ac.uk
* Fixed attr_clear and the textbox stuff to work with ncurses 1.8.5
* Fixed the wordwrap routine - it'll actually wrap properly now
* Added a more 3D look to everything - having your own rc file could
* prove 'interesting' to say the least :-)
* Added radiolist option
* - Version 0.4 released.
*
* 09/28/98 - Patches by Anatoly A. Orehovsky - tolik@mpeks.tomsk.su
* Added ftree and tree options
*
