+ *
+ * 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
+ * Added backtitle option
+ * - Version 0.4 released.
+ *
+ * 10/10/94 - Patches by Marc Ewing - marc@redhat.com
+ * Added --separate-output
+ * Added init val to inputbox
+ * Added guage widget
