       *   Functions: This file contains
       *      main
       *
       *   Purpose:
       *      This is the main routine of a
       *      stand alone program that displays
       *      TIFF images.
       *
       *      You can run this program using either
       *      the command line or via menus.
       *
       *      show image-name [help -i -h -il -ie -t]
       *
       *      show help - gives you a usage message
       *
       *      show - gives you the menu interface
       *
       *      show image-name - displays that image
       *
       *      Options:
       *         -i  - invert the image when displaying
       *         -h  - show the histogram
       *         -il - specify initial line
       *         -ie - specify initial element
       *         -t  - means the words following -t
       *               are a title to display below
       *               the image.  Always put the -t
       *               as the final option.
       *
       *   External Calls:
       *      gin.c - get_image_name
       *      rtiff.c - read_tiff_image
       *      tiff.c - read_tiff_header
       *      display.c - display_image
       *                  display_menu_for_display_image
       *      mymsc.c - my_clear_text_screen
