    *
    *   Functions: This file contains
    *      main
    *
    *   Purpose:
    *      This is the main routine of a
    *      stand alone program that prints
    *      TIFF images to the HP DeskJet printer
    *      graphically.
    *
    *      You can run this program using either
    *      the command line or via menus.
    *
    *      cipspr image-name [help -i -h -e -il -ie -t]
    *
    *      cipspr help - gives you a usage message
    *
    *      cipspr - gives you the menu interface
    *
    *      cipspr image-name - displays that image
    *
    *      Options:
    *         -i  - invert the image when displaying
    *         -h  - show the histogram
    *         -e  - use histogram equalization
    *         -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_menu_for_display_image
    *      djet.c - print_graphics_image
