*
* Revision History:
* 11-Jan-89: Created.
* 06-Mar-90: fix bug in SCALE() macro.
* got rid of xres and yres, (they weren't working anyways).
* fixed bpsl calculation.
* 25-Nov-99: y2k fix (year as 1900 + tm_year) <mike@onshore.com>
*
* Description:
* This program takes a Sun Rasterfile [see rasterfile(5)] as input and
* writes a MicroSoft/Aldus "Tagged Image File Format" image or "TIFF" file.
* The input file may be standard input, but the output TIFF file must be a
* real file since seek(2) is used.
