+ *
+ * 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.
