+ * Revision History:
+ * 10-Jan-89: Created.
+ * 06-Mar-90: Change to byte encoded rasterfiles.
+ *	      fix bug in call to ReadScanline().
+ *	      fix bug in CVT() macro.
+ *	      fix assignment of td, (missing &).
+ *
+ * Description:
+ *   This program takes a MicroSoft/Aldus "Tagged Image File Format" image or
+ * "TIFF" file as input and writes a Sun Rasterfile [see rasterfile(5)].  The
+ * output file may be standard output, but the input TIFF file must be a real
+ * file since seek(2) is used.
