5 * Copyright (c) 1991-1997 Silicon Graphics, Inc.
6 *
7 * Revised: 2/18/01 BAR -- added syntax for extracting single images from
8 * multi-image TIFF files.
9 *
10 * New syntax is: sourceFileName,image#
11 *
12 * image# ranges from 0..<n-1> where n is the # of images in the file.
13 * There may be no white space between the comma and the filename or
14 * image number.
15 *
16 * Example: tiffcp source.tif,1 destination.tif
17 *
18 * Copies the 2nd image in source.tif to the destination.
