/*
* Copyright (c) 1988-1997 Sam Leffler
* Copyright (c) 1991-1997 Silicon Graphics, Inc.
*
* Revised: 2/18/01 BAR -- added syntax for extracting single images from
* multi-image TIFF files.
*
* New syntax is: sourceFileName,image#
*
* image# ranges from 0..<n-1> where n is the # of images in the file.
* There may be no white space between the comma and the filename or
* image number.
*
* Example: tiffcp source.tif,1 destination.tif
*
* Copies the 2nd image in source.tif to the destination.
