 * This file illustrates how to use the IJG code as a subroutine library
 * to read or write JPEG image files.  You should look at this code in
 * conjunction with the documentation file libjpeg.txt.
 *
 * This code will not do anything useful as-is, but it may be helpful as a
 * skeleton for constructing routines that call the JPEG library.
