2 * jconfig.txt
3 *
4 * This file was part of the Independent JPEG Group's software:
5 * Copyright (C) 1991-1994, Thomas G. Lane.
6 * It was modified by The libjpeg-turbo Project to include only code relevant
7 * to libjpeg-turbo.
8 * For conditions of distribution and use, see the accompanying README.ijg
9 * file.
10 *
11 * This file documents the configuration options that are required to
12 * customize the JPEG software for a particular system.
13 *
14 * The actual configuration options for a particular installation are stored
15 * in jconfig.h. On many machines, jconfig.h can be generated automatically
16 * or copied from one of the "canned" jconfig files that we supply. But if
17 * you need to generate a jconfig.h file by hand, this file tells you how.
18 *
19 * DO NOT EDIT THIS FILE --- IT WON'T ACCOMPLISH ANYTHING.
20 * EDIT A COPY NAMED JCONFIG.H.
