+IJG JPEG LIBRARY: FILE LIST
+
+Copyright (C) 1994-1998, Thomas G. Lane.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+Here is a road map to the files in the IJG JPEG distribution. The
+distribution includes the JPEG library proper, plus two application
+programs ("cjpeg" and "djpeg") which use the library to convert JPEG
+files to and from some other popular image formats. A third application
+"jpegtran" uses the library to do lossless conversion between different
+variants of JPEG. There are also two stand-alone applications,
+"rdjpgcom" and "wrjpgcom".
+
+
+THE JPEG LIBRARY
+================
+
+Include files:
+
+jpeglib.h JPEG library's exported data and function declarations.
+jconfig.h Configuration declarations. Note: this file is not present
+ in the distribution; it is generated during installation.
+jmorecfg.h Additional configuration declarations; need not be changed
+ for a standard installation.
+jerror.h Declares JPEG library's error and trace message codes.
+jinclude.h Central include file used by all IJG .c files to reference
+ system include files.
+jpegint.h JPEG library's internal data structures.
+jchuff.h Private declarations for Huffman encoder modules.
+jdhuff.h Private declarations for Huffman decoder modules.
+jdct.h Private declarations for forward & reverse DCT subsystems.
+jmemsys.h Private declarations for memory management subsystem.
+jversion.h Version information.
+
+Applications using the library should include jpeglib.h (which in turn
+includes jconfig.h and jmorecfg.h). Optionally, jerror.h may be included
+if the application needs to reference individual JPEG error codes. The
+other include files are intended for internal use and would not normally
+be included by an application program. (cjpeg/djpeg/etc do use jinclude.h,
+since its function is to improve portability of the whole IJG distribution.
+Most other applications will directly include the system include files they
+want, and hence won't need jinclude.h.)
+
+
+C source code files:
+
+These files contain most of the functions intended to be called directly by
+an application program:
+
+jcapimin.c Application program interface: core routines for compression.
+jcapistd.c Application program interface: standard compression.
+jdapimin.c Application program interface: core routines for decompression.
+jdapistd.c Application program interface: standard decompression.
+jcomapi.c Application program interface routines common to compression
+ and decompression.
+jcparam.c Compression parameter setting helper routines.
+jctrans.c API and library routines for transcoding compression.
+jdtrans.c API and library routines for transcoding decompression.
+
+Compression side of the library:
+
+jcinit.c Initialization: determines which other modules to use.
+jcmaster.c Master control: setup and inter-pass sequencing logic.
+jcmainct.c Main buffer controller (preprocessor => JPEG compressor).
+jcprepct.c Preprocessor buffer controller.
+jccoefct.c Buffer controller for DCT coefficient buffer.
+jccolor.c Color space conversion.
+jcsample.c Downsampling.
+jcdctmgr.c DCT manager (DCT implementation selection & control).
+jfdctint.c Forward DCT using slow-but-accurate integer method.
+jfdctfst.c Forward DCT using faster, less accurate integer method.
+jfdctflt.c Forward DCT using floating-point arithmetic.
+jchuff.c Huffman entropy coding for sequential JPEG.
+jcphuff.c Huffman entropy coding for progressive JPEG.
+jcmarker.c JPEG marker writing.
+jdatadst.c Data destination manager for stdio output.
+
+Decompression side of the library:
+
+jdmaster.c Master control: determines which other modules to use.
+jdinput.c Input controller: controls input processing modules.
+jdmainct.c Main buffer controller (JPEG decompressor => postprocessor).
+jdcoefct.c Buffer controller for DCT coefficient buffer.
+jdpostct.c Postprocessor buffer controller.
+jdmarker.c JPEG marker reading.
+jdhuff.c Huffman entropy decoding for sequential JPEG.
+jdphuff.c Huffman entropy decoding for progressive JPEG.
+jddctmgr.c IDCT manager (IDCT implementation selection & control).
+jidctint.c Inverse DCT using slow-but-accurate integer method.
+jidctfst.c Inverse DCT using faster, less accurate integer method.
+jidctflt.c Inverse DCT using floating-point arithmetic.
+jidctred.c Inverse DCTs with reduced-size outputs.
+jdsample.c Upsampling.
+jdcolor.c Color space conversion.
+jdmerge.c Merged upsampling/color conversion (faster, lower quality).
+jquant1.c One-pass color quantization using a fixed-spacing colormap.
+jquant2.c Two-pass color quantization using a custom-generated colormap.
+ Also handles one-pass quantization to an externally given map.
+jdatasrc.c Data source manager for stdio input.
+
+Support files for both compression and decompression:
+
+jerror.c Standard error handling routines (application replaceable).
+jmemmgr.c System-independent (more or less) memory management code.
+jutils.c Miscellaneous utility routines.
+
+jmemmgr.c relies on a system-dependent memory management module. The IJG
+distribution includes the following implementations of the system-dependent
+module:
+
+jmemnobs.c "No backing store": assumes adequate virtual memory exists.
+jmemansi.c Makes temporary files with ANSI-standard routine tmpfile().
+jmemname.c Makes temporary files with program-generated file names.
+jmemdos.c Custom implementation for MS-DOS (16-bit environment only):
+ can use extended and expanded memory as well as temp files.
+jmemmac.c Custom implementation for Apple Macintosh.
+
+Exactly one of the system-dependent modules should be configured into an
+installed JPEG library (see install.doc for hints about which one to use).
+On unusual systems you may find it worthwhile to make a special
+system-dependent memory manager.
+
+
+Non-C source code files:
+
+jmemdosa.asm 80x86 assembly code support for jmemdos.c; used only in
+ MS-DOS-specific configurations of the JPEG library.
+
+
+CJPEG/DJPEG/JPEGTRAN
+====================
+
+Include files:
+
+cdjpeg.h Declarations shared by cjpeg/djpeg/jpegtran modules.
+cderror.h Additional error and trace message codes for cjpeg et al.
+transupp.h Declarations for jpegtran support routines in transupp.c.
+
+C source code files:
+
+cjpeg.c Main program for cjpeg.
+djpeg.c Main program for djpeg.
+jpegtran.c Main program for jpegtran.
+cdjpeg.c Utility routines used by all three programs.
+rdcolmap.c Code to read a colormap file for djpeg's "-map" switch.
+rdswitch.c Code to process some of cjpeg's more complex switches.
+ Also used by jpegtran.
+transupp.c Support code for jpegtran: lossless image manipulations.
+
+Image file reader modules for cjpeg:
+
+rdbmp.c BMP file input.
+rdgif.c GIF file input (now just a stub).
+rdppm.c PPM/PGM file input.
+rdrle.c Utah RLE file input.
+rdtarga.c Targa file input.
+
+Image file writer modules for djpeg:
+
+wrbmp.c BMP file output.
+wrgif.c GIF file output (a mere shadow of its former self).
+wrppm.c PPM/PGM file output.
+wrrle.c Utah RLE file output.
+wrtarga.c Targa file output.

+
+RDJPGCOM/WRJPGCOM
+=================
+
+C source code files:
+
+rdjpgcom.c Stand-alone rdjpgcom application.
+wrjpgcom.c Stand-alone wrjpgcom application.
+
+These programs do not depend on the IJG library. They do use
+jconfig.h and jinclude.h, only to improve portability.
