// This program requires either the libjpeg.a library or an internal DD

// The "official" archive site for this software is ftp.uu.net (Internet

// found there in directory graphics/jpeg. This particular version will
|
||||
// be archived as graphics/jpeg/jpegsrc.v6a.tar.gz.
|
||||
//
|
||||
// The makefile assummes you decompressed and build these in a directory
|
||||
// called "jpeg-6a" in the same location as the "FL" directory.
