- * Copyright (C) 1995-2011, Thomas G. Lane, Guido Vollbeding.
- * This file is part of the Independent JPEG Group's software.

- * This file contains a command-line user interface for JPEG transcoding.
- * It is very similar to cjpeg.c, and partly to djpeg.c, but provides
- * lossless transcoding between different JPEG file formats.  It also
- * provides some lossless and sort-of-lossless transformations of JPEG data.
