-/* Linux driver for Philips webcam
- Decompression for chipset version 2 et 3
- (C) 2004 Luc Saillard (luc@saillard.org)
-
- NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx
- driver and thus may have bugs that are not present in the original version.
- Please send bug reports and support requests to <luc@saillard.org>.
- The decompression routines have been implemented by reverse-engineering the
- Nemosoft binary pwcx module. Caveat emptor.
