5 | NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx | ||
6 | driver and thus may have bugs that are not present in the original version. | ||
7 | Please send bug reports and support requests to <luc@saillard.org>. | ||
8 | The decompression routines have been implemented by reverse-engineering the | ||
9 | Nemosoft binary pwcx module. Caveat emptor. | ||
