| 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. |
