| 4 | NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx | |
| 5 | driver and thus may have bugs that are not present in the original version. | |
| 6 | Please send bug reports and support requests to <luc@saillard.org>. | |
| 7 | The decompression routines have been implemented by reverse-engineering the | |
| 8 | Nemosoft binary pwcx module. Caveat emptor. | |
