|

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.
