Freeware/opensource SIS unpacker for Windows and Linux

I wrote a program which extracts files packed into SIS packages, without needing SDK or installation on the device.

http://jumpjack.altervista.org/UIQ-freeware.html

It  supports PSION/EPOC (ER5) , Series60 files , UIQ files... (actually I think it supports ANY kind of SIS file). Alo multilanguage and multioptions SIS files are supported.

It could be useful to look inside SIS package for different platforms to attempt programs porting (e.g., OPL or Java programs).
