To download the first 1999 release of the free/open source package, users have to accept the licence agreement and fill a registration form on the PARAPET (lien brisé) web site. This was suspended (lien brisé) after the end of the project.
For the more recent releases (some bugs fixed) and other options added, including simulation of transmission scanning, please contact Frédéric Schoenahl or Dr Habib Zaidi.
