IIUC this is a theory that hasn't been > tested in court. Notice that what has been tested in court, is that a _translation_ is a derived work, and subject to the copyright of the original copyright holder. And this is something that I would love to see tested in court, if somebody took a GPL library written in, say lisp, translated it into say C, and tried to distribute it under a different licence. -- __Pascal Bourguignon__ http://www.informatimago.com/ “The factory of the future will have only two employees, a man and a dog.
