Not exactly true. Even in derived work, you have to obey the license conditions of the work you derive from. You may extend it further, but cannot change, or remove any requirements. Only the copyright holder can make changes. Example: If there is an "advertising clause" in the BSD-like license you derive from, you cannot restrict it to GPL, because GPL especially forbids inserting advertising clauses. There are a few more caveats, when you want just to take BSD-like licensed code and make it GPL. That's why there is GNU-TLS rewritten from scratch instead of taking BSD-like licensed OpenSSL and changing its license. That's why Linux TCP/IP stack was implemented from scratch instead of taking a very good one from *BSD and putting it into the Linux kernel while changing license. etc. -- Tomasz Sterna Xiaoka Grp. http://www.xiaoka.com/
