3. Copyright

SSLtcl is copyrighted by Peter Antman, and licenced under GNU/GPL. This means that it is free fore use and further development but that any changes has to be made public.

SSLtcl does not contain code only written by me. In the spirit of free software development a have reused code, which means that SSLtcl contains code, codefragments or hard to decide inspired by other code This code is copyrighted under other conditions than GNU/GPL

SSLtcl contains codes from:

tcl8.0 core

All of this code are copyrighted under somewhat more liberal rules. That is. It is possible to make changes to the code and incorporate them in to a product without releasing the new source code. This is not possible under GNU/GPL - and that is its intention. To do this with SSLtcl you would have to remove all codes written by me, and that would eventually mean that SSLtcl would stop working.

That is. You are free to use and modify SSLtcl as long as my and all other copyright holders are not removed and as long as the sourcecode is made freely available.

In my interpretation this makes it possible to use the vanilla SSLtcl in a commercial product without being forced to release source code for that product, except for SSLtcl, which - if vanilla - already is freely available.
