Not slightly, totally off-topic :-) Well, traffic is slow anyway...

Since the POV-Ray team itself claims it non open source, I will take their
word on it :-)
However, the claim is "While the POV-Ray&#8482; source code is freely
available, it isn't 'open' according to the currently popular definition of the
term (meaning that it isn't available to create derivative works other than
fully functional versions of POV-Ray)."

The key is "according to the currently popular definition of the term".

My definition of the term is rather "the source is available and you can
recompile it and even patch it". They actually welcome patches as they can be
integrated in the next version.

Same for free, the English is so ambiguous about it that it is usually
followed by the sentence "Free as in Free Speech not Free as in Free Beer". In
French, we use "libre" and "gratuit".
Well, I use the term as in "free beer", ie. it won't cost a cent.
