I started wondering if there aren't any legal implications when deriving the 
new Java parser from this grammar. Its license doesn't seem to be very 
friendly to usage in open source (shown further down in this email).

I'll ask the OSDL people if it's possible to use it anyhow, because after all 
I'm not copying anything but only transcribing the rules. On the other hand, 
you could easily call that copying or stealing intellectual property too.

So, maybe I should just derive from the ANTLR parser, which is also the 
current Java parser in KDevelop (only our version is at Java 1.3 or so, 
whereas there's already a 1.5 version).

What do you think? Any experiences?

Thanks,
