Great, thanks alot for making it open source. I have wanted such a tool for
a long time now. Hopefully I will get some time to look at it properly soon,
ie a week or so.


Since finding out that GCC C++ 3.4 and 4.x are recusive descent I have been
interested in putting together a recusive descent C++ parser with a tool,
but non with the power to deal with ambiguous grammars existed, until APG.


I look forward to trying it out,
