Yes, it would be very interesting to see! Is it 
"backwards-compatible" (or whatever you call it) with real Java?

BTW, I'm working on Linux (using Mono .NET) so Visual Studio 
project files aren't so useful for me.

I'm no .NET expert, but if I understand correctly the C# source
code would be perfectly valid to call from VB.NET, right? Did
you do this just to be able to have a 100% VB source code project?
Or are there some other advantages?

Anyway, I guess it would always be interesting to add more 
languages to the output layer.

It would be fantastic if you managed to fix this. Last I 
looked at it, I didn't get any brilliant ideas, so it seemed
a bit cumbersome to implement. And that was only for string
(i.e. "blahblah") tokens. For regexp tokens (i.e. <<blahblah>>)
this will be even trickier to fix... (So don't be discouraged
if you run into problems!)

Anyway the regexp part of the tokenizer is pending a complete
rewrite to generate a DFA instead of using the current 
structure. A DFA might be tricky to generate but should speed
up the tokenizer quite a bit once working correctly... But I've
been working 100% on another project for some time now, so I've
had little time for Grammatica the last six months or so. And
things doesn't look so bright ahead either, so everyone please
accept my apologies if I'm slow on answering mails and releasing
new versions.

Cheers,
