I haven't built one, but I'm hoping to have time to use my new output 
grammar stuff to generate java back out.  Basically I have these string 
templates that are really documents that have attributes ("holes") that 
you can fill in with values via code.  You can also reference other 
documents thus providing a recursive grammatical spec sort of thing.  
The only thing I have not quite figured out is how to "correctly" get 
AST data pushed into the correct attributes of the output grammar.  If 
anybody wants to try futzing around, I will send them my string template 
prototype.  The StringTemplate class is what pushes out jGuru website.  
The DB fills in the attributes and then I just toString() the document 
and voila: you have an output page :)
