Now that I'm learning JBurg, in their news;

*JBurg in ASC 2.0 and Apache Falcon*

Adobe's ASC 2.0 compiler (and its cousins Apache Falcon and FalconJS)  
use JBurg to generate their code generator. This two year long effort  
has given rise to a number of improvements in JBurg, especially  
"programming in the large" constructs such as shared pattern  
libraries, and greatly improved compile-time speed in the generated  
pattern matchers.

Many thanks to Adobe for their vision and support for this effort!

I'll say it again, its funny when you realize a path. There is to much  
time invested in the generator framework not to use it. It just has to  
be understood and tidied up. See if there are any abstractions that  
allow us to alter code generation based on compiler flags and various  
other run-time variables.

One thing I am learning is ANTLR and JBurg are a natural fit. It seems  
like ANTLR is now required with some of antlrs string template engine
