[antlr-interest] generating multiple files from a single input file

[Tom Smith]

Gavin, thanks for the idea.

In addition to Gavin's suggestion, I guess it is possible to have a single tree
walker that uses different StringTemplate groups to form the output.  Does
anyone have thoughts on the workability of these approaches?

Thanks,
Tom.
