[antlr-interest] ANTLR (C++) pretty printer?

[Loring Craymer]

Bryan--

I decided to see how fast I could generate one using antlr 2.8 and the 2.7.6
antlr.g.  It took me about three hours to extract the antlr grammar sans
actions and debug a tree grammar by taking advantage of the antlr 2.8 tree
grammar generator.  I then spent about six hours adding in actions to do the
printing (I already had some grammar printing routines lying around).

There are still a few minor bugs to be fixed, and I haven't yet tested the
options (with or without actions, or exceptions, or options, and a few other
flags).  I'll do a little more cleanup tomorrow and then post the result to
antlr.org.
