Henry--
There will be an ANTLR 2.8e0 ("e" for "experimental" in preparation
for 3.0) release candidate out "soon". I have some more work to do,
particularly on documentation, but it will include
target-language-independent tree rewrite support and automated tree
grammar generation. My guess is that we can get a release candidate
out soon after 2.7.3 gets to final release--possibly early February.
Manually creating your own trees works, but it gets messy in large
grammars (I've been creating Python parse trees in an ANTLR tree
grammar, so I have some recent experience). I'd advise using ANTLR
tree generation rather than creating custom trees in actions.
