[antlr-interest] ANTLR itself written using treewalkers?

Whew! Too much of a good thing :)

Trying to grok the overall structure of ANTLR itself...my first question...

ANTLR2 itself doesn't seem to use a treewalker. Why not?

And is there any sort of description of the internal design of ANTLR 
itself,
or do I need to just start at Tool.java and drill down?
