The tool you're looking for is Semantic, not Senator. It contains a
simple LL parser called "Bovine" and a more advanced LALR parser which
is pretty much a port of Bison to Emacs Lisp, called "Wisent". If you
get the latest Emacs 24.4 you should find the documentation for them in
the accompanied info files (do 'C-h i'). If you want to get an
impression of the AST that is produced, load a simple C file, do 'M-x
semantic' and then 'M-x bovinate'. For further questions, the best place
to ask is the CEDET mailing list
http://sourceforge.net/p/cedet/mailman/
(also available on Gmane as gmane.emacs.cedet).
