More Plumheads

Lately I have expanded the scope of PlumHeaded Parakeet. The current plan is to have a side-by-side comparison of differend parsing and transformation techniques. These techniques are:

PHC

Take XML output of phc, http://phpcompiler.org/, and transform it with XSLT.

ANTLR3

Write parser and treegrammar in ANTLR3, http://www.antlr.org/wiki/display/ANTLR3/, with Java backend

Partridge

Use the Parrot compiler tools for parsing and transformation

The transformation target is in all three PAST-pm, an abstract syntax tree that can be trasformed into Parrot bytecode.
