[Mac src] Hammer, a recursive descent parser framework

[Rob Rix]

http://github.com/robrix/hammer/

Hammer is a recursive descent parser framework written entirely in
Cocoa. You can build grammars as a tree of objects, or with a grammar
definition grammar similar to EBNF. Comments, requests, suggestions,
and patches are welcome!

Sincerely,
