little language framework 0.4

[John Aycock]

The latest version of a framework for implementing little languages,
in 100% pure Python.  New features:

	-  A class which automagically constructs either parse
		trees or abstract syntax trees (ASTs) with minimal
		effort.
	-  A class for tree pattern matching, good for sophisticated
		code generation or interpreter implementation.

Old features:

	-  A generic scanner class.
	-  A generic parser class, which parses any context-free grammar.
	-  A class for traversing ASTs, useful in semantic checking and
		code generation.

Mixing and matching various components is possible; you're not locked into
using the whole thing if you don't want to.
