Raw Normal View History

"""An implementation of the Zephyr Abstract Syntax Definition Language.
See http://asdl.sourceforge.net/ and
http://www.cs.princeton.edu/research/techreps/TR-554-97
Only supports top level module decl, not view. I'm guessing that view
is intended to support the browser and I'm not interested in the
browser.
Changes for Python: Add support for module versions
