This is exyapps, a LL(1) parser generator.

It is derived from yapps ( http://theory.stanford.edu/~amitp/yapps/
) by Amit J. Patel <amitp@cs.stanford.edu>.  He is no longer
maintaining it, and there seem to be several forks out there, all
with varying version numbers.  This copy was derived from some
patches included with Debian by Matthias Urlichs <smurf@debian.org>

Since I want to make some of my own specific changes, I'm actually changing 
the name so this package can have a distinctive identity.  


Installing / using exyapps
--

	python setup.py install

	cd /your/project

	exyapps my_grammar.exy

For now, the package is compatible with yapps; Someday, I want to
make parsers run without the exyapps package installed.

What is here?
--

Makefile
yapps_grammar.g
	yapps_grammar.g is the source code for exyapps/grammar.py
	type "make" to re-generate it, then do an svn commit

doc
	looks like latex source for the documentation

examples
	duh

exyapps
	the exyapps package that gets installed

scripts
	"exyapps" command that compiles a parser into python code.

setup.py

test
	not actual tests, but apparently some interesting input to
	run through the parser for testing
