# Makefile for building Parsee
# ================================
# TODO: Consider making something akin to a configure script that checks 
# for dependencies, or maybe even use *autoconf* (the devil!)
#
# TODO: Either get rid of the GNU extensions, or use a script/program 
# to build Parsee on a POSIXly environment. I'd dig parsee-buildout, tbf.
