# Experimental top-level setup.py for rpki CA tools.
# 
# This is not yet ready for prime time.
#
# General idea here is that we can use this with Python-aware platform
# packaging systems, and our code here deals with the strange build
# environment required when the system copy of OpenSSL isn't usable.
#
# So yes, you are seeing a setup.py which calls autoconf and make.
# Strange, but so long as it works as Python expects, good enough.
