# Initial mk for building and installing python wheels

# Variables:
# 
# WHEELFILE:		path to the wheelfile to be installed
#			only needs to be set if do-build is redefined
#
# MASTER_SITE_WHEEL:	master site to grab wheels directly 
#			use like ${MASTER_SITE_WHEEL:=project/}
#			uses debian pypi redirector so that there
#			is no need for hashes in urls.

# TODO: 		fix BUILDDIR support
