# Python makefile for the eclipse-python module
# N. Devillard - April 2001
# R. Rengelink - Jan 2002 (rewrite for distutils)
# The following script will attempt to compile all eclipse library
# sources into a single shared library in ./lib
# It piggybacks on the eclipse main C library for compiler definitions,
# to avoid having several sources of compiler settings.
# In the future, this hack should be replaced by a call to Distutils,
# once I understand how it is supposed to work and if it can do this
# at all :-)
