configSetup.py

#! This script updates the Injnos setup script to change the architecture and support for
#! OpenCl. It is meant to be used as part of the automatic build system to build all the
#! different variants of LuxRender that are supported:
#!   - 64-bit with OpenCL
#!   - 64-bit without OpenCL
#!   - 32-bit with OpenCL
#!   - 32-bit without OpenCL
#! Usage example:
#!   python configSetup.py --platform x64 --ocl luxSetup.iss
#!
