[Zope-dev] Building a Zope Site from a Source Distribution

Could anyone point me to documentation or instructions on how to build Zope to a particular version of Python. My goal is to understand the process so that I can do this on the Win32, Linux RPM and Solaris distributions (make directives, etc...). My first attempt will be focused on the Win32 distribution. I have Borland's C++ compiler (the one that has been released to the public). I have looked at the Win32 source distribution and the build_extensions.py file makes reference to setup20 and setup15 files in the lib/python folder. They aren't there so I am a bit puzzled as to the purpose of this build script. Eric
