Interesting -- the 'versions.cfg' file is not actually present in the repo tag / release tarball at all (by design -- the version pins are inlined into 'bulidout.cfg' and echoed in 'requirements.txt'): https://github.com/zopefoundation/Zope/tree/2.13.23
It looks like the http://download.zope.org/Zope2/index/2.13.23/versions.cfg file is generated by 'zope.z2release' (which I used to generate the index directory). That tool needs updating to avoid generating the 'extends' bit, as well as a long-pending PR to use the JSON API on PyPI.
What the easiest way to use the sources and ztk from the repository without checking it all out? Charlie -- Charlie Clark Managing Director Clark Consulting & Research German Office Kronenstr. 27a Düsseldorf D- 40217 Tel: +49-211-600-3657 Mobile: +49-178-782-6226
