[chimerax-users] Access ChimeraX GitHub repository

[Greg Couch]

The ChimeraX Toolshed uses the pypi protocols for package naming and 
metadata.  If the binary works for both Python 3.7 and 3.8, you might be 
able to get away with renaming it to 
ChimeraX_RMF-0.9-cp37-cp37m-cp38-macosx_10_13_x86_64.whl.  You should 
also be able to have separate bundles for Python 3.7 and 3.8.  It if 
doesn't work, it's a bug :-)   I'll create a ticket for adding support 
for the Python 3 Stable API (Py_LIMITED_API) to bundle_info.xml which 
will create binaries compatible with all versions of Python 3.

Of course, the Toolshed bundles should only be for production releases.  
The API of the daily builds has not been finalized, so bundles built 
against it might break tomorrow.

The Toolshed searching not finding rmf is a bug.  Will create a ticket 
for that.
