OK - I have set that up, wheels building on the "daily" branch here:

https://travis-ci.org/MacPython/cython-wheels/branches

But, I'm a bit worried by the pre-release naming scheme, because the
built wheel has name of form "Cython-0.26.1a0-cp..." . Can I ask -
where does the "1a0" come from?  Can it be used to select the most
recent pre-release wheel?  I mean, if we build a wheel from a later
commit, will pip find the later wheel before this one?

Cheers,

Matthew
