RFC: versioning proposal Re: [Zope3-dev] Specifying upper limits in dependencies

[Jim Fulton]

Hm, you're right.  Note:

 >>> from pkg_resources import *
 >>> parse_version('1.0') < parse_version('1.0-dev')
False
 >>> parse_version('1.0') < parse_version('1.0-r10')
True

So "dev" gets special treatment. Wonderful.  I guess that must be  
intuitive.
