[Distutils] setuptools: Spelling < 3.1.0beta3 ?

[Pete]

Hi-

What's the proper way to spell "any version in the 3.0.x series" if a  
project has a 3.1.0beta3 release?

Specifically, CherryPy has both 3.0.2 and 3.1.0beta3 releases.  I'd  
like to depend on any 3.0.x

I've tried both 'CherryPy < 3.1' and 'CherryPy < 3.1.0' in my  
install_requires, and both cause setuptools to pull 3.1.0beta3.

I realize I can use 'CherryPy == 3.0.2' but that defeats the "any  
3.0.x" idea...
