Specifies a range of python versions. So this would work for Python 2.7 but not 2.7.1? Or does 2.7 implicitly mean a range of all Python 2.7 versions? Yes. 2.7 would mean all 2.7 versions. As 2.7.1 is a 2.7 release.

I suggest that this follow the Python syntax for ranges, where the end is non-inclusive. So "2.5:2.7" would mean "greater than or equal to 2.5, and less than 2.7". Which suggests that "2.5:" could be equivalent to "2.5+", as well as allowing ":3" to mean "any version less than 3.0".
