 Version specifiers for a given project are internally sorted into ascending

 Adjacent redundant conditions are also consolidated (e.g. ``">1, >2"`` becomes

 the ranges they fall within.  A project's version is then checked for
 membership in the resulting ranges. (Note that providing conflicting conditions
 for the same version (e.g. "<2,>=2" or "==2,!=2") is meaningless and may
