The greater the return value, the more preferred it is. If not finding wheels, then sorted by version only. If finding wheels, then the sort order is by version, then: 1. existing installs 2. wheels ordered via Wheel.support_index_min() 3. source archives Note: it was considered to embed this logic into the Link comparison operators, but then different sdist links with the same version, would have to be considered equal � zB%s is not a supported wheel for this platform.
