Returns the version of the product as (description, [major,minor,micro,beta]).
If the release is official, `beta` will be 9999 (OFFICIAL_BUILD).
1. If in a git repository, use the latest tag (git describe).
2. If in an unzipped source directory (from sdist),
read the version from the PKG-INFO file.
3. Use and complain a lot.
# My goal is to (1) provide accurate tags for official releases but (2) not have to manage tags for every test
# release.
# Official versions are tagged using 3 numbers: major, minor, micro. A build of a tagged version should produce
# the version using just these pieces, such as 2.1.4.
# Unofficial versions are "working towards" the next version. So the next unofficial build after 2.1.4 would be a
# beta for 2.1.5. Using 'git describe' we can find out how many changes have been made after 2.1.4 and we'll use
# this count as the beta id (beta1, beta2, etc.)
# Since the 4 numbers are put into the Windows DLL, we want to make sure the beta versions sort *before* the
# official, so we set the official build number to 9999, but we don't show it.
