needed for devel/py-b2 2.0.0
Please list yourself in the MAINTAINER filed. Thanks!
Update COMMENT to match setup.py:description (modulo portlint compliance):
"Factory+Registry pattern for Python classes"
This should probably be called py-class-registry2 as there are 2.x  and a 3.x  branches from the same project  but it's incompatible with at least B2 , which is the initial use case.
Also note the 3.x branch dropped 2.7 support.
Would you want to be a maintainer of this port? I'm happy to commit it to get the b2 port over the line, but you need to take on maintainership of this submission or find a maintainer for it.
