I started moving to AUR 4, updating packages, and synching back with AUR 3 a few days ago. I am doing job hunting, so these slipped down my priority list. However, I no longer use the unittest2 packages, so I approve of having maintainership transferred. I have orphaned the packages on AUR 3 and 4.

This is actually an orphan and merge request.

python{,2}-unittest2 has been flagged out of date in AUR3 since
2015-02-05.  The maintainer is unresponsive to email.  I would like to
maintain them in AUR4, and combine them into a split package.

Please merge the packages, and then orphan them.  I have a split
PKGBUILD ready to go that updates it to the latest upstream version.
