MarsSeed [1] filed a deletion request for ccwatcher [2]: Broken package from 2015 for chemistry toolkit Avogadro1, discontinued 2 years ago (successor project is a major rewrite called Avogadro2).
This package unintendedly mixes Python2 and Python3 bingings for Qt4. But it seems no one uses this package. I recommend deletion. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/ccwatcher/
