Comment 1 for bug 1528829

Please note that pyexiv2 (the python2 version) has been deprecated for a few years, in favour of GExiv2 (https://wiki.gnome.org/Projects/gexiv2), as stated here: http://tilloy.net/dev/pyexiv2/.
It is unsupported and hasn’t seen active development in years.

I am not sure how much work is going into py3exiv2 besides porting the original code base to python3.
