Our tlgtk is built for Python 2, which is no longer available on modern distros. We need to convert tlgtk to Python 3. Also see bug 7508 for using PyGObject/Gtk3 in tlgtk.
It's easier to find PyGObject for Python 2 than it is to find Pygtk2 for Python 3 (has that ever existed?), so that will dictate the order we do things.
`tlgtk` has now been converted to python 3. No significant changes had to be done for this change since we did all the heavy lifting when migrating from PyGTK to PyGObject (see bug 7508). Marking as resolved.
The changes looks good, closing.
