Hello glueviz maintainers,

I was just looking at a different bug and saw this.  The source is the
hand-written script debian/glue (installed by
debian/glueviz.install).  This is an old generated script which
imports pkg_resources instead of using the current import mechanism.
It also has an out-of-date __requires__.

I would suggest removing this in favour of patching setup.cfg to add
an appropriate entry to options.entry_points, presumably something
like:

gui_scripts =
    glue = glue:glue

(but I have no idea what the correct incantation should be: I can't
fathom where the entry point currently is).

Then in debian/rules, patch the resulting file to add the QT_API
setting.

Best wishes,

   Julian
