Been trying this out for a few hours while on the train back from
Edinburgh (Linuxcon Europe), without success.  Kind of suspecting
I'll need to learn pdb soon. :(

It's kind of weird, as I'm pretty sure I *used* to have this working
with an older version of PyCharm (2.7.x).  The new 3.0 version of
PyCharm is just giving me SEGFAULT and SIGABRT when I try to get a
Gluster translator working with it (frustrating).

/me will keep trying different things for a bit

Yeah, that's why I was thinking it was libgfapi stuff getting pulled in
not Swift.  The import line in your pdf needs updating btw, as the
import line for current git head needs to be:

  from gluster import gfapi

That would make the import line:

  from gluster import glupy

Wouldn't it?  No objections to that, it's fairly simple and pretty logical. :)
