Can you please point me to where I can find an in-depth discussion of return
value policies?
Are the 6 models under boost::python docs' ConverterGenerator all I can
use/need?

Lol, sorry about that. The secret police here at where I work restrict us
from doing *very dangerous* stuff like downloading MP3's, zip files with
source code in them, installing winamp... Ohh and also posting to
newsgroups. I have to use a different 'dirty' workstation to post here so I
can't simply copy/paste.
I'll make an effort to be more accurate in the future.

Cheers,
