Yes, that's right.  Paths are UNIX style.  I can update this if it's
needed.  It's pretty low on the priority list for now.

I would rather not do that.  That'd be quite a lot more work to
maintain, and I am pretty sure it's not really required.  The end-users
of NGL (other developers, not end-users of NGL applications) should need
only NGL.framework and the PB template to create NGL applications.
That's my goal.

Ah, great!

The "pimpl" C++ idiom seems apropos.
