I've seen twenty threads on this and I still don't know/recall
whether there's a clear answer. :-(

Actually, it's all you've got to work with.  On Linux and Windows,
at least, it's got either just the script name, if you're running
from the current directory, or a path (relative or absolute) to
the directory where the script is run from.  It's like this whether
py2exe'd or not, too.

__file__ could be of assistance, but it doesn't exist when
you've py2exe the thing...

Yeah, sys.path isn't much good for this sort of thing.
