Thanks - after trying a few more things along the lines of your
suggestion, I think I see how it works.

If sys.path is '/home/me/lib/python2.0', then "import Physics"
doesn't work, but "import Scientific.Physics" does.

If sys.path is '/home/me/lib/python2.0/Scientific', then
"import Physics" works.
