I think most people would agree that installation is whatever you need
to do between downloading the software and being able to use it. For
GNU packages, it's './configure && make && make install'. For Python
packages, it's usually './ install'.

The only way to get your packages on the PYTHONPATH currently is to:
   * install the packages to site-packages  (I don't have access)
   * edit the PYTHONPATH all users' environment  (again, no access)
   * create some boilerplate that edits sys.path at runtime (various
problems in previous post)
   * put your scripts directly above the package (this seems best so
far, but forces a flat hierarchy of scripts)
