"""
SCGI-->WSGI application proxy, "SWAP".

(Originally written by Titus Brown.)

This lets an SCGI front-end like mod_scgi be used to execute WSGI
application objects.  To use it, subclass the SWAP class like so::

class TestAppHandler(swap.SWAP):
       def __init__(self, *args, **kwargs):
           self.prefix = '/canal'
           self.app_obj = TestAppClass
           swap.SWAP.__init__(self, *args, **kwargs)

where 'TestAppClass' is the application object from WSGI and '/canal'
is the prefix for what is served by the SCGI Web-server-side process.

Then execute the SCGI handler "as usual" by doing something like this::

scgi_server.SCGIServer(TestAppHandler, port=4000).serve()

and point mod_scgi (or whatever your SCGI front end is) at port 4000.

Kudos to the WSGI folk for writing a nice PEP & the Quixote folk for
writing a nice extensible SCGI server for Python!
