It's not. It's a protocol for HTTP servers <-> Python web applications
interaction, and barely higher-level than CGI itself.

It's much more simple. The "request" is a CGI-environ like dict, the
"response" is made of a callable(http_code, *http_headers) plus an
iterable for the response's body. Here's the standard wsgi hello_world:

def hello_app(environ, start_response):
  start_response('200 OK', [('Content-type', 'text/plain')])
  return ['Hello WSGI World']


The WSGI spec is really dead-simple. It shouldn't take much more than 10
to 15 minutes to read and understand for anyone having some basic
knowledge about HTTP and web programming.
