""" Decorator to turn a WSGI application into a repoze.bfg view
callable. This decorator differs from the ``wsgiapp2`` decorator
inasmuch as fixups of ``PATH_INFO`` and ``SCRIPT_NAME`` within the
WSGI environment *are not* performed before the application is
invoked.
E.g.::
@wsgiapp
def hello_world(environ, start_response):
body = 'Hello world'
start_response('200 OK', [ ('Content-Type', 'text/plain'),
('Content-Length', len(body)) ] )

Allows the following view declaration to be made::
<view
view=".views.hello_world"
name="hello_world.txt"
context="*"
/>
The wsgiapp decorator will convert the result of the WSGI
application to a Response and return it to repoze.bfg as if the
WSGI app were a repoze.bfg view.
