As the old saying goes, Python is the only language with more Web frameworks than 
keywords. This is sometimes an advantage, but more often than not, it is an issue. 
In order to improve the interoperability between different frameworks, Phillip 
J. Eby proposed in 2003 a specification, the WSGI or Web Server Gateway 
Interface, a.k.a Whiskey. In my talk I will discuss how you can achieve portability
of your application by following the WSGI protocol. I will give practical
examples of how to use the WSGI reference implementation which is part of the
standard library (wsgiref), of how to supplement it with other WSGI-compliant 
libraries (notably Paste by Ian Bicking) and of how to integrate your WSGI 
application in different frameworks including Zope, Twisted, TurboGears et al. 
The talk is intended as a tutorial and requires only elementary knowledge of 
Web programming, at the level of simple CGI.
