How can I pass parameters to a RequestHandler?

The Python documentation includes an example of creating an HTTP server:

def run(server_class=HTTPServer, handler_class=BaseHTTPRequestHandler):    server_address = ('', 8000)    httpd = server_class(server_address, handler_class)    httpd.serve_forever()

A RequestHandler class is provided to the Server, which then takes care of instantiating the handler automatically.

Let's say I want to pass in custom parameters to the request handler when it's created. How can and should I do that?

More specifically, I want to pass in parameters from the command line, and having to access sys.argv inside the request handler class seems unnecessarily clunky.

It seems like this should be possible by overriding parts of the Server class, but I feel like I'm overlooking a simpler and better solution.
