Usage

For these examples, assume that the mysite module exists and defines a class called MyDirectory which inherits from quixote.Directory.

Run as an http server on port 8080
- qxserver.py --standalone mysite.MyDirectory
Run as an scgi server on port 2974
- qxserver.py mysite.MyDirectory
Run as an http server on a specific IP and port
- qxserver.py --standalone --ip=192.100.10.5 --port=80 mysite.MyDirectory
Run as a scgi server on a specific IP and port
- qxserver.py --standalone --ip=127.0.0.1 --port=7777 mysite.MyDirectory

mysite.py

from quixote2 import Directory

class MyDirectory (Directory):
   _q_exports = ['']

   def _q_index (self):
      return "Hello World"
