This is the default behaviour of Publisher. Modules are *not* 
publishable objects, only certain types of objects within them may be 

Objects that are published:


  hello = "Hello, Bruce!"

Lists and tuples:

  order = ['spam', 'spam', 'spam', 'spam', 'eggs', 'spam']


  color = {'Lance': 'blue', 'Galahad': 'yellow', 'Robin': None}

Instances (publishable attributes & methods):

  instance = MyClass

Functions (only the output):

  def hello(req):
      return "Hello, Bruce!"

Objects that are not published:

Objects named with leading underscore:

  _secret = "BIGsecret"


  class MyClass:
      def __init__(self):
         self.attribute = "I can be published when I'm an instance."
      def function(self):
          return "Ocarina"

Objects within a function:

  def hello(req):
      name = "Michael Baldwin"
      return "Hello, Bruce!"

Imported modules and their objects (put the data into a publishable 
object first):

  import os

The module itself:


This list is not exhaustive, I'm sure I've missed some objects. 
Publisher will produce a variety of errors or unusable output, depending 
on the object. Unfortunately, one of these is the somewhat misleading 
"not found" error when attempting to access the published module itself.

Note that you generally do not need to import apache or use req.write in 
you Publisher modules. Simply return a string:

import calendar
def getMonth(req,month):
     return calendar.month(2006,int(month),2,3)
