""" Nested dictionaries
This module implements the NestedDict class, which is a simple
tool to make it simpler to deal with nested dictionaries.
Here is a simple example showing how to use it::
dict=NestedDict()
dict["sql/username"]="guest"
dict["sql/password"]="secret"
print "Username: " + dict["sql"]["username"]
print "Password: " + dict["sql/password"]
"""
import types, UserDict
class NestedDict(UserDict.UserDict):
"""Nested dictionary class
@ivar seperator: seperator string
@type seperator: string
"""
