# Name: thewb.py
# Python Script
# Author: R.D. Vaughan
# Purpose:
#   This python script is intended to perform The WB video lookups for the MythTV Netvision plugin
#   based on information found on the http://www.thewb.com/ website. It
#   follows the MythTV Netvision grabber standards.
#
# Command example:
# See help (-u and -h) options
#
# Design:
#   1) Read the ".../emml/feConfig.xml"
#   2) Check if the CGI Web server should be used or if the script is run locally
#   3) Initialize the correct target functions for processing (local or remote)
#   4) Process the search or treeview request and display to stdout
