# Name: bliptv.py
# Python Script
# Author: R.D. Vaughan
# Purpose:
#   This python script is intended to perform blip.tv lookups for the MythTV Netvision plugin
#   based on information found on the http://blip.tv/ website. It
#   follows the MythTV Netvision grabber standards.
#   This script uses the python module bliptv_api.py which should be included
#   with this script.
#   The bliptv.py module uses the full access API 2.0 api published by
#   http://blip.tv/ see: http://blip.tv/about/api/
#
# Command example:
# See help (-u and -h) options
#
# Design:
#   1) Import the specific target site API library.
#   2) Set the title for the scripts and the API key (optional) for the target video site
#   3) Call the common processing routine
