#
# SickGear Process Media extension for NZBGet
# ===========================================
#
# If NZBGet v17+ is installed on the same system as SickGear then as a local install,
#
# 1) Add the location of this extension to NZBGet Settings/PATHS/ScriptDir
#
# 2) Navigate to any named TV category at Settings/Categories, click "Choose" Category.Extensions then Apply SickGear-NG
#
# This is the best set up to automatically get script updates from SickGear
#
# #############
#
# NZBGet version 16 and earlier are no longer supported, please upgrade
#
# ############
#
# Notes:
# Debian doesn't have pip, _if_ requests is needed, try "apt install python-requests"
# -----
# Enjoy
