#
# Streamtuner2 is a GUI for browsing internet radio directories, music
# collections, and video services - grouped by genres or categories.
# It runs your preferred audio player, and streamripper for recording.
#
# It's an independent rewrite of streamtuner1. Being written in Python,
# can be more easily extended and fixed. The mix of JSON APIs, regex
# or PyQuery extraction makes list generation simpler and more robust.
#
# Primarily radio stations are displayed, some channels however are music
# collections. Commercial and sign-up services are not an objective.
