#
# Streamtuner2 is a GUI browser for internet radio directories. Various
# providers can be added, and streaming stations are usually grouped into
# music genres or categories. It starts external audio players for stream
# playing, and defaults to streamripper for recording broadcasts.
#
# 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 the target purpose.
