#
# This is a plugun from streamtuner1. It has been rewritten for the
# more mundane plugin API of streamtuner2 - reimplementing ST seemed
# to much work.
# Also it has been rewritten to query DMOZ directly. Google required
# the use of fake User-Agents for access, and the structure on DMOZ
# is simpler (even if less HTML-compliant). DMOZ probably is kept
# more up-to-date as well.
# PS: we need to check out //musicmoz.org/
