#
# Shoutcast is a server software for audio streaming. It automatically spools
# station information on shoutcast.com, which this plugin can read out. But
# since the website format is often changing, we now use PyQuery HTML parsing
# in favour of regular expression (which still work, are faster, but not as
# reliable).
#
# This was previously a built-in channel plugin. It just recently was converted
# from a glade predefined GenericChannel into a ChannelPlugin.
#
#
# NOTES
#
# Just found out what Tunapie uses:
# http://www.shoutcast.com/sbin/newxml.phtml?genre=Top500
# It's a simpler list format, no need to parse HTML. However, it also lacks
# homepage links. But maybe useful as alternate fallback...
# Also:
# http://www.shoutcast.com/sbin/newtvlister.phtml?alltv=1
# http://www.shoutcast.com/sbin/newxml.phtml?search=

# After its recent aquisition the layout got slimmed down considerably. So
