# extraction-method: xml, regex, json
#
# Xiph.org maintains the Ogg streaming standard and Vorbis,
# Opus, FLAC audio, and Theora video compression formats.
# The ICEcast server is an open alternative to SHOUTcast.
#
# It also provides a directory listing of known internet
# radio stations; only a handful of them using Ogg though.
# The category list is hardwired in this plugin. And there
# are three station fetching modes now:
#
# → "JSON cache" retrieves a refurbished JSON station list,
# both sliceable genres and searchable.
#
# → "Clunky XML" fetches the olden YP.XML, which is really
# slow, then slices out genres. No search.
#
# → While the secret "buffy" mode keeps the XML blob in memory.
#
# → "Forbidden Fruits" extracts from dir.xiph.org HTML pages,
# with homepages and listener/max infos available. Also
# enables live server searching.
#
# The previous bitrate filter is now a separate plugin, but
# available for all channels.
