#
# Xiph.org maintains the Ogg streaming standard and Vorbis
# audio compression format, amongst others.  The ICEcast
# server is an 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.

# Xiph via I-O
#
#
# Xiph meanwhile provides a JSOL dump, which is faster to download and process.
# So we'll use that over the older yp.xml. (Sadly it also doesn't output
# homepage URLs, listeners, etc.)
#
# Xiphs JSON is a horrible mysqldump concatenation, not parseable. Thus it's
# refurbished on //api.include-once.org/xiph/cache.php for consumption. Which
# also provides compressed HTTP transfers and category slicing.
#
# Xiph won't be updating the directory for another while. The original feature
# request is now further delayed as summer of code project:
# ยท https://trac.xiph.org/ticket/1958
# ยท https://wiki.xiph.org/Summer_of_Code_2015#Stream_directory_API
