#
# A station list website featuring a map. (Uncovered via streamripper
# homepage, which however mentions those streams not being recordable).
# Most entries are AAC+. Else MP3. No Vorbis streams.
#
# Furthermore no homepages, and playing= field is only sometimes set.
# Gotostationpage URLs don't work either. The website seems a bit
# unmaintained. Yet still provides iPhone/Android apps.
#
# This plugin just fetches a single result list page per category. But
# supports the live server search, as the result format is identical
# and easy to extract.
