# Has only major categories. Does not provide channel homepages, and
# is a bit slow due to huge page sizes. No search function implemented

# · Provides around 20 categories, associated to numeric ids (?g= parameter)
#
# · Station lists are one <tr> block each, with a JS inline script associating
# some web player parameters.
#
# · Each station has a station id=, but also a stream_id= for the playlist
# generator.
#
# · Normally just provides a web player, but used to show .pls links for various
# players. Meanwhile this is hidden, but the playlist generator is still
# available - so doesn't require double lookups.
