#
# Streema lists over 70000 radio stations. Requires a double lookup
# however, as stream addresses are embedded in the web player only.
# Channel only polls one page of results, skips external stream pages.
#
# Currently playing field is quite spotty. No homepages are listed.
# The category map is prepared here, because it's quite slow to
# update. Region/city categories are left unused.
#
# The server search function is implemented however.
