#
# Adds a context menu "Add in RadioTray.." for bookmarking.
# Should work with old Radiotray and Radiotray-NG. It will
# now probe for RTNG first and prefers to edit its bookmark
# list.
#
# The mapping options:
#   · "root" is just meant for the old Radiotray format.
#   · "group" tries to fit genres onto existing submenus.
#   · "category" maps just the channel category.
#   · "channel" instead creates `Shoutcast - Rock` entries.
#   · "asis" will transfer the literal station genre.
#   · "play" is unused.
#
# With the old Radiotry this plugin will fall back to just
# playUrl() until the addRadio remote call is added.
# The patch for radiotray/DbusFacade.py would be:
#   +
#   +    @dbus.service.method('net.sourceforge.radiotray')
#   +    def addRadio(self, title, url, group="root"):
#   +        self.dataProvider.addRadio(title, url, group)
