# Okay, while programming this, I missed the broadcast I wanted to hear. Again(!)
# But still this is a useful extension, as it allows recording and playing specific
# stations at a programmed time and interval. It accepts a natural language time
# string when registering a stream. (Via streams menu > extension > add timer)
#
# Programmed events are visible in "timer" under the "bookmarks" channel. Times
# are stored in the description field, and can thus be edited. However, after editing
# times manually, streamtuner2 must be restarted for the changes to take effect.
