SV = "PiKoleTo Live 1.00 Lua5"

-- by Mutor      ..Reworked an old script a bit 10/07/05

-- Alerts operators if trigger file is missing.
-- Now reads trigger table from external file.
-- Includes settable string (command) to list available triggers.

--Trigger table to be stored in external file
--Add / Remove triggers as you wish, follow the format.
