-- module debugChannel --
-- by SwissalpS --
-- shows whatever is sent over a modchannel
--[[ in your server-side-mod, you need to
	-- join channel
	oC = core.mod_channel_join('tmi_debugChannel')
	-- best also register for channel signals to
	-- make sure join was successful
	-- at minimum check that channel is write-able
	if oC:is_writeable() then oC:send_all('your max 65k long message') end
	-- keep in mind that messages are async and also tmi has a delay between updates.

-- well, in theory that is how it should work. Did not work
