 This adds some interesting items to the Digilines mod.
 
-## Multicolour Light block
-
-This block can be controlled and read via a digiline. The channel can only be configured once; to change it, the node must be dug and placed again. Anyone can set it, not just the placer. The channel will be a string, even when digits are entered. An empty channel name is not allowed.
-
-The digiline signal must be a string with one of these formats:
-
-- "on" - light on
-- "off" - light off
-- "#rgb" - change colour (3 hex digits)
-- "#rrggbb" - colour (6 hex digits)
-- "on#rgb"
-- "off#rgb"
-- "on#rrggbb"
-- "off#rrggbb" - change both light on/off status and colour
-
-Despite accepting any hex colours, due to Minetest limitations only 125 are possible, which are all possible combinations of values 00, 40, 80, C0 and FF in each of R, G and B (values 00-33 count as 00, values 34-66 count as 40, values 67-99 count as 80, values 9A-CC count as C0, and values CD-FF count as FF)
-
-After being configured, it will send on the selected channel the string "L <playername>" when the node is punched (L for left-clicked) and the string "R <playername>" when the node is right-clicked (with the actual player's name, of course).
