 Various components for mesecons and digilines.
 
-
-
-Dropper
--------
-* This block is only available if digilines and/or mesecons are loaded.
-
-Contains an inventory and drops an item on command. Also acts as a
-digilines conductor. If the hopper mod is loaded, will take items from the
-top and sides, and release them from the bottom.
-
-UI
-
-Channel - digilines channel of dropper.
-Top 16 slot inventory - storage of items to drop.
-Bottom 32 slot inventory - player's inventory.
-
-Mesecons
-	Drops the next item when power is turned on.
-
-Digilines messages
-
-"drop"
-	Drops the next item. No drop if dropper is empty.
-
-"drop <slot>"
-	Drops 1 item from the given slot (1 to 16). No drop if slot is empty.
-	eg. "drop 7"
-
-"drop <itemname>"
-	Drops 1 item of the given name. No drop if dropper does not contain the
-	item.
-	eg. "drop default:stone"
-
-When an item is dropped a digilines message is sent with the dropper's
-channel. The message is a table with the following keys:
-{
-	action = "drop",
-	name = "<itemname>", -- name of dropped item
-	slot = <slot> -- slot number the item was taken from (1 to 16).
-}
-
-
-
-Dispenser
----------
-* This block is only available if digilines and/or mesecons are loaded.
-
-Contains an inventory and dispenses (with velocity) an item on command.
-Also acts as a digilines conductor. If the hopper mod is loaded, will take
-items from the top and sides, and release them from the bottom.
-
-Dispensers support mobs mod if loaded and Spawn mobs setting is enabled.
-Will spawn the entity from an 'egg' if possible, or the 'egg' is dispensed.
-If a chicken egg is dispensed a 10% chance a chicken is dispensed instead.
-If the spawned entity can be owned (or tamed) and the dispenser is owned
-the owner of the dispenser is set as the owner of the entity.
-
-UI

-"dispense <itemname>"
-	Dispenses 1 item of the given name. No dispense if dispenser does not
-	contain the item.
-	eg. "dispense default:stone"

-Player Button
--------------
-* This block is only available if both digilines and digistuff are loaded.
-
-When pressed sends a digilines message with the name of the player that
-pressed the button.
-
-The first time the button is right clicked a form opens to set the
-digilines channel. After that right click presses the button. The
-digilines cannot be changed after its set.
-
-When the button is pressed a digilines message is sent with the button's
-channel in the form:
-{
-	action = "player",
-	name = <player name>
-}
-
-
-
-DigiSwitch
-----------
-* This block is only available if both digilines and mesecons are loaded.
-
-Digiswitches act as both a digilines message target and a digilines cable,
-as well as a mesecons power source. They can be placed beside each other
-to form a bank, horizontally or vertically.
-
-Right click the digiswitch to give it a channel.
-
-Mesecon power can be delivered at 6 sides of the digiswitch, the adjacent
-4 in the (x, z), above and below. Around the connector on these sides are a
-colored border indicating the side. The sides are named "red", "green",
-"blue", "yellow", "white" and "black".
-
-The digilines message sent to the digiswitch dictates the action, "on" or
-"off". The action can be followed with the side to act upon, separated by
-a space. eg. "on white". If a side is stated only that side is acted upon.
-If the side is omitted (or is invalid) all 6 sides are acted upon. If the
-side name "switch" is give the power is supplied the same as a mesecons
-switch (all horizontal sides, one below, this height and one above).
-
-
-
-MoveFloor
----------
-* This block is only available if mesecons and mesecons_mvps is loaded.
-
-The MoveFloor block responds to a mesecons power source in the 4 horizontal
-directions. If the power source is one higher the MoveFloor moves up to
-that height. If the power source is one lower the MoveFloor moves down to
-that height. Powering an adjacent block has no effect. The power source
-should be turned off before another move or the MoveFloor will oscillate.
-
-Any horizontally adjoining MoveFloor acts as a single block (only one
-needs to be powered).
-
-The MoveFloor will move up to 3 blocks stacked on it.
-
-If using a DigiSwitch as the power source use the side name "switch" or
-the MoveFloor will not move.
-
-
-
-Solid Color Conductors
-----------------------
-* These blocks are only defined if mesecons and unifieddyes are loaded.
-
-Provides 2 blocks that can be colored the same as Solid Color Block (with
-the air brush) and is both a mesecons and digilines conductor.
-
-The Solid Color Conductor block conducts in the 'default' directions and
-the Solid Color Horizontal Conductor only conducts horizontally.
+*	Dropper, drops an item on command.
+*	Dispenser, dispenses (with velocity) an item on command.
+*	Collector, picks up dropped items in adjacent block, with optional filtering.
+*	Detector, detects items or entities within a given radius.
+*	Siren, plays a sound repeatedly while active.
+*	Puncher, punches players or entities within a given reach.
+*	Player button, sends digilines message with player name.
+*	Breaker, digs the node directly in front.
+*	Hologram, projects a hologram above the hologram node.
+*	Fan, blows any entity, player or drop in front of the fan.
+*	Digiswitch, digilines controlled mesecons power.
+*	Movefloor, similar to vertical mesecons movestone.
+*	Solid color conductor blocks, same as Solid Color Block but also mesecons and digilines conductor.
+
+See the docs folder for details on each item.
 
 
 
 The following are also defined as variants of the original mod item, if
 the relevant mod is loaded.
-+	lwcomponents:touchscreen - digistuff:touchscreen as full sized node.
-+	lwcomponents:panel - digistuff:panel as full sized node.
+*	Touchscreen, full node variant of digistuff:touchscreen.
+*	Panel, full node variant of digistuff:panel.
