+
+Tiers
+-----
+The tier is a string, currently `"LV"`, `"MV"` and `"HV"` are supported.
+
+Network
+-------
+The network is the cable with the connected machine nodes. Currently the
+switching station handles the network activity.
+
+Helper functions
+----------------
+* `technic.pretty_num(num)`
+	* Converts the number `num` to a human-readable string.
+	* Use this function when showing players power values.
+* `technic.swap_node(pos, nodename)`
+	* Same as `mintest.swap_node` but it only changes the nodename.
+	* It uses `minetest.get_node` before swapping to ensure the new nodename
+	  is not the same as the current one.
+* `technic.get_or_load_node(pos)`
+	* If the mapblock is loaded, it returns the node at pos,
+	  else it loads the chunk and returns `nil`.
+* `technic.set_RE_wear(itemstack, item_load, max_charge)`
+	* If the `wear_represents` field in the item's nodedef is
+	  `"technic_RE_charge"`, this function does nothing.
+* `technic.refill_RE_charge(itemstack)`
+	* This function fully recharges an RE chargeable item.
+	* If `technic.power_tools[itemstack:get_name()]` is `nil` (or `false`), this
+	  function does nothing, else that value is the maximum charge.
+	* The itemstack metadata is changed to contain the charge.
+* `technic.is_tier_cable(nodename, tier)`
+	* Tells whether the node `nodename` is the cable of the tier `tier`.
+* `technic.get_cable_tier(nodename)`
+	* Returns the tier of the cable `nodename` or `nil`.
+* `technic.trace_node_ray(pos, dir, range)`
+	* Returns an iteration function (usable in the for loop) to iterate over the
+	  node positions along the specified ray.
+	* The returned positions will not include the starting position `pos`.
+* `technic.trace_node_ray_fat(pos, dir, range)`
+	* Like `technic.trace_node_ray` but includes extra positions near the ray.
+	* The node ray functions are used for mining lasers.
+* `technic.config:get(name)`
+	* Some configuration function
+* `technic.tube_inject_item(pos, start_pos, velocity, item)`
+	* Same as `pipeworks.tube_inject_item`
+
+Registration functions
+----------------------
+* `technic.register_power_tool(itemname, max_charge)`
+	* Same as `technic.power_tools[itemname] = max_charge`
+	* This function makes the craftitem `itemname` chargeable.
+* `technic.register_machine(tier, nodename, machine_type)`
+	* Same as `technic.machines[tier][nodename] = machine_type`
+	* Currently this is requisite to make technic recognize your node.
+	* See also `Machine types`
+* `technic.register_tier(tier)`
+	* Same as `technic.machines[tier] = {}`
+	* See also `tiers`
+
+### Specific machines
+* `technic.register_solar_array(data)`
+	* data is a table
+
+Used itemdef fields
+-------------------
+* groups:
+	* `technic_<ltier> = 1` ltier is a tier in small letters; this group makes
+	  the node connect to the cable(s) of the right tier.
+	* `technic_machine = 1` Currently used for
+* `connect_sides`
+	* In addition to the default use (see lua_api.txt), this tells where the
+	  machine can be connected.
+#
+#
+* `technic_run(pos, node)`
+	* This function is currently used to update the node.
+	  Modders have to manually change the information about supply etc. in the
+	  node metadata.
+
+Machine types
+-------------
+There are currently following types:
+* `technic.receiver = "RE"` e.g. grinder
+* `technic.producer = "PR"` e.g. solar panel
+* `technic.producer_receiver = "PR_RE"` supply converter
+* `technic.battery  = "BA"` e.g. LV batbox
+
+Switching Station
+-----------------
+The switching station is the center of all power distribution on an electric
+network.
+
+The station collects power from sources (PR), distributes it to sinks (RE),
+and uses the excess/shortfall to charge and discharge batteries (BA).
+
+For now, all supply and demand values are expressed in kW.
+
+It works like this:
+ All PR,BA,RE nodes are indexed and tagged with the switching station.
+The tagging is a workaround to allow more stations to be built without allowing
+a cheat with duplicating power.
+ All the RE nodes are queried for their current EU demand. Those which are off
+would require no or a small standby EU demand, while those which are on would
+require more.
+If the total demand is less than the available power they are all updated with
+the demand number.
+If any surplus exists from the PR nodes the batteries will be charged evenly
+with this.
+If the total demand requires draw on the batteries they will be discharged
+evenly.
+
+If the total demand is more than the available power all RE nodes will be shut
+down. We have a brown-out situation.
+
+Hence for now all the power distribution logic resides in this single node.
+
+### Node meta usage
+Nodes connected to the network will have one or more of these parameters as meta
+data:
+	* `<LV|MV|HV>_EU_supply` : Exists for PR and BA node types.
+	This is the EU value supplied by the node. Output
+	* `<LV|MV|HV>_EU_demand` : Exists for RE and BA node types.
+	This is the EU value the node requires to run. Output
+	* `<LV|MV|HV>_EU_input`  : Exists for RE and BA node types.
+	This is the actual EU value the network can give the node. Input
+
+The reason the LV|MV|HV type is prepended to meta data is because some machine
+could require several supplies to work.
+This way the supplies are separated per network.

+	C = Concrete, B = Blast-resistant concrete, L = Lead,
+	W = water node, # = reactor core, | = HV cable
+
+The man-hole is optional (but necessary for refueling).
+
+For the reactor to operate and not melt down, it insists on the inner
+7x7x7 portion (from the core out to the blast-resistant concrete)
+being intact.  Intactness only depends on the number of nodes of the
+right type in each layer.  The water layer must have water in all but
+at most one node; the steel and blast-resistant concrete layers must
+have the right material in all but at most two nodes.  The permitted
+gaps are meant for the cable and man-hole, but can actually be anywhere
+and contain anything.  For the reactor to be useful, a cable must
+connect to the core, but it can go in any direction.
+
+The outer concrete layer of the standard structure is not required
+for the reactor to operate.  It is noted here because it used to
+be mandatory, and for historical reasons (that it predates the
+implementation of radiation) it needs to continue being adequate
+shielding of legacy reactors.  If it ever ceases to be adequate
+shielding for new reactors, legacy ones should be grandfathered.
+
+For legacy reasons, if the reactor has a stainless steel layer instead
+of a lead layer it will be converted to a lead layer.

--- SWITCHING STATION
--- The switching station is the center of all power distribution on an electric network.
---
--- The station collects power from sources (PR), distributes it to sinks (RE),
--- and uses the excess/shortfall to charge and discharge batteries (BA).
---
--- For now, all supply and demand values are expressed in kW.
---
--- It works like this:
---  All PR,BA,RE nodes are indexed and tagged with the switching station.
--- The tagging is to allow more stations to be built without allowing a cheat
--- with duplicating power.
---  All the RE nodes are queried for their current EU demand. Those which are off
--- would require no or a small standby EU demand, while those which are on would
--- require more.
--- If the total demand is less than the available power they are all updated with the
--- demand number.
--- If any surplus exists from the PR nodes the batteries will be charged evenly with this.
--- If the total demand requires draw on the batteries they will be discharged evenly.
---
--- If the total demand is more than the available power all RE nodes will be shut down.
--- We have a brown-out situation.
---
--- Hence all the power distribution logic resides in this single node.
---
---  Nodes connected to the network will have one or more of these parameters as meta data:
---   <LV|MV|HV>_EU_supply : Exists for PR and BA node types. This is the EU value supplied by the node. Output
---   <LV|MV|HV>_EU_demand : Exists for RE and BA node types. This is the EU value the node requires to run. Output
---   <LV|MV|HV>_EU_input  : Exists for RE and BA node types. This is the actual EU value the network can give the node. Input
---
---  The reason the LV|MV|HV type is prepended toe meta data is because some machine could require several supplies to work.
---  This way the supplies are separated per network.
