-Alloying iron with carbon is of huge importance, but in some processes
-the alloying is an implicit side effect rather than the product of
-explicit mixing, so it is a complex area.  In the real world, there is
-a huge variety of kinds of iron and steel, differing in the proportion
-of carbon included and in other elements added to the mix.
-
-The Minetest default mod doesn't distinguish between types of iron and
-steel at all.  This mod introduces multiple types in order to get a bit
-of complexity and flavour.
-
-Leaving aside explicit addition of other elements, the iron/carbon
-spectrum is here represented by three substances: wrought iron,
-carbon steel, and cast iron.  Wrought iron has low carbon content
-(less than 0.25%), resists shattering, and is easily welded, but is
-relatively soft and susceptible to rusting.  It was used for rails,
-gates, chains, wire, pipes, fasteners, and other purposes.  Cast iron
-has high carbon content (2.1% to 4%), is especially hard, and resists
-corrosion, but is relatively brittle, and difficult to work.  It was used
-to build large structures such as bridges, and for cannons, cookware,
-and engine cylinders.  Carbon steel has medium carbon content (0.25%
-to 2.1%), and intermediate properties: moderately hard and also tough,
-somewhat resistant to corrosion.  It is now used for most of the purposes
-previously satisfied by wrought iron and many of those of cast iron,
-but has historically been especially important for its use in swords,
-armour, skyscrapers, large bridges, and machines.
-
-Historically, the first form of iron to be refined was wrought iron,
-produced from ore by a low-temperature furnace process in which the
-ore/iron remains solid and impurities (slag) are progressively removed.
-Cast iron, by contrast, was produced somewhat later by a high-temperature
-process in a blast furnace, in which the metal is melted, and carbon is
-unavoidably incorporated from the furnace's fuel.  (In fact, it's done
-in two stages, first producing pig iron from ore, and then remelting the
-pig iron to cast as cast iron.)  Carbon steel requires a more advanced
-process, in which molten pig iron is processed to remove the carbon,
-and then a controlled amount of carbon is explicitly mixed back in.
-Other processes are possible to refine iron ore and to adjust its
-carbon content.
-
-Unfortunately, Minetest doesn't let us readily distinguish between
-low-temperature and high-temperature processes: in the default game, the
-same furnace is used both to cook food (low temperature) and to cast metal
-ingots (varying high temperatures).  So we can't sensibly have wrought
-iron and cast iron produced by different types of furnace.  Nor can
-furnace recipes discriminate by which kind of fuel is used (and thus
-by the availability of carbon).  The alloy furnace allows for explicit
-alloying, which appropriately represents how carbon steel is made, but
-is not sensible for the other two, and is a relatively advanced process.
-About the only option to make a second iron-processing furnace process
-readily available is to cook multiple times; happily, this bears a slight
-resemblance to the real process with pig iron as an intermediate product.
-
-The default mod's refined iron, which it calls "steel", is identified
-with this mod's wrought iron.  Cooking an iron lump (representing ore)
-initially produces wrought iron; the cooking process here represents a
-low-temperature bloomery process.  Cooking wrought iron then produces
-cast iron; this time the cooking process represents a blast furnace.
-Alloy cooking wrought iron with coal dust (carbon) produces carbon steel;
-this represents the explicit mixing stage of carbon steel production.
-Additionally, alloy cooking carbon steel with coal dust produces cast
-iron, which is logical but not very useful.  Furthermore, to make it
-possible to turn any of the forms of iron into any other, cooking carbon
-steel or cast iron produces wrought iron, in an abbreviated form of the
-bloomery process.  As usual for metals, the same cooking and alloying
-processes can be performed in parallel forms on ingots or dust.

+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.EU_string(num)`
+	* Converts num to a human-readable string (see pretty_num)
+	  and adds the `EU` unit
+	* Use this function when showing players energy values
+* `technic.pretty_num(num)`
+	* Converts the number `num` to a human-readable string with SI prefixes
+* `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.

+	-- Source: <http://www.wise-uranium.org/rup.html>
+	-- The baseline radioactivity of an isotope is not especially
+	-- correlated with whether it's fissile (i.e., suitable as
+	-- reactor fuel).  Natural uranium consists mainly of fissile
+	-- U-235 and non-fissile U-238, and both U-235 and U-238 are
+	-- significantly radioactive.  U-235's massic activity is
+	-- about 80.0 MBq/kg, and U-238's is about 12.4 MBq/kg, which
+	-- superficially suggests that 3.5%-fissile uranium should have
+	-- only 1.19 times the activity of fully-depleted uranium.
+	-- But a third isotope affects the result hugely: U-234 has
+	-- massic activity of 231 GBq/kg.  Natural uranium has massic
+	-- composition of 99.2837% U-238, 0.711% U-235, and 0.0053% U-234,
+	-- so its activity comes roughly 49% each from U-234 and U-238
+	-- and only 2% from U-235.  During enrichment via centrifuge,
+	-- the U-234 fraction is concentrated along with the U-235, with
+	-- the U-234:U-235 ratio remaining close to its original value.
+	-- (Actually the U-234 gets separated from U-238 slightly more
+	-- than the U-235 is, so the U-234:U-235 ratio is slightly
+	-- higher in enriched uranium.)  A typical massic composition
+	-- for 3.5%-fissile uranium is 96.47116% U-238, 3.5% U-235, and
+	-- 0.02884% U-234.  This gives 3.5%-fissile uranium about 6.55
+	-- times the activity of fully-depleted uranium.  The values we
+	-- compute here for the "radioactive" group value are based on
+	-- linear interpolation of activity along that scale, rooted at
+	-- a natural (0.7%-fissile) uranium block having the activity of
+	-- 9 uranium ore blocks (due to 9 ingots per block).  The group
+	-- value is proportional to the square root of the activity, and
+	-- uranium ore has radioactive=1.  This yields radioactive=1.0
+	-- for a fully-depleted uranium block and radioactive=2.6 for
+	-- a 3.5%-fissile uranium block.

+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.
