---[[ Mining times. Yeah, mining times … Alright, this is going to be FUN!

+This mod implements a HACK to make 100% sure the digging times of all tools
+match Minecraft's perfectly.  The digging times system of Minetest is very
+different, so this weird group trickery has to be used.  In Minecraft, each
+block has a hardness and the actual Minecraft digging time is determined by
+this:
 
-This mod does include a HACK to make 100% sure the digging times of all tools match Minecraft's perfectly.
-The digging times system of Minetest is very different, so this weird group trickery has to be used.
-In Minecraft, each block has a hardness and the actual Minecraft digging time is determined by this:
 1) The block's hardness
-2) The tool being used
-3) Whether the tool is considered as “eligible” for the block
+2) The tool being used (the tool speed and its efficiency level)
+3) Whether the tool is considered as "eligible" for the block
    (e.g. only diamond pick eligible for obsidian)
-See Minecraft Wiki <http://minecraft.gamepedia.com/Minecraft_Wiki> for more information.
 
-In MineClone 2, all diggable node have the hardness set in the custom field “_mcl_hardness” (0 by default).
-The nodes are also required to specify the “eligible” tools in groups like “pickaxey”, “shovely”, etc.
-This mod then calculates the real digging time based on the node meta data. The real digging times
-are then added into mcl_autogroup.digtimes where the table indices are group rating and the values are the
-digging times in seconds. These digging times can be then added verbatim into the tool definitions.
+See Minecraft Wiki <http://minecraft.gamepedia.com/Minecraft_Wiki> for more
+information.
 
-Example:
-mcl_autogroup.digtimes.pickaxey_dig_diamond[1] = 0.2
+How the mod is used
+===================
 
-→ This means that when a node has been assigned the group “pickaxey_dig_diamond=1”, it can be dug by the
-diamond pickaxe in 0.2 seconds.
+In MineClone 2, all diggable nodes have the hardness set in the custom field
+"_mcl_hardness" (0 by default).  These values are used together with digging
+groups by this mod to create the correct digging times for nodes.  Digging
+groups are registered using the following code:
 
+    mcl_autogroup.register_diggroup("shovely")
+    mcl_autogroup.register_diggroup("pickaxey", {
+        levels = { "wood", "gold", "stone", "iron", "diamond" }
+    })
 
+The first line registers a simple digging group.  The second line registers a
+digging group with 5 different levels (in this case one for each material of a
+pickaxes).
 
-This strange setup with mcl_autogroup has been done to minimize the amount of required digging times
-a single tool needs to use. If this is not being done, the loading time will increase considerably
-(>10s).
+Nodes indicate that they belong to a particular digging group by being member of
+the digging group in their node definition.  "mcl_core:dirt" for example has
+shovely=1 in its groups.  If the digging group has multiple levels the value of
+the group indicates which digging level the node requires.
+"mcl_core:stone_with_gold" for example has pickaxey=4 because it requires a
+pickaxe of level 4 be mined.
 
-]]
+For tools to be able to dig nodes of digging groups they need to use the have
+the custom field "_mcl_diggroups" function to get the groupcaps.  The value of
+this field is a table which defines which groups the tool can dig and how
+efficiently.

+Information about the mod
+=========================
+
+The mod is split up into two parts, mcl_autogroup and _mcl_autogroup.
+mcl_autogroup contains the API functions used to register custom digging groups.
+_mcl_autogroup contains most of the code.  The leading underscore in the name
+"_mcl_autogroup" is used to force Minetest to load that part of the mod as late
+as possible.  Minetest loads mods in reverse alphabetical order.
+
+This also means that it is very important that no mod adds _mcl_autogroup as a
+dependency.
