 # API
+## Groups
+MineClone 2 makes very extensive use of groups. Making sure your items and objects have the correct group memberships is very important.
+Groups are explained in `GROUPS.md`.
 
 ## Mod naming convention
+Mods mods in MineClone 2 follow a simple naming convention: Mods with the prefix “`mcl_`” are specific to MineClone 2, although they may be based on an existing standalone. Mods which lack this prefix are *usually* verbatim copies of a standalone mod. Some modifications may still have been applied, but the APIs are held compatible.
 
-Mods mods in MineCloneJEpC a simple naming convention: Mods with the prefix
-“`mcljepc_`” are specific to MineCloneJEpC, although they may be based on an
-existing standalone or a mod from a different MineClone fork. Mods which lack
-this prefix are verbatim copies of a standalone mod. Some modifications may
-still have been applied, but the APIs are held compatible.
+## Adding items
+### Special fields
+
+Items can have these fields:
+* `_mcl_generate_description(itemstack)`: Required for any items which manipulate their
+   description in any way. This function takes an itemstack of its own type and must set
+   the proper advanced description for this itemstack. If you don't do this, anvils will
+   fail at properly restoring the description when their custom name gets cleared at an
+   anvil.
+   See `mcl_banners` for an example.
+
+Tools can have these fields:
+* `_mcl_diggroups`: Specifies the digging groups that a tool can dig and how
+  efficiently.  See `_mcl_autogroup` for more information.
+
+All nodes can have these fields:
+
+* `_mcl_hardness`: Hardness of the block, ranges from 0 to infinity (represented by -1). Determines digging times. Default: 0
+* `_mcl_blast_resistance`: How well this block blocks and resists explosions. Default: 0
+* `_mcl_falling_node_alternative`: If set to an itemstring, the node will turn into this node before it starts to fall.
+* `_mcl_after_falling(pos)`: Called after a falling node finished falling and turned into a node.
+
+Use the `mcl_sounds` mod for the sounds.
 
 ## APIs
-A lot of things are possible by using one of the APIs in the mods. Note that not
-all APIs are documented yet, but it is planned. The following APIs should be
-more or less stable but keep in mind that MineCloneJEpC is still unfinished. All
-directory names are relative to `mods/`
+A lot of things are possible by using one of the APIs in the mods. Note that not all APIs are documented yet, but it is planned. The following APIs should be more or less stable but keep in mind that MineClone 2 is still unfinished. All directory names are relative to `mods/`
+
+### Items
+* Doors: `ITEMS/mcl_doors`
+* Fences and fence gates: `ITEMS/mcl_fences`
+* Stairs and slabs: `ITEM/mcl_stairs`
+* Walls: `ITEMS/mcl_walls`
+* Beds: `ITEMS/mcl_beds`
+* Buckets: `ITEMS/mcl_buckets`
+* Dispenser support: `ITEMS/REDSTONE/mcl_dispensers`
+
+### Mobs
+* Mobs: `ENTITIES/mcl_mobs`
+
+MineClone 2 uses its own mobs framework, called “Mobs Redo: MineClone 2 Edition” or “MRM” for short.
+This is a fork of Mobs Redo [`mobs`] by TenPlus1.
+
+You can add your own mobs, spawn eggs and spawning rules with this mod.
+API documnetation is included in `ENTITIES/mcl_mobs/api.txt`.
+
+This mod includes modificiations from the original Mobs Redo. Some items have been removed or moved to other mods.
+The API is mostly identical, but a few features have been added. Compability is not really a goal,
+but function and attribute names of Mobs Redo 1.41 are kept.
+If you have code for a mod which works fine under Mobs Redo, it should be easy to make it work in MineClone 2,
+chances are good that it works out of the box.
+
+### Help
+* Item help texts: `HELP/doc/doc_items`
+* Low-level help entry and category framework: `HELP/doc/doc`
+* Support for lookup tool (required for all entities): `HELP/doc/doc_identifier`
+
+### HUD
+* Statbars: `HUD/hudbars`
+
+### Utility APIs
+* Change player physics: `PLAYER/playerphysics`
+* Select random treasures: `CORE/mcl_loot`
+* Get flowing direction of liquids: `CORE/flowlib`
+* `on_walk_over` callback for nodes: `CORE/walkover` 
+* Get node names close to player (to reduce constant querying): `PLAYER/mcl_playerinfo`
+* Explosion API
+* Music discs API
+* Flowers and flower pots
+
+### Unstable APIs
+The following APIs may be subject to change in future. You could already use these APIs but there will probably be breaking changes in the future, or the API is not as fleshed out as it should be. Use at your own risk!
+
+* Panes (like glass panes and iron bars): `ITEMS/xpanes`
+* `_on_ignite` callback: `ITEMS/mcl_fire`
+* Farming: `ITEMS/mcl_farming`
+* Anything related to redstone: Don't touch (yet)
+* Any other mod not explicitly mentioned above
 
 ### Planned APIs
 
-* Event-based apis to ensure that specific startup code inside of mods can run
-  in the correct order
+* Saplings and trees
+* Custom banner patterns
+* Custom dimensions
+* Custom portals
+* Dispenser and dropper support
+* Proper sky and weather APIs

+
+* `blast_furnace_smeltable=1` : Item or node is smeltable by a blast furnace
+* `smoker_cookable=1` : Food is cookable by a smoker. 
+
+
+## Fake item groups
+These groups put similar items together which should all be treated by the gameplay or the GUI as a single item.
+You should not add custom items to these groups for no good reason, this is likely to cause a ton of conflicts.
+
+* `clock`: Clock (rating indicates the “frame”)
+* `compass`: Compass (rating indicates the “frame”)
+
+This has the following implication: If you want to use a compass or clock in a crafting recipe, you *must*
+use `group:compass` or `group:clock`, respectively.

-Version: 0.1 (in development)
+Version: 0.75 (in development)
 
-SPECIFIC VERSION OF MINECRAFT CLONED: `old_alpha rd-132211`
+### Gameplay
+You start in a randomly-generated world made entirely of cubes. You can explore
+the world and dig and build almost every block in the world to create new
+structures. You can choose to play in a “survival mode” in which you have to
+fight monsters and hunger for survival and slowly progress through the
+various other aspects of the game, such as mining, farming, building machines, and so on
+Or you can play in “creative mode” in which you can build almost anything instantly.
 
-## Purpose and method
-
-### Purpose
-
-The primary purpose of this game is to improove MineClone 2 by researching the
-development of Minecraft through implimenting each important release in-order.
-As a side-effect, this will mean each release is a playable game on it's own -
-but if this project ever catches up to MineClone 2, it will _not_ duplicate
-code, and will avoid cloning the exact version that project is cloning.
-
-### Method
-
-- Make a game that clones the oldest Minecraft release.
-- Make a modpack for each release following, that expands that game to become a
-clone of the modpack's release.
-- Where only absolutely necessary, fork the game to make a release. All future
-modpacks are to be based on the new game. Such an example would be where making
-a change to the `game.conf` file is the only option.
-
-## Gameplay
-You start in a flat world made entirely of cubes. You can explore the world and
-dig almost every block in the world, and can use cobblestone to create new
-structures.
-
-Keeping true to the exact version of Minecraft that this is cloning, it's pretty
-bare. There are only grass and cobblestone blocks. (TODO) Press the action key
-to respawn.
-
-### Gameplay summary
+#### Gameplay summary
 
 * Sandbox-style gameplay, no goals
-* Use blocks to create great buildings, your imagination is the limit
-* You can build almost anything for free (no cost) and without limit
+* Survive: Fight against hostile monsters and hunger
+* Mine for ores and other treasures
+* Magic: Gain experience and enchant your tools
+* Use the collected blocks to create great buildings, your imagination is the limit
+* Collect flowers (and other dye sources) and colorize your world
+* Find some seeds and start farming
+* Find or craft one of hundreds of items
+* Build a railway system and have fun with minecarts
+* Build complex machines with redstone circuits
+* In creative mode you can build almost anything for free and without limits
 
 ## How to play (quick start)
 ### Getting started
-- Mine with right click
-- Place with left click
-- Walk around
+* **Punch a tree** trunk until it breaks and collect wood
+* Place the **wood into the 2×2 grid** (your “crafting grid” in your inventory menu and craft 4 wood planks
+* Place the 4 wood planks in a 2×2 shape in the crafting grid to **make a crafting table**
+* **Rightclick the crafting table** for a 3×3 crafting grid to craft more complex things
+* Use the **crafting guide** (book icon) to learn all the possible crafting recipes
+* **Craft a wooden pickaxe** so you can dig stone
+* Different tools break different kinds of blocks. Try them out!
+* Continue playing as you wish. Have fun!
+
+### Farming
+* Find seeds
+* Craft hoe
+* Rightclick dirt or similar block with hoe to create farmland
+* Place seeds on farmland and watch them grow
+* Collect plant when fully grown
+* If near water, farmland becomes wet and speeds up growth
+
+### Furnace
+* Craft furnace
+* Furnace allows you to obtain more items
+* Upper slot must contain a smeltable item (example: iron ore)
+* Lower slot must contain a fuel item (example: coal)
+* See tooltips in crafting guide to learn about fuels and smeltable items
+
+### Additional help
+More help about the gameplay, blocks items and much more can be found from inside
+the game. You can access the help from your inventory menu.
+
+### Special items
+The following items are interesting for Creative Mode and for adventure
+map builders. They can not be obtained in-game or in the creative inventory.
+
+* Barrier: `mcl_core:barrier`
+
+Use the `/giveme` chat command to obtain them. See the in-game help for
+an explanation.

 ## Target
-
 - Crucially, create a stable, moddable, free/libre clone of Minecraft
-`old_alpha rd-132211` based on the Minetest engine with polished features.
- No other features will be added - though modifications to apis will be, if
- they facilitate making mods or modpacks to expand this game to clone a newer
- version of Minecraft.
+based on the Minetest engine with polished features, usable in both
+singleplayer and multiplayer. Currently, most of **Minecraft Java
+Edition 1.12.2** features are already implemented and polishing existing
+features are prioritized over new feature requests.
+- With lessened priority yet strictly, implement features targetting
+**Minecraft version 1.17 + OptiFine** (OptiFine only as far as supported
+by the Minetest Engine). This means features in parity with the listed
+Minecraft experiences are prioritized over those that don't fulfill this
+scope.
 - Optionally, create a performant experience that will run relatively
 well on really low spec computers. Unfortunately, due to Minecraft's
 mechanisms and Minetest engine's limitations along with a very small
 playerbase on low spec computers, optimizations are hard to investigate.
 
 ## Completion status
-This game is currently in **pre-alpha** stage.
-It is playable, but has a few tweaks left.
+This game is currently in **beta** stage.
+It is playable, but not yet feature-complete.
 Backwards-compability is not entirely guaranteed, updating your world might cause small bugs.
+If you want to use the git version of MineClone2 in production, consider using the production branch.
+It is updated weekly and contains relatively stable code for servers.
 
-These things need figured out, and I don't know how to do them:
+The following main features are available:
 
-* In this edition of minecraft, a left-click places, and a right-click mines.
-  (opposite of later versions, and of Minetest defaults)
-* A way for modpacks to change values in `game.conf` (This will only effect how mods expanding this game function)
-  * mapgen
-  * gamemodes
-  * etc.
+* Tools, weapons
+* Armor
+* Crafting system: 2×2 grid, crafting table (3×3 grid), furnace, including a crafting guide
+* Chests, large chests, ender chests, shulker boxes
+* Furnaces, hoppers
+* Hunger
+* Most monsters and animals
+* All ores from Minecraft
+* Most blocks in the overworld
+* Water and lava
+* Weather
+* 28 biomes
+* The Nether, a fiery underworld in another dimension
+* Redstone circuits (partially)
+* Minecarts (partial)
+* Status effects (partial)
+* Experience
+* Enchanting
+* Brewing, potions, tipped arrow (partial)
+* Boats
+* Fire
+* Buidling blocks: Stairs, slabs, doors, trapdoors, fences, fence gates, walls
+* Clock
+* Compass
+* Sponge
+* Slime block
+* Small plants and saplings
+* Dyes
+* Banners
+* Deco blocks: Glass, stained glass, glass panes, iron bars, hardened clay (and colors), heads and more
+* Item frames
+* Jukeboxes
+* Beds
+* Inventory menu
+* Creative inventory
+* Farming
+* Writable books
+* Commands
+* Villages
+* The End
+* And more!
 
-The following main features are available (including features I must now remove):
+The following features are incomplete:
 
-* Blocks in the overworld
-* Buidling blocks: Stone, Dirt
-* Commands (TO BE REMOVED)
+* Some monsters and animals
+* Redstone-related things
+* Special minecarts
+* A couple of non-trivial blocks and items
+
+Bonus features (not found in Minecraft 1.12):
+
+* Built-in crafting guide which shows you crafting and smelting recipes
+* In-game help system containing extensive help about gameplay basics, blocks, items and more
+* Temporary crafting recipes. They only exist to make some otherwise unaccessible items available when you're not in creative mode. These recipes will be removed as development goes on an more features become available
+* Saplings in chests in mapgen v6
 * Fully moddable (thanks to Minetest's powerful Lua API)
-* And more! (It's a lot of work to remove - but not so much anymore thanks to ROllerozxa)
+* New blocks and items:
+    * Lookup tool, shows you the help for whatever it touches
+    * More slabs and stairs
+    * Nether Brick Fence Gate
+    * Red Nether Brick Fence
+    * Red Nether Brick Fence Gate
 
 Technical differences from Minecraft:
 
 * Height limit of ca. 31000 blocks (much higher than in Minecraft)
 * Horizontal world size is ca. 62000×62000 blocks (much smaller than in Minecraft, but it is still very large)
 * Still very incomplete and buggy
-* Blocks, items and other features that shouldn't be there
+* Blocks, items, enemies and other features are missing
 * A few items have slightly different names to make them easier to distinguish
+* Different music for jukebox
 * Different textures (Pixel Perfection)
-* Different sounds (various sources) (TO BE REMOVED)
+* Different sounds (various sources)
 * Different engine (Minetest)
 * Different easter eggs
 
-… and finally, MineCloneJEpC is free software (“free” as in “freedom”)!
+… and finally, MineClone2 is free software (“free” as in “freedom”)!

+# MineClone 2
+一個非官方的Minetest遊戲，遊玩方式和Minecraft類似。由davedevils從MineClone分拆。
+由許多人開發。並非由Mojang Studios開發。<!-- "Mojang AB"'s Name changed at 2020/05, main README should change too -->
+
+版本：0.71.0
+
+### 遊玩
+你開始在一個完全由方塊隨機生成的世界裡。你可以探索這個世界，挖掘和建造世界上幾乎所有的方塊，以創造新的結構。你可以選擇在「生存模式」中進行遊戲，在這個模式中，你必須與怪物戰鬥，飢餓求生，並在遊戲的其他各個環節中慢慢進步，如採礦、養殖、建造機器等等。
+
+或者你也可以在「創造模式」中玩，在這個模式中，你可以瞬間建造大部分東西。
+#### Gameplay summary
+
+* 沙盒式遊戲，沒有明確目標
+* 生存：與怪物和飢餓搏鬥
+* 挖礦來獲得礦物和寶物
+* 附魔：獲得經驗值並以附魔強化你的工具
+* 使用收集的方塊來創造偉大的建築
+* 收集鮮花（和其他染料來源），令世界多姿多彩
+* 找些種子並開始耕種
+* 尋找或合成數百個物品之一
+* 建立一個鐵路系統，並從礦車中得到樂趣
+* 用紅石電路建造複雜的機器
+* 在創造模式下，你幾乎可以免費建造任何東西，而且沒有限制。
+
+## 如何開始
+### 開始生存
+* **挖樹幹**直到其破裂並收集木材
+* 將木頭**放入2×2的格子中**（你的物品欄中的「合成格子」），然後製作4塊木材。
+* 將4塊木材按2×2的形狀擺放在合成格子裡，製作成合成臺。
+* **右鍵單擊製作臺**以獲得3×3製作網格，製作更複雜的東西
+* 使用**合成指南**（書形圖標）了解所有可能的合成方式
+* **製作一個木鎬**，這樣你就可以挖石頭了。
+* 不同的工具可以打破不同種類的方塊。試試吧！
+* 繼續玩你想玩的。盡情享受吧！
+
+### 耕種
+* 找到種子
+* 合成鋤頭
+* 用鋤頭右鍵點擊泥土或類似的方塊，創建農田
+* 將種子放在農田上，看著它們長出來
+* Collect plant when fully grown
+* If near water, farmland becomes wet and speeds up growth
+
+### Furnace
+* Craft furnace
+* Furnace allows you to obtain more items
+* Upper slot must contain a smeltable item (example: iron ore)
+* Lower slot must contain a fuel item (example: coal)
+* See tooltips in crafting guide to learn about fuels and smeltable items
+
+### Additional help
+More help about the gameplay, blocks items and much more can be found from inside
+the game. You can access the help from your inventory menu.
+
+### Special items
+The following items are interesting for Creative Mode and for adventure
+map builders. They can not be obtained in-game or in the creative inventory.
+
+* Barrier: `mcl_core:barrier`
+
+Use the `/giveme` chat command to obtain them. See the in-game help for
+an explanation.
+
+#### Incomplete items
+These items do not work yet, but you can get them with `/giveme` for testing:
+
+* Minecart with Chest: `mcl_minecarts:chest_minecart`
+* Minecart with Furnace: `mcl_minecarts:furnace_minecart`
+* Minecart with Hopper: `mcl_minecarts:hopper_minecart`
+* Minecart with Command Block: `mcl_minecarts:command_block_minecart`
+
+## Installation
+This game requires [Minetest](http://minetest.net) to run (version 5.0.0 or
+later). So you need to install Minetest first. Only stable versions of Minetest
+are officially supported.
+There is no support for running MineClone 2 in development versions of Minetest.
+
+To install MineClone 2 (if you haven't already), move this directory into the
+“games” directory of your Minetest data directory. Consult the help of
+Minetest to learn more.
+
+## Project description
+The main goal of **MineClone 2** is to be a clone of Minecraft and to be released as free software.
+
+* **開發目標：我的世界, Java版, 版本 1.12**
+* MineClone2還包括Minetest支持的Optifine功能。
+* 後期Minecraft版本的功能可能會偷偷加入，但它們的優先級較低。
+* 總的來說，Minecraft的目標是在Minetest目前允許的情況下進行克隆。
+* 克隆Minecraft是最優先的。
+* MineClone2將使用不同的圖形和聲音，但風格相似。
+* 克隆界面沒有優先權。只會被粗略地模仿。
+* 在Minetest中發現的局限性將在開發過程中被記錄和報告。
+
+## 完成程度
+該遊戲目前處於**alpha**階段。
+它是可玩的，但尚未完成，預計會出現許多錯誤。
+向後兼容性是**不能保證的**，更新你的世界可能會造成大大小小的bug（比如「缺少節點」的錯誤甚至崩潰）。
+
+已經實現以下功能：
+
+* 工具，武器
+* 盔甲
+* 合成和熔煉系統：2×2 合成格, 合成臺 (3×3 合成格), 熔爐, 合成教學

+This mod automatically adds groups to items based on item metadata.
+
+Specifically, this mod has 2 purposes:
+1) Automatically adding the group “solid” for blocks considered “solid” in Minecraft.
+2) Generating digging time group for all nodes based on node metadata (it's complicated)
+
+This mod also requires another mod called “mcl_autogroup” to function properly.
+“mcl_autogroup” exposes the API used to register digging groups, while this mod
+uses those digging groups to set the digging time groups for all the nodes and
+tools.
+
+See init.lua for more infos.
+
+The leading underscore in the name “_mcl_autogroup” was added to force Minetest to load this mod as late as possible.

+--[[
+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:
+
+1) The block's hardness
+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.
+
+How the mod is used
+===================
+
+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).
+
+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.
+
+    _mcl_diggroups = {

+
+The "uses" field indicate how many uses (0 for infinite) a tool has when used on
+the specified digging group.  The "speed" field is a multiplier to the dig speed
+on that digging group.
+
+The "level" field indicates which levels of the group the tool can harvest.  A
+level of 0 means that the tool cannot harvest blocks of that node.  A level of 1
+or above means that the tool can harvest nodes with that level or below.  See
+"mcl_tools/init.lua" for examples on how "_mcl_diggroups" is used in practice.
+
+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.

+## v6 mapgen functions
+These are functions for the v6 mapgen only.
+
+Use these functions only in worlds in which the v6 mapgen is used.
+If you use these in any other mapgen, bad things might happen.
+
+### `biomeinfo.get_v6_humidity(pos)`
+Get the biome humidity at pos (for v6 mapgen).
+
+### `biomeinfo.get_v6_heat(pos)`
+Get the biome heat/temperature at pos (for v6 mapgen).
+
+### `biomeinfo.get_v6_biome(pos)`
+Get the v6 biome at pos.
+Returns a string, which is the unique biome name.
+
+Note: This function currently ignores the `biomeblend` v6 mapgen flag,
+it just pretends this setting is disabled.
+This is normally not a problem, but at areas where biomes blend,
+the result is not perfectly accurate and just an estimate.
+
+### `biomeinfo.get_active_v6_biomes()`
+Returns a table containing the names of all v6 biomes that are actively
+used in the current world, e.g. those that have been activated
+by the use of the mapgen v6 flags (`mgv6_spflags`).
+
+### `biomeinfo.all_v6_biomes`
+This is a table containing all v6 biomes (as strings), even those that
+might not be used in the current world.
+
+### v6 biome names
+
+These are the biome names used in this mod:
+
+* Normal
+* Desert
+* Jungle
+* Tundra
+* Taiga

+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301
+    USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random
+  Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!
