-# Contributing to CC: Tweaked
-As with many open source projects, CC: Tweaked thrives on contributions from other people! This document (hopefully)
-provides an introduction as to how to get started in helping out.
-
-If you've any other questions, [just ask the community][community] or [open an issue][new-issue].
-
-## Reporting issues
-If you have a bug, suggestion, or other feedback, the best thing to do is [file an issue][new-issue]. When doing so,
-do use the issue templates - they provide a useful hint on what information to provide.
-
-## Translations
-Translations are managed through [Weblate], an online interface for managing language strings. This is synced
-automatically with GitHub, so please don't submit PRs adding/changing translations!
-
-## Developing
-In order to develop CC: Tweaked, you'll need to download the source code and then run it. This is a pretty simple
-process. When building on Windows, Use `gradlew.bat` instead of `./gradlew`.
-
- - **Clone the repository:** `git clone https://github.com/cc-tweaked/CC-Tweaked.git && cd CC-Tweaked`
- - **Setup Forge:** `./gradlew build`
- - **Run Minecraft:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).
- - **Optionally:** For small PRs (especially those only touching Lua code), it may be easier to use GitPod, which
-   provides a pre-configured environment: [![Gitpod ready-to-code](https://img.shields.io/badge/Gitpod-ready--to--code-2b2b2b?logo=gitpod)](https://gitpod.io/#https://github.com/cc-tweaked/CC-Tweaked/)
-
-   Do note you will need to download the mod after compiling to test.
-
-If you want to run CC:T in a normal Minecraft instance, run `./gradlew build` and copy the `.jar` from `build/libs`.
-These commands may take a few minutes to run the first time, as the environment is set up, but should be much faster
-afterwards.
-
-The following sections describe the more niche sections of CC: Tweaked's build system. Some bits of these are
-quite-complex, and (dare I say) over-engineered, so you may wish to ignore them. Well tested/documented PRs are always
-preferred (and I'd definitely recommend setting up the tooling if you're doing serious development work), but for
-small changes it can be a lot.
-
-### Code linters
-CC: Tweaked uses a couple of "linters" on its source code, to enforce a consistent style across the project. While these
-are run whenever you submit a PR, it's often useful to run this before committing.
-
- - **[Checkstyle]:** Checks Java code to ensure it is consistently formatted. This can be run with `./gradlew build` or
-   `./gradle check`.
- - **[illuaminate]:** Checks Lua code for semantic and styleistic issues. See [the usage section][illuaminate-usage] for
-   how to download and run it. You may need to generate the Java documentation stubs (see "Documentation" below) for all
-   lints to pass.
-
-### Documentation
-When writing documentation for [CC: Tweaked's documentation website][docs], it may be useful to build the documentation
-and preview it yourself before submitting a PR.
-
-Building all documentation is, sadly, a multi-stage process (though this is largely hidden by Gradle). First we need to
-convert Java doc-comments into Lua ones, we also generate some Javascript to embed. All of this is then finally fed into
-illuaminate, which spits out our HTML.
-
-#### Setting up the tooling
-For various reasons, getting the environment set up to build documentation can be pretty complex. I'd quite like to
-automate this via Docker and/or nix in the future, but this needs to be done manually for now.
-
-This tooling is only needed if you need to build the whole website. If you just want to generate the Lua stubs, you can
-skp this section.
- - Install Node/npm and install our Node packages with `npm ci`.
- - Install [illuaminate][illuaminate-usage] as described above.
-
-#### Building documentation
-Gradle should be your entrypoint to building most documentation. There's two tasks which are of interest:
-
- - `./gradlew luaJavadoc` - Generate documentation stubs for Java methods.
- - `./gradlew docWebsite` - Generate the whole website (including Javascript pages). The resulting HTML is stored at
-   `./build/docs/lua/`.
-
-#### Writing documentation
-illuaminate's documentation system is not currently documented (somewhat ironic), but is _largely_ the same as
-[ldoc][ldoc]. Documentation comments are written in Markdown,
-
-Our markdown engine does _not_ support GitHub flavoured markdown, and so does not support all the features one might
-expect (such as tables). It is very much recommended that you build and preview the docs locally first.
-
-### Testing
-Thankfully running tests is much simpler than running the documentation generator! `./gradlew check` will run the
-entire test suite (and some additional bits of verification).
-
-Before we get into writing tests, it's worth mentioning the various test suites that CC: Tweaked has:
- - "Core" Java (`./src/test/java`): These test core bits of the mod which don't require any Minecraft interaction.
-   This includes the `@LuaFunction` system, file system code, etc...
-
-   These tests are run by `./gradlew test`.
-
- - CraftOS (`./src/test/resources/test-rom/`): These tests are written in Lua, and ensure the Lua environment, libraries
-   and programs work as expected. These are (generally) written to be able to be run on emulators too, to provide some
-   sort of compliance test.
-
-   These tests are run by the '"Core" Java' test suite, and so are also run with `./gradlew test`.
-
- - In-game (`./src/testMod/java/dan200/computercraft/ingame/`): These tests are run on an actual Minecraft server and client,
-   using [the same system Mojang do][mc-test]. The aim of these is to test in-game behaviour of blocks and peripherals.
-
-   These are run by `./gradlew testClient` and `./gradlew testServer`. You may want to run the client under `xvfb-run`
-   or similar when running in a headless environment.
-
-## CraftOS tests
-CraftOS's tests are written using a test system called "mcfly", heavily inspired by [busted] (and thus RSpec). Groups of
-tests go inside `describe` blocks, and a single test goes inside `it`.
-
-Assertions are generally written using `expect` (inspired by Hamcrest and the like). For instance, `expect(foo):eq("bar")`
-asserts that your variable `foo` is equal to the expected value `"bar"`.

+[![Build Status](https://travis-ci.org/SquidDev-CC/CC-Tweaked.svg?branch=master)](https://travis-ci.org/SquidDev-CC/CC-Tweaked)
 
-CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles and more to the game. A fork of the
-much-beloved [ComputerCraft], it continues its legacy with better performance, stability, and a wealth of new features.
+CC: Tweaked is a fork of ComputerCraft which aims to provide earlier access to the more experimental and in-development
+features of the mod. For a more stable experience, I recommend checking out the
+[original mod](https://github.com/dan200/ComputerCraft).
 
-CC: Tweaked can be installed from [CurseForge] or [Modrinth]. It requires the [Minecraft Forge][forge] mod loader, but
-[versions are available for Fabric][ccrestitched].
+## What?
+CC: Tweaked (or CC:T for short) does not aim to create a competing fork of ComputerCraft, nor am I planning to take it
+in in a vastly different direction to the original mod. In fact, CC:T aims to be a nurturing ground for various
+features, with a pull request against the original mod being the end goal.
+
+CC:T also includes many pull requests from the community which have not yet been merged, offering a large number
+of additional bug fixes and features over the original mod.
+
+## Features
+CC: Tweaked contains the all features of the latest alpha, as well as numerous fixes, performance improvements and
+several additional features. I'd recommend checking out [the releases page](https://github.com/SquidDev-CC/CC-Tweaked/releases)
+to see the full changes, but here's a couple of the more interesting changes:
+
+ - Replace LuaJ with Cobalt.
+ - Allow running multiple computers at the same time.
+ - Websocket support in the HTTP library.
+ - Wired modems and cables act more like multiparts.
+ - Add map-like rendering for pocket computers and printed pages/books.
+ - Adds the `/computercraft` command, offering various diagnostic tools for server owners. This allows operators to
+   track which computers are hogging resources, turn on and shutdown multiple computers at once and interact with
+   computers remotely.
+ - Add full-block wired modems, allowing one to wrap non-solid peripherals (such as turtles, or chests if Plethora is
+   installed).
+
+## Relation to CCTweaks?
+This mod has nothing to do with CCTweaks, though there is no denying the name is a throwback to it. That being said,
+several features have been included, such as full block modems, the Cobalt runtime and map-like rendering for pocket
+computers.
 
 ## Contributing
-Any contribution is welcome, be that using the mod, reporting bugs or contributing code. If you want to get started
-developing the mod, [check out the instructions here](CONTRIBUTING.md#developing).
+Any contribution is welcome, be that using the mod, reporting bugs or contributing code. If you do wish to contribute
+code, do consider submitting it to the ComputerCraft repository instead.
 
-## Community
-If you need help getting started with CC: Tweaked, want to show off your latest project, or just want to chat about
-ComputerCraft we have a [forum](https://forums.computercraft.cc/) and [Discord guild](https://discord.computercraft.cc)!
-There's also a fairly populated, albeit quiet [IRC channel](http://webchat.esper.net/?channels=computercraft), if that's
-more your cup of tea.
+That being said, in order to start helping develop CC:T, you'll need to follow these steps:
 
-We also host fairly comprehensive documentation at [tweaked.cc](https://tweaked.cc/ "The CC: Tweaked website").
+ - **Clone the repository:** `git clone https://github.com/SquidDev-CC/CC-Tweaked.git && cd CC-Tweaked`
+ - **Setup Forge:** `./gradlew setupDecompWorkspace`
+ - **Test your changes:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).
 
-## Using
-CC: Tweaked is hosted on my maven repo, and so is relatively simple to depend on. You may wish to add a soft (or hard)
-dependency in your `mods.toml` file, with the appropriate version bounds, to ensure that API functionality you depend
-on is present.
-
-```groovy
-repositories {
-  maven {
-    url 'https://squiddev.cc/maven/'
-    content {
-      includeGroup 'org.squiddev'
-    }
-  }
-}
-
-dependencies {
-  implementation fg.deobf("org.squiddev:cc-tweaked-${mc_version}:${cct_version}")
-}
-```
-
-You should also be careful to only use classes within the `dan200.computercraft.api` package. Non-API classes are
-subject to change at any point. If you depend on functionality outside the API, file an issue, and we can look into
-exposing more features.
-
-We bundle the API sources with the jar, so documentation should be easily viewable within your editor. Alternatively,
-the generated documentation [can be browsed online](https://tweaked.cc/javadoc/).

-# ![CC: Tweaked](logo.png)
-CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles and more to the game. A fork of the
-much-beloved [ComputerCraft], it continues its legacy with better performance, stability, and a wealth of new features.
-
-CC: Tweaked can be installed from [CurseForge] or [Modrinth]. It requires the [Minecraft Forge][forge] mod loader, but
-[versions are available for Fabric][ccrestitched].
-
-## Features
-Controlled using the [Lua programming language][lua], CC: Tweaked's computers provides all the tools you need to start
-writing code and automating your Minecraft world.
-
-![A ComputerCraft terminal open and ready to be programmed.](images/basic-terminal.png){.big-image}
-
-While computers are incredibly powerful, they're rather limited by their inability to move about. *Turtles* are the
-solution here. They can move about the world, placing and breaking blocks, swinging a sword to protect you from zombies,
-or whatever else you program them to!
-
-![A turtle tunneling in Minecraft.](images/turtle.png){.big-image}
-
-Not all problems can be solved with a pickaxe though, and so CC: Tweaked also provides a bunch of additional peripherals
-for your computers. You can play a tune with speakers, display text or images on a monitor, connect all your
-computers together with modems, and much more.
-
-Computers can now also interact with inventories such as chests, allowing you to build complex inventory and item
-management systems.
-
-![A chest's contents being read by a computer and displayed on a monitor.](images/peripherals.png){.big-image}
-
-## Getting Started
-While ComputerCraft is lovely for both experienced programmers and for people who have never coded before, it can be a
-little daunting getting started. Thankfully, there's several fantastic tutorials out there:
-
- - [Direwolf20's ComputerCraft tutorials](https://www.youtube.com/watch?v=wrUHUhfCY5A "ComputerCraft Tutorial Episode 1 - HELP! and Hello World")
- - [Sethbling's ComputerCraft series](https://www.youtube.com/watch?v=DSsx4VSe-Uk "Programming Tutorial with Minecraft Turtles -- Ep. 1: Intro to Turtles and If-Then-Else_End")
- - [Lyqyd's Computer Basics 1](http://www.computercraft.info/forums2/index.php?/topic/15033-computer-basics-i/ "Computer Basics I")
-
-Once you're a little more familiar with the mod, the sidebar and links below provide more detailed documentation on the
-various APIs and peripherals provided by the mod.
-
-If you get stuck, do pop in to the [Minecraft Computer Mod Discord guild][discord] or ComputerCraft's
-[IRC channel][irc].

-#
-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

+<h1>1 - <a name="1">Introduction</a></h1>
+<h2>Goals of Luaj</h2>
+Luaj is a lua interpreter based on the 5.1.x version of lua with the following goals in mind:
+<ul>
+<li>Java-centric implementation of lua vm built to leverage standard Java features.
+<li>Lightweight, high performance execution of lua. 
+<li>Multi-platform to be able to run on JME, JSE, or JEE environments. 
+<li>Complete set of libraries and tools for integration into real-world projects.
+<li>Dependable due to sufficient unit testing of vm and library features. 
+</ul>
+
+<h2>Differences with 1.0</h2>
+In addition to the basic goals of luaj, version 2.0 is aimed 
+at improving on the 1.0 vm in the following aspects. 
+<ul>
+<li>Support for compiling lua source code into Java source code.
+<li>Support for compiling lua bytecode directly into Java bytecode.
+<li>Improved performance of of lua bytecode processing.
+<li>Stackless vm design centered around dynamically typed objects.
+<li>More alignment with C API (see <a href="names.csv">names.csv</a> for details)
+<li>Improved class and package naming conventions. 
+<li>Improved unit tests of core classes. 
+<li>Improved quality due to major redesign and rewrite of core elements. 
+<li>More complete implementation including weak keys and values, and all metatags. 
+</ul>
+
+<h2>Performance</h2>
+Good performance is a major goal of luaj.  
+The following table provides measured execution times on a subset of benchmarks from 
+<a href="http://shootout.alioth.debian.org/">the computer language benchmarks game</a>  
+in comparison with the standard C distribution.

+
+Luaj in interpreted mode performs well for the benchmarks, and even better when source-to-source (lua2java) 
+or bytecode-to-bytecode (luajc) compilers are used, 
+and actually executes <em>faster</em> than C-based lua in some cases.  
+It is also faster than Java-lua implementations Jill, Kahlua, and Mochalua for all benchmarks tested.  
+
+<h1>2 - <a name="2">Simple Examples</a></h1>
+
+<h2>Run a lua script in Java SE</h2>
+
+<p>
+From the main distribution directory line type:
+
+<pre>
+	java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/hello.lua
+</pre>
+
+<p>
+You should see the following output:
+<pre>
+	hello, world
+</pre>
+
+To see how luaj can be used to acccess most Java API's including swing, try:
+
+<pre>
+	java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/swingapp.lua
+</pre>
+
+<h2>Compile lua source to lua bytecode</h2>
+
+<p>
+From the main distribution directory line type:
+
+<pre>
+	java -cp lib/luaj-jse-2.0.3.jar luac examples/lua/hello.lua
+	java -cp lib/luaj-jse-2.0.3.jar lua luac.out
+</pre>
+
+<p>
+The compiled output "luac.out" is lua bytecode and should run and produce the same result.
+
+<h2>Compile lua source to java source</h2>
+
+<p>
+Luaj can compile to lua source code to Java source code:
+
+<pre>
+	java -cp lib/luaj-jse-2.0.3.jar lua2java -s examples/lua -d . hello.lua
+	javac -cp lib/luaj-jse-2.0.3.jar hello.java
+	java -cp &quot;lib/luaj-jse-2.0.3.jar;.&quot; lua -l hello
+</pre>
+
+<p>
+The output <em>hello.java</em> is Java source, that implements the logic in hello.lua directly.
+Once <em>hello.java</em> is compiled into <em>hello.class</em> it can be required and used in place of the original lua script, but with better performance.  
+There are no additional dependencies for compiling or running source-to-source compiled lua. 
+
+<p>
+Lua scripts can also be run directly in this mode without precompiling using the <em>lua</em> command with the <b><em>-j</em></b> option when run in JDK 1.5 or higher:
+<pre>
+	java -cp lib/luaj-jse-2.0.3.jar lua -j examples/lua/hello.lua
+</pre>
+
+<h2>Compile lua bytecode to java bytecode</h2>
+
+<p>
+Luaj can compile lua sources or binaries directly to java bytecode if the bcel library is on the class path. From the main distribution directory line type:
+
+<pre>
+	ant bcel-lib
+	java -cp &quot;lib/luaj-jse-2.0.3.jar;lib/bcel-5.2.jar&quot; luajc -s examples/lua -d . hello.lua
+	java -cp &quot;lib/luaj-jse-2.0.3.jar;.&quot; lua -l hello
+</pre>
+
+<p>
+The output <em>hello.class</em> is Java bytecode, should run and produce the same result.
+There is no runtime dependency on the bcel library, 
+but the compiled classes must be in the class path at runtime, unless runtime jit-compiling via luajc and bcel are desired (see later sections).
+
+<p>
+Lua scripts can also be run directly in this mode without precompiling using the <em>lua</em> command with the <b><em>-b</em></b> option and providing the <em>bcel</em> library in the class path:
+<pre>
+	java -cp &quot;lib/luaj-jse-2.0.3.jar;lib/bcel-5.2.jar&quot; lua -b examples/lua/hello.lua
+</pre>
+
+
+<h2>Run a script in a Java Application</h2>
+
+<p>
+The following pattern is used within Java SE
+
+<pre>
+	import org.luaj.vm2.*;
+	import org.luaj.vm2.lib.jse.*;
+
+	String script = "examples/lua/hello.lua";
+	LuaValue _G = JsePlatform.standardGlobals();
+	_G.get("dofile").call( LuaValue.valueOf(script) );
+</pre>
+
+<p>
+A simple example may be found in
+<pre>
+	examples/jse/SampleJseMain.java
+</pre>
+
+<p>
+You must include the library <b>lib/luaj-jse-2.0.3.jar</b> in your class path.
+
+<h2>Run a script in a MIDlet</h2>
+
+<p>
+The for MIDlets the <em>JmePlatform</em> is used instead:
+
+<pre>
+	import org.luaj.vm2.*;
+	import org.luaj.vm2.lib.jme.*;
+
+	String script = "examples/lua/hello.lua";
+	LuaValue _G = JmePlatform.standardGlobals();
+	_G.get("dofile").call( LuaValue.valueOf(script) );
+</pre>
+
+<p>
+The file must be a resource within within the midlet jar for <em>dofile()</em> to find it.
+Any files included via <em>require()</em> must also be part of the midlet resources.
+
+<p>
+A simple example may be found in
+<pre>
+	examples/jme/SampleMIDlet.java
+</pre>
+
+<p>
+You must include the library <b>lib/luaj-jme-2.0.3.jar</b> in your midlet jar.
+
+<p>
+An ant script to build and run the midlet is in
+<pre>
+	build-midlet.xml
+</pre>
+
+<p>
+You must install the wireless toolkit and define <em>WTK_HOME</em> for this script to work. 
+
+<h2>Run a script using JSR-223 Dynamic Scripting</h2>
+
+<p>
+The standard use of JSR-223 scripting engines may be used:
+
+<pre>
+	ScriptEngineManager mgr = new ScriptEngineManager();
+	ScriptEngine e = mgr.getEngineByExtension(".lua");
+	e.put("x", 25);
+	e.eval("y = math.sqrt(x)");
+	System.out.println( "y="+e.get("y") );
+</pre>
+
+<p>
+All standard aspects of script engines including compiled statements should be supported.
+
+<p>
+You must include the library <b>lib/luaj-jse-2.0.3.jar</b> in your class path.
+
+<p>
+A working example may be found in
+<pre>
+	examples/jse/ScriptEngineSample.java
+</pre>
+
+To compile and run it using Java 1.6 or higher:
+
+<pre>
+	javac examples/jse/ScriptEngineSample.java
+	java -cp &quot;lib/luaj-jse-2.0.3.jar;examples/jse&quot; ScriptEngineSample
+</pre>
+
+<h2>Excluding the lua bytecode compiler</h2>
+
+By default, the compiler is included whenever <em>standardGlobals()</em> or <em>debugGlobals()</em> are called.  
+Without a compiler, files can still be executed, but they must be compiled elsewhere beforehand.
+The "luac" utility is provided in the jse jar for this purpose, or a standard lua compiler can be used.  
+
+<p>
+To exclude the lua-to-lua-bytecode compiler, do not call 
+<em>standardGlobals()</em> or <em>debugGlobals()</em> 
+but instead initialize globals with including only those libraries 
+that are needed and omitting the line:
+<pre>
+	org.luaj.vm2.compiler.LuaC.install();
+</pre>
+
+
+<h2>Including the Lua2Java lua-source-to-Java-source compiler</h2>
+
+<p>
+To compile from lua sources to Java sources for all lua loaded at runtime, 
+install the Lua2Java compiler <em>after</em> globals have been created using:
+
+<pre>
+	org.luaj.vm2.jse.lua2java.Lua2Java.install();
+</pre>
+
+This uses the system Java compiler to compile from Java source to Java bytecode, 
+and cannot compile lua binary files containing lua bytecode at runtime. 
+
+<h2>Including the LuaJC lua-bytecode-to-Java-bytecode compiler</h2>
+
+<p>
+To compile from lua to Java bytecode for all lua loaded at runtime, 
+install the LuaJC compiler <em>after</em> globals have been created using:
+
+<pre>
+	org.luaj.vm2.jse.luajc.LuaJC.install();
+</pre>
+
+<p>
+This will compile all lua bytecode into Java bytecode, regardless of if they are loaded as
+lua source or lua binary files.
+
+<p>
+The requires <em>bcel</em> to be on the class path, and the ClassLoader of JSE or CDC.  
+
+<h1>3 - <a name="3">Concepts</a></h1>
+
+<h2>Globals</h2>
+The old notion of platform has been replaced with creation of globals. 
+Two classes are provided to encapsulate common combinations of libraries.  
+
+<h3>JsePlatform</h3>
+
+This class can be used as a factory for globals in a typical Java SE application. 
+All standard libraries are included, as well as the luajava library. 
+The default search path is the current directory,
+and the math operations include all those supported by Java SE.
+
+<h3>JmePlatform</h3>
+
+This class can be used to set up the basic environment for a Java ME application.
+The default search path is limited to the jar resources,
+and the math operations are limited to those supported by Java ME.
+All libraries are included except luajava, and the os, io, and math libraries are 
+limited to those functions that can be supported on that platform.
+
+
+<h1>4 - <a name="4">Libraries</a></h1>
+
+<h2>Standard Libraries</h2>
+
+Libraries are coded to closely match the behavior specified in 
+See <a href="http://www.lua.org/manual/5.1/">standard lua documentation</a> for details on the library API's
+
+<p>
+The following libraries are loaded by both <em>JsePlatform.standardGlobals()</em> and <em>JmePlatform.standardGlobals()</em>:
+<pre>	base
+	coroutine
+	io
+	math
+	os
+	package
+	string
+	table
+</pre>
+
+<p>
+The <em>JsePlatform.standardGlobals()</em> globals also include:
+<pre>	luajava 
+</pre>
+
+<p>
+The <em>JsePlatform.debugGlobals()</em> and <em>JsePlatform.debugGlobals()</em> functions produce globals that include:
+<pre>	debug
+</pre>
+
+<h3>I/O Library</h3>
+The implementation of the <em>io</em> library differs by platform owing to platform limitations.
+
+<p>
+The <em>JmePlatform.standardGlobals()</em> instantiated the io library <em>io</em> in 
+<pre>
+	src/jme/org/luaj/vm2/lib/jme/JmeIoLib.java
+</pre>
+
+The <em>JsePlatform.standardGlobals()</em> includes support for random access and is in 
+<pre>
+	src/jse/org/luaj/vm2/lib/jse/JseIoLib.java
+</pre>
+
+<h3>OS Library</h3>
+The implementation of the <em>os</em> library also differs per platform.
+
+<p>
+The basic <em>os</em> library implementation us used by <em>JmePlatform</em> and is in:
+<pre>
+	src/core/org/luaj/lib/OsLib.java
+</pre>
+
+A richer version for use by <em>JsePlatform</em> is : 
+<pre>
+	src/jse/org/luaj/vm2/lib/jse/JseOsLib.java
+</pre>
+
+Time is a represented as number of milliseconds since the epoch, 
+and most time and date formatting, locales, and other features 
+are not implemented.
+
+<h3>Coroutine Library</h3>
+The <em>coroutine</em> library is implemented using one JavaThread per coroutine.   
+This allows <em>coroutine.yield()</em> can be called from anywhere, 
+as with the yield-from-anywhere patch in C-based lua. 
+
+<p>
+Luaj uses WeakReferences and the OrphanedThread error to ensure that coroutines that are no longer referenced 
+are properly garbage collected.  For thread safety, OrphanedThread should not be caught by Java code.  
+See <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaThread.html">LuaThread</a>
+and <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/OrphanedThread.html">OrphanedThread</a>
+javadoc for details. 
+
+<h3>Debug Library</h3>
+The <em>debug</em> library is not included by default by 
+<em>JmePlatform.standardGlobals()</em> or <em>JsePlatform.standardGlobsls()</em> .
+
+The functions <em>JmePlatform.debugGlobals()</em> and <em>JsePlatform.debugGlobsls()</em> 
+create globals that contain the debug library in addition to the other standard libraries. 
+
+To install dynamically from lua use java-class-based require:</em>:
+<pre>
+	require 'org.luaj.vm2.lib.DebugLib'
+</pre>
+
+The <em>lua</em> command line utility includes the <em>debug</em> library by default.
+
+
+<h3>The Luajava Library</h3>
+The <em>JsePlatform.standardGlobals()</em> includes the <em>luajava</em> library, which simplifies binding to Java classes and methods.  
+It is patterned after the original <a href="http://www.keplerproject.org/luajava/">luajava project</a>.
+
+<p>
+The following lua script will open a swing frame on Java SE:
+<pre>
+	jframe = luajava.bindClass( "javax.swing.JFrame" )
+	frame = luajava.newInstance( "javax.swing.JFrame", "Texts" );
+	frame:setDefaultCloseOperation(jframe.EXIT_ON_CLOSE)
+	frame:setSize(300,400)
+	frame:setVisible(true)
+</pre>
+
+<p>
+See a longer sample in <em>examples/lua/swingapp.lua</em> for details, including a simple animation loop, rendering graphics, mouse and key handling, and image loading. 
+Or try running it using: 
+<pre>
+	java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/swingapp.lua
+</pre>
+
+<p>
+The Java ME platform does not include this library, and it cannot be made to work because of the lack of a reflection API in Java ME. 
+
+<p>
+The <em>lua</em> connand line tool includes <em>luajava</em>. 
+
+<h1>5 - <a name="5">LuaJ API</a></h1>
+
+<h2>API Javadoc</h2>
+The javadoc for the main classes in the LuaJ API are on line at
+<pre>
+	 <a href="http://luaj.sourceforge.net/api/2.0/index.html">http://luaj.sourceforge.net/api/2.0</a>
+</pre>
+
+You can also build a local version from sources using 
+<pre>
+	 ant doc
+</pre>
+
+<h2>LuaValue and Varargs</h2>
+All lua value manipulation is now organized around 
+<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaValue.html">LuaValue</a>
+which exposes the majority of interfaces used for lua computation.  
+<pre>
+	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaValue.html">org.luaj.vm2.LuaValue</a>
+</pre>
+
+<h3>Common Functions</h3>
+<em>LuaValue</em> exposes functions for each of the operations in LuaJ.  
+Some commonly used functions and constants include:
+<pre>
+	call();               // invoke the function with no arguments
+	call(LuaValue arg1);  // call the function with 1 argument
+	invoke(Varargs arg);  // call the function with variable arguments, variable return values
+	get(int index);       // get a table entry using an integer key
+	get(LuaValue key);    // get a table entry using an arbitrary key, may be a LuaInteger
+	rawget(int index);    // raw get without metatable calls
+	valueOf(int i);       // return LuaValue corresponding to an integer
+	valueOf(String s);    // return LuaValue corresponding to a String
+	toint();              // return value as a Java int
+	tojstring();          // return value as a Java String
+	isnil();              // is the value nil
+	NIL;                  // the value nil
+	NONE;                 // a Varargs instance with no values	 
+</pre>
+
+<h2>Varargs</h2>
+The interface <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">Varargs</a> provides an abstraction for 
+both a variable argument list and multiple return values.  
+For convenience, <em>LuaValue</em> implements <em>Varargs</em> so a single value can be supplied anywhere 
+variable arguments are expected.      
+<pre>
+	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">org.luaj.vm2.Varargs</a>
+</pre>
+
+<h3>Common Functions</h3>
+<em>Varargs</em> exposes functions for accessing elements, and coercing them to specific types:
+<pre>
+	narg();                 // return number of arguments
+	arg1();                 // return the first argument
+	arg(int n);             // return the nth argument
+	isnil(int n);           // true if the nth argument is nil
+	checktable(int n);      // return table or throw error
+	optlong(int n,long d);  // return n if a long, d if no argument, or error if not a long
+</pre>
+ 
+See the <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">Varargs</a> API for a complete list.
+ 
+<h2>LibFunction</h2>
+The simplest way to implement a function is to choose a base class based on the number of arguments to the function.
+LuaJ provides 5 base classes for this purpose, depending if the function has 0, 1, 2, 3 or variable arguments, 
+and if it provide multiple return values.   
+<pre>
+	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/ZeroArgFunction.html">org.luaj.vm2.lib.ZeroArgFunction</a>
+	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/OneArgFunction.html">org.luaj.vm2.lib.OneArgFunction</a>
+	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/TwoArgFunction.html">org.luaj.vm2.lib.TwoArgFunction</a>
+	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/ThreeArgFunction.html">org.luaj.vm2.lib.ThreeArgFunction</a>
+	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/VarArgFunction.html">org.luaj.vm2.lib.VarArgFunction</a>
+</pre>
+
+Each of these functions has an abstract method that must be implemented, 
+and argument fixup is done automatically by the classes as each Java function is invoked.
+
+<p>
+For example, to implement a &quot;hello, world&quot; function, we could supply:
+<pre>
+	pubic class hello extends ZeroArgFunction {
+		public LuaValue call() {
+			env.get("print").call(valueOf("hello, world"));
+		}
+	}
+</pre>
+
+The value <em>env</em> is the environment of the function, and is normally supplied 
+by the instantiating object whenever default loading is used. 
+
+<p>
+Calling this function from lua could be done by:
+<pre> 
+	require( 'hello' )()
+</pre>
+
+while calling this function from Java would look like:
+<pre> 
+	new hello().call();
+</pre>
+
+Note that in both the lua and Java case, extra arguments will be ignored, and the function will be called.  
+Also, no virtual machine instance is necessary to call the function. 
+To allow for arguments, or return multiple values, extend one of the other base classes. 
+ 
+<h2>Closures</h2>
+Closures still exist in this framework, but are optional, and are only used to implement lua bytecode execution.  
+
+<h1>6 - <a name="6">Parser</a></h1>
+
+<h2>Javacc Grammar</h2>
+A Javacc grammarwas developed to simplify the creation of Java-based parsers for the lua language.
+The grammar is specified for <a href="https://javacc.dev.java.net/">javacc version 5.0</a> because that tool generates standalone 
+parsers that do not require a separate runtime.     
+
+<p>
+A plain undecorated grammer that can be used for validation is available in <a href="grammar/Lua51.jj">grammar/Lua51.jj</a>
+while a grammar that generates a typed parse tree is in  <a href="grammar/LuaParser.jj">grammar/LuaParser.jj</a>
+
+<h2>Creating a Parse Tree from Lua Source</h2>
+The default lu compiler does a single-pass compile of lua source to lua bytecode, so no explicit parse tree is produced.  
+
+<p>
+To simplify the creation of abstract syntax trees from lua sources, the LuaParser class is generated as part of the JME build.  
+To use it, provide an input stream, and invoke the root generator, which will return a Chunk if the file is valid, 
+or throw a ParseException if there is a syntax error.
+
+<p>
+For example, to parse a file and print all variable names, use code like:
+<pre>
+	try {
+		String file = "main.lua";
+		LuaParser parser = new LuaParser(new FileInputStream(file));
+		Chunk chunk = parser.Chunk();
+		chunk.accept( new Visitor() {
+			public void visit(Exp.NameExp exp) {
+				System.out.println("Name in use: "+exp.name.name);
+			}
+		} );
+	} catch ( ParseException e ) {
+		System.out.println("parse failed: " + e.getMessage() + "\n"
+			+ "Token Image: '" + e.currentToken.image + "'\n"
+			+ "Location: " + e.currentToken.beginLine + ":" + e.currentToken.beginColumn 
+			         + "-" + e.currentToken.endLine + "," + e.currentToken.endColumn);
+	}
+</pre> 
+In luaj 2.0.3 error reporting was turned on in the parser so line numbers are avaiable for most parse exceptions.
+This example may be found in
+<pre>
+	examples/jse/SampleParser.java
+</pre>
+
+<p>
+See the <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/ast/package-summary.html">org.luaj.vm2.ast package</a> javadoc for the API relating to the syntax tree that is produced. 
+
+<h1>7 - <a name="7">Building and Testing</a></h1>
+
+<h2>Building the jars</h2>
+An ant file is included in the root directory which builds the libraries by default.
+
+<p>
+Other targets exist for creating distribution file an measuring code coverage of unit tests.
+
+<h2>Unit tests</h2>
+
+<p>
+The main luaj JUnit tests are organized into a JUnit 3 suite:
+<pre>
+	test/junit/org/luaj/vm2/AllTests.lua
+</pre>
+
+<p>
+Unit test scripts can be found in these locations
+<pre>

+	test/junit/org/luaj/vm2/compiler/regressions.zip
+	test/junit/org/luaj/vm2/vm1/luajvm1-tests.zip
+</pre>
+
+<h2>Code coverage</h2>
+
+<p>
+A build script for running unit tests and producing code coverage statistics is in 
+<pre>
+	build-coverage.xml
+</pre>
+
+It relies on the cobertura code coverage library.

+* Class to manage loading of {@link Prototype} instances.
+* <p>
+* The {@link LoadState} class exposes one main function, 
+* namely {@link #load(InputStream, String, LuaValue)}, 
+* to be used to load code from a particular input stream.  
+* <p>
+* A simple pattern for loading and executing code is
+* <pre> {@code
+* LuaValue _G = JsePlatform.standardGlobals();
+* LoadState.load( new FileInputStream("main.lua"), "main.lua", _G ).call();
+* } </pre>
+* This should work regardless of which {@link LuaCompiler}
+* has been installed.
+* <p>
+*  
+* Prior to loading code, a compiler should be installed. 
+* <p>
+* By default, when using {@link JsePlatform} or {@JmePlatform}
+* to construct globals, the {@link LuaC} compiler is installed. 
+* <p>
+* To override the default compiler with, say, the {@link LuaJC}
+* lua-to-java bytecode compiler, install it before loading, 
+* for example:
+* <pre> {@code
+* LuaValue _G = JsePlatform.standardGlobals();
+* LuaJC.install();
+* LoadState.load( new FileInputStream("main.lua"), "main.lua", _G ).call();
+* } </pre>

+ * Extension of {@link LuaFunction} which executes lua bytecode. 
+ * <p>
+ * A {@link LuaClosure} is a combination of a {@link Prototype} 
+ * and a {@link LuaValue} to use as an environment for execution. 
+ * <p>
+ * There are three main ways {@link LuaClosure} instances are created:
+ * <ul> 
+ * <li>Construct an instance using {@link #LuaClosure(Prototype, LuaValue)}</li>
+ * <li>Construct it indirectly by loading a chunk via {@link LuaCompiler#load(java.io.InputStream, String, LuaValue)}
+ * <li>Execute the lua bytecode {@link Lua#OP_CLOSURE} as part of bytecode processing
+ * </ul>
+ * <p>
+ * To construct it directly, the {@link Prototype} is typically created via a compiler such as {@link LuaC}:
+ * <pre> {@code
+ * InputStream is = new ByteArrayInputStream("print('hello,world').getBytes());
+ * Prototype p = LuaC.instance.compile(is, "script");
+ * LuaValue _G = JsePlatform.standardGlobals()
+ * LuaClosure f = new LuaClosure(p, _G);
+ * }</pre> 
+ * <p>
+ * To construct it indirectly, the {@link LuaC} compiler may be used, 
+ * which implements the {@link LuaCompiler} interface: 
+ * <pre> {@code
+ * LuaFunction f = LuaC.instance.load(is, "script", _G);
+ * }</pre>
+ * <p>
+ * Typically, a closure that has just been loaded needs to be initialized by executing it, 
+ * and its return value can be saved if needed:
+ * <pre> {@code
+ * LuaValue r = f.call();
+ * _G.set( "mypkg", r ) 
+ * }</pre>
+ * <p> 
+ * In the preceding, the loaded value is typed as {@link LuaFunction} 
+ * to allow for the possibility of other compilers such as {@link LuaJC}
+ * producing {@link LuaFunction} directly without 
+ * creating a {@link Prototype} or {@link LuaClosure}.
+ * <p> 
+ * Since a {@link LuaClosure} is a {@link LuaFunction} which is a {@link LuaValue}, 
+ * all the value operations can be used directly such as:
+ * <ul>
+ * <li>{@link LuaValue#setfenv(LuaValue)}</li>
+ * <li>{@link LuaValue#call()}</li>
+ * <li>{@link LuaValue#call(LuaValue)}</li>
+ * <li>{@link LuaValue#invoke()}</li>
