Bump version to 1.100.4

There's a couple of alternative ways to solve this. Ideally we'd send
our network messages at the same time as MC does
(ChunkManager.playerLoadedChunk), but this'd require a mixin.

Instead we just rely on the fact that if the chunk isn't loaded,
monitors won't have done anything and so we don't need to send their
contents!

Fixes #1047, probably doesn't cause any regressions. I've not seen any
issues on 1.16, but I also hadn't before so ¯\_(ツ)_/¯.

+# 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"`.

-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 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.
 
-## What?
-CC: Tweaked 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: Tweaked aims to be a nurturing ground for various features, with
-a pull request against the original mod being the end goal.
-
-CC: Tweaked 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.
-
-## Relation to CCTweaks?
-This mod has nothing to do with CCTweaks, though there is no denying the name is a throwback to it. However, I do plan
-to migrate some features of CCTweaks into CC: Tweaked.
+CC: Tweaked can be installed from [CurseForge] or [Modrinth]. It requires the [Minecraft Forge][forge] mod loader, but
+[versions are available for Fabric][ccrestitched].
 
 ## Contributing
-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.
+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).
 
-That being said, in order to start helping develop CC: Tweaked, you'll need to follow these steps:
+## 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.
 
- - **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).
- 
-If you want to run CC: Tweaked in a normal Minecraft instance, run `./gradlew build` and copy the `.jar` from 
-`build/libs`.
+We also host fairly comprehensive documentation at [tweaked.cc](https://tweaked.cc/ "The CC: Tweaked website").
+
+## 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/).

+
+# Playing audio with speakers
+CC: Tweaked's speaker peripheral provides a powerful way to play any audio you like with the @{speaker.playAudio}
+method. However, for people unfamiliar with digital audio, it's not the most intuitive thing to use. This guide provides
+an introduction to digital audio, demonstrates how to play music with CC: Tweaked's speakers, and then briefly discusses
+the more complex topic of audio processing.
+
+## A short introduction to digital audio
+When sound is recorded it is captured as an analogue signal, effectively the electrical version of a sound
+wave. However, this signal is continuous, and so can't be used directly by a computer. Instead, we measure (or *sample*)
+the amplitude of the wave many times a second and then *quantise* that amplitude, rounding it to the nearest
+representable value.
+
+This representation of sound - a long, uniformally sampled list of amplitudes is referred to as [Pulse-code
+Modulation][PCM] (PCM). PCM can be thought of as the "standard" audio format, as it's incredibly easy to work with. For
+instance, to mix two pieces of audio together, you can just add samples from the two tracks together and take the average.
+
+CC: Tweaked's speakers also work with PCM audio. It plays back 48,000 samples a second, where each sample is an integer
+between -128 and 127. This is more commonly referred to as 48kHz and an 8-bit resolution.
+
+Let's now look at a quick example. We're going to generate a [Sine Wave] at 220Hz, which sounds like a low monotonous
+hum. First we wrap our speaker peripheral, and then we fill a table (also referred to as a *buffer*) with 128×1024
+samples - this is the maximum number of samples a speaker can accept in one go.
+
+In order to fill this buffer, we need to do a little maths. We want to play 220 sine waves each second, where each sine
+wave completes a full oscillation in 2π "units". This means one seconds worth of audio is 2×π×220 "units" long. We then
+need to split this into 48k samples, basically meaning for each sample we move 2×π×220/48k "along" the sine curve.
+
+```lua {data-peripheral=speaker}
+local speaker = peripheral.find("speaker")
+
+local buffer = {}
+local t, dt = 0, 2 * math.pi * 220 / 48000
+for i = 1, 128 * 1024 do
+    buffer[i] = math.floor(math.sin(t) * 127)
+    t = (t + dt) % (math.pi * 2)
+end
+
+speaker.playAudio(buffer)
+```
+
+## Streaming audio
+You might notice that the above snippet only generates a short bit of audio - 2.7s seconds to be precise. While we could
+try increasing the number of loop iterations, we'll get an error when we try to play it through the speaker: the sound
+buffer is too large for it to handle.
+
+Our 2.7 seconds of audio is stored in a table with over 130 _thousand_ elements. If we wanted to play a full minute of
+sine waves (and why wouldn't you?), you'd need a table with almost 3 _million_. Suddenly you find these numbers adding
+up very quickly, and these tables take up more and more memory.
+
+Instead of building our entire song (well, sine wave) in one go, we can produce it in small batches, each of which get
+passed off to @{speaker.playAudio} when the time is right. This allows us to build a _stream_ of audio, where we read
+chunks of audio one at a time (either from a file or a tone generator like above), do some optional processing to each
+one, and then play them.
+
+Let's adapt our example from above to do that instead.
+
+```lua {data-peripheral=speaker}
+local speaker = peripheral.find("speaker")
+
+local t, dt = 0, 2 * math.pi * 220 / 48000
+while true do
+    local buffer = {}
+    for i = 1, 16 * 1024 * 8 do
+        buffer[i] = math.floor(math.sin(t) * 127)
+        t = (t + dt) % (math.pi * 2)
+    end
+
+    while not speaker.playAudio(buffer) do
+        os.pullEvent("speaker_audio_empty")
+    end
+end
+```
+
+It looks pretty similar to before, aside from we've wrapped the generation and playing code in a while loop, and added a
+rather odd loop with @{speaker.playAudio} and @{os.pullEvent}.
+
+Let's talk about this loop, why do we need to keep calling @{speaker.playAudio}? Remember that what we're trying to do
+here is avoid keeping too much audio in memory at once. However, if we're generating audio quicker than the speakers can
+play it, we're not helping at all - all this audio is still hanging around waiting to be played!
+
+In order to avoid this, the speaker rejects any new chunks of audio if its backlog is too large. When this happens,
+@{speaker.playAudio} returns false. Once enough audio has played, and the backlog has been reduced, a
+@{speaker_audio_empty} event is queued, and we can try to play our chunk once more.
+
+## Storing audio
+PCM is a fantastic way of representing audio when we want to manipulate it, but it's not very efficient when we want to
+store it to disk. Compare the size of a WAV file (which uses PCM) to an equivalent MP3, it's often 5 times the size.
+Instead, we store audio in special formats (or *codecs*) and then convert them to PCM when we need to do processing on
+them.
+
+Modern audio codecs use some incredibly impressive techniques to compress the audio as much as possible while preserving
+sound quality. However, due to CC: Tweaked's limited processing power, it's not really possible to use these from your
+computer. Instead, we need something much simpler.
+
+DFPWM (Dynamic Filter Pulse Width Modulation) is the de facto standard audio format of the ComputerCraft (and
+OpenComputers) world. Originally popularised by the addon mod [Computronics], CC:T now has built-in support for it with
+the @{cc.audio.dfpwm} module. This allows you to read DFPWM files from disk, decode them to PCM, and then play them
+using the speaker.
+
+Let's dive in with an example, and we'll explain things afterwards:
+
+```lua {data-peripheral=speaker}
+local dfpwm = require("cc.audio.dfpwm")
+local speaker = peripheral.find("speaker")
+
+local decoder = dfpwm.make_decoder()
+for chunk in io.lines("data/example.dfpwm", 16 * 1024) do
+    local buffer = decoder(chunk)
+
+    while not speaker.playAudio(buffer) do
+        os.pullEvent("speaker_audio_empty")
+    end
+end
+```
+
+Once again, we see the @{speaker.playAudio}/@{speaker_audio_empty} loop. However, the rest of the program is a little
+different.
+
+First, we require the dfpwm module and call @{cc.audio.dfpwm.make_decoder} to construct a new decoder. This decoder
+accepts blocks of DFPWM data and converts it to a list of 8-bit amplitudes, which we can then play with our speaker.
+
+As mentioned to above, @{speaker.playAudio} accepts at most 128×1024 samples in one go. DFPMW uses a single bit for each
+sample, which means we want to process our audio in chunks of 16×1024 bytes (16KiB). In order to do this, we use
+@{io.lines}, which provides a nice way to loop over chunks of a file. You can of course just use @{fs.open} and
+@{fs.BinaryReadHandle.read} if you prefer.
+
+## Processing audio
+As mentioned near the beginning of this guide, PCM audio is pretty easy to work with as it's just a list of amplitudes.
+You can mix together samples from different streams by adding their amplitudes, change the rate of playback by removing
+samples, etc...
+
+Let's put together a small demonstration here. We're going to add a small delay effect to the song above, so that you
+hear a faint echo about a second later.
+
+In order to do this, we'll follow a format similar to the previous example, decoding the audio and then playing it.
+However, we'll also add some new logic between those two steps, which loops over every sample in our chunk of audio, and
+adds the sample from one second ago to it.
+
+For this, we'll need to keep track of the last 48k samples - exactly one seconds worth of audio. We can do this using a
+[Ring Buffer], which helps makes things a little more efficient.
+
+```lua {data-peripheral=speaker}
+local dfpwm = require("cc.audio.dfpwm")
+local speaker = peripheral.find("speaker")
+
+-- Speakers play at 48kHz, so one second is 48k samples. We first fill our buffer
+-- with 0s, as there's nothing to echo at the start of the track!
+local samples_i, samples_n = 1, 48000
+local samples = {}
+for i = 1, samples_n do samples[i] = 0 end
+
+local decoder = dfpwm.make_decoder()
+for chunk in io.lines("data/example.dfpwm", 16 * 1024) do
+    local buffer = decoder(chunk)
+
+    for i = 1, #buffer do
+        local original_value = buffer[i]
+
+        -- Replace this sample with its current amplitude plus the amplitude from one second ago.
+        -- We scale both to ensure the resulting value is still between -128 and 127.
+        buffer[i] = original_value * 0.6 + samples[samples_i] * 0.4
+
+        -- Now store the current sample, and move the "head" of our ring buffer forward one place.
+        samples[samples_i] = original_value
+        samples_i = samples_i + 1
+        if samples_i > samples_n then samples_i = 1 end
+    end
+
+    while not speaker.playAudio(buffer) do
+        os.pullEvent("speaker_audio_empty")
+    end
+end
+```
+
+:::note Confused?
+Don't worry if you don't understand this example. It's quite advanced, and does use some ideas that this guide doesn't
+cover. That said, don't be afraid to ask on [Discord] or [IRC] either!
+:::
+
+It's worth noting that the examples of audio processing we've mentioned here are about manipulating the _amplitude_ of
+the wave. If you wanted to modify the _frequency_ (for instance, shifting the pitch), things get rather more complex.
+For this, you'd need to use the [Fast Fourier transform][FFT] to convert the stream of amplitudes to frequencies,
+process those, and then convert them back to amplitudes.
+
+This is, I'm afraid, left as an exercise to the reader.

+# Reusing code with require
+A library is a collection of useful functions and other definitions which is stored separately to your main program. You
+might want to create a library because you have some functions which are used in multiple programs, or just to split
+your program into multiple more modular files.
+
+Let's say we want to create a small library to make working with the @{term|terminal} a little easier. We'll provide two
+functions: `reset`, which clears the terminal and sets the cursor to (1, 1), and `write_center`, which prints some text
+in the middle of the screen.
+
+Start off by creating a file called `more_term.lua`:
+
+```lua {data-snippet=more_term}
+local function reset()
+  term.clear()
+  term.setCursorPos(1, 1)
+end
+
+local function write_center(text)
+  local x, y = term.getCursorPos()
+  local width, height = term.getSize()
+  term.setCursorPos(math.floor((width - #text) / 2) + 1, y)
+  term.write(text)
+end
+
+return { reset = reset, write_center = write_center }
+```
+
+Now, what's going on here? We define our two functions as one might expect, and then at the bottom return a table with
+the two functions. When we require this library, this table is what is returned. With that, we can then call the
+original functions. Now create a new file, with the following:
+
+```lua {data-mount=more_term:more_term.lua}
+local more_term = require("more_term")
+more_term.reset()
+more_term.write_center("Hello, world!")
+```
+
+When run, this'll clear the screen and print some text in the middle of the first line.
+
+## require in depth
+While the previous section is a good introduction to how @{require} operates, there are a couple of remaining points
+which are worth mentioning for more advanced usage.
+
+### Libraries can return anything
+In our above example, we return a table containing the functions we want to expose. However, it's worth pointing out
+that you can return ''anything'' from your library - a table, a function or even just a string! @{require} treats them
+all the same, and just returns whatever your library provides.
+
+### Module resolution and the package path
+In the above examples, we defined our library in a file, and @{require} read from it. While this is what you'll do most
+of the time, it is possible to make @{require} look elsewhere for your library, such as downloading from a website or
+loading from an in-memory library store.
+
+As a result, the *module name* you pass to @{require} doesn't correspond to a file path. One common mistake is to load
+code from a sub-directory using `require("folder/library")` or even `require("folder/library.lua")`, neither of which
+will do quite what you expect.
+
+When loading libraries (also referred to as *modules*) from files, @{require} searches along the *@{package.path|module
+path}*. By default, this looks something like:
+
+* `?.lua`
+* `?/init.lua`
+* `/rom/modules/main/?.lua`
+* etc...
+
+When you call `require("my_library")`, @{require} replaces the `?` in each element of the path with your module name, and
+checks if the file exists. In this case, we'd look for `my_library.lua`, `my_library/init.lua`,
+`/rom/modules/main/my_library.lua` and so on. Note that this works *relative to the current program*, so if your
+program is actually called `folder/program`, then we'll look for `folder/my_library.lua`, etc...
+
+One other caveat is loading libraries from sub-directories. For instance, say we have a file
+`my/fancy/library.lua`. This can be loaded by using `require("my.fancy.library")` - the '.'s are replaced with '/'
+before we start looking for the library.
+
+## External links
+There are several external resources which go into require in a little more detail:
+
+ - The [Lua Module tutorial](http://lua-users.org/wiki/ModulesTutorial) on the Lua wiki.
+ - [Lua's manual section on @{require}](https://www.lua.org/manual/5.1/manual.html#pdf-require).

+# ![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

+#       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

+#
+#   Important for patching:

+#   (2) This script targets any POSIX shell, so it avoids extensions provided

+#
+#       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;

-<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>
-

-	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.

-* 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>
- * <li>{@link LuaValue#invoke(Varargs)}</li>
- * <li>{@link LuaValue#method(String)}</li>
- * <li>{@link LuaValue#method(String,LuaValue)}</li>
- * <li>{@link LuaValue#invokemethod(String)}</li>
- * <li>{@link LuaValue#invokemethod(String,Varargs)}</li>
- * <li> ...</li>

- * {@link #JSTR_NAN}, {@link #JSTR_POSINF}, and {@link #JSTR_NEGINF} may be useful 
- * when dealing with Nan or Infinite values.
