This folder has third-party or otherwise external libraries needed for other parts to work.
## classparser
A simplistic parser for Java class files.
This library has served as a base for some (much more full-featured and advanced) work under NDA for AVG. It, however, should NOT be confused with that work.

## hoedown
Hoedown is a revived fork of Sundown, the Markdown parser based on the original code of the Upskirt library by Natacha Porté.
See [github repo](https://github.com/hoedown/hoedown).
## iconfix
This was originally part of the razor-qt project and the Qt toolkit, respecitvely. Its sole purpose is to reimplement Qt's icon loading logic to prevent it from using any platform plugins that could break icon loading.

## javacheck
Simple Java tool that prints the JVM details - version and platform bitness.
Do what you want with it. It is so trivial that noone cares.
## launcher
Java launcher part for Minecraft.
It:
* Starts a process
* Waits for a launch script on stdin
* Consumes the launch script you feed it
* Proceeds with launch when it gets the `launcher` command
This means the process is essentially idle until the final command is sent. You can, for example, attach a profiler before you send it.
A `legacy` and `onesix` launchers are available.
*`legacy` is intended for use with Minecraft versions <1.6andisdeprecated.
*`onesix` can handle launching any Minecraft version, at the cost of some extra features `legacy` enables (custom window icon and title).
libnbt++ is a free C++ library for Minecraft's file format Named Binary Tag (NBT). It can read and write compressed and uncompressed NBT files and provides a code interface for working with NBT data.
See [github repo](https://github.com/ljfa-ag/libnbtplusplus).
Available either under LGPL version 3 or later.
## pack200
Unpacks pack200 archives (squished, compression-optimized Java jars). This format is only used by Forge to save bandwidth.
A horrible little thing extracted from the depths of the OpenJDK codebase. Please don't look at it, or you will praise Cthulhu for his clean code for the rest of your days.
Available under GPL 2 with classpath exception.
## rainbow
Color functions extracted from [KGuiAddons](https://inqlude.org/libraries/kguiaddons.html). Used for adaptive text coloring.
Available either under LGPL version 2.1 or later.
## xz-embedded
Tiny implementation of LZMA2 de/compression. This format is only used by Forge to save bandwidth.
BSD licensed, derived from [qt-google-analytics](https://github.com/HSAnet/qt-google-analytics).
Modifications include better handling of IP anonymization (can be enabled) and general improvements of the API (application handles persistence and ID generation instead of the library).
