+Minecraft Forge: Credits/Thank You
+
+Forge is a set of tools and modifications to the Minecraft base game code to assist 
+mod developers in creating new and exciting content. It has been in development for 
+several years now, but I would like to take this time thank a few people who have 
+helped it along it's way.
+
+First, the people who originally created the Forge projects way back in Minecraft 
+alpha. Eloraam of RedPower, and SpaceToad of Buildcraft, without their acceptiance 
+of me taking over the project, who knows what Minecraft modding would be today.
+
+Secondly, someone who has worked with me, and developed some of the core features
+that allow modding to be as functional, and as simple as it is, cpw. For developing
+FML, which stabelized the client and server modding ecosystem. As well as the base
+loading system that allows us to modify Minecraft's code as elegently as possible.
+
+Mezz, who has stepped up as the issue and pull request manager. Helping to keep me
+sane as well as guiding the community into creating better additions to Forge.
+
+Searge, Bspks, Fesh0r, ProfMobious, and all the rest over on the MCP team {of which 
+I am a part}. For creating some of the core tools needed to make Minecraft modding 
+both possible, and as stable as can be.
+  On that note, here is some specific information of the MCP data we use:
+    * Minecraft Coder Pack (MCP) *
+      Forge Mod Loader and Minecraft Forge have permission to distribute and automatically 
+      download components of MCP and distribute MCP data files. This permission is not 
+      transitive and others wishing to redistribute the Minecraft Forge source independently
+      should seek permission of MCP or remove the MCP data files and request their users 
+      to download MCP separately.
+      
+And lastly, the countless community members who have spent time submitting bug reports, 
+pull requests, and just helping out the community in general. Thank you.
+
+--LexManos

+=========================================================================
+
+This is Forge Mod Loader.
+
+You can find the source code at all times at https://github.com/MinecraftForge/MinecraftForge/tree/1.12.x/src/main/java/net/minecraftforge/fml
+
+This minecraft mod is a clean open source implementation of a mod loader for minecraft servers
+and minecraft clients.
+
+The code is authored by cpw.
+
+It began by partially implementing an API defined by the client side ModLoader, authored by Risugami.
+http://www.minecraftforum.net/topic/75440-
+This support has been dropped as of Minecraft release 1.7, as Risugami no longer maintains ModLoader.
+
+It also contains suggestions and hints and generous helpings of code from LexManos, author of MinecraftForge.
+http://www.minecraftforge.net/
+
+Additionally, it contains an implementation of topological sort based on that 
+published at http://keithschwarz.com/interesting/code/?dir=topological-sort
+
+It also contains code from the Maven project for performing versioned dependency
+resolution. http://maven.apache.org/
+
+It also contains a partial repackaging of the javaxdelta library from http://sourceforge.net/projects/javaxdelta/
+with credit to it's authors.
+
+Forge Mod Loader downloads components from the Minecraft Coder Pack
+(http://mcp.ocean-labs.de/index.php/Main_Page) with kind permission from the MCP team.

-#   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/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
