Year4000's Launcher is a modified version of SK's Minecraft Launcher. This launcher will let you download the required files to connect to Year4000's servers.
You need to have Maven installed (http://maven.apache.org). Once installed, simply run:
mvn package
Maven will automatically download dependencies for you. Note: For that to work, be sure to add Maven to your "PATH".
