/**
 * Combine the os-package with the Application plugin. Currently heavily opinionated to where
 * the code will live, though that is slightly configurable using the ospackage-application extension.
 *
 * TODO Make a base plugin, so that this plugin can require os-package
 *
 * Usage:
 * 
 *     User has to provide a mainClassName
 *     
User has to create SystemPackaging tasks, the easiest way is to apply plugin: 'os-package'
 *
