 * A specialized "main" entry point that assumes it will run a specific file
 * (jar-bootstrap.rb) when launching. This allows modifying only the manifest's
 * Main-Class and adding this file to create a self-contained executable JRuby
 * application.
 *
 * Example usage:
 *
 *  * ~/projects/jruby $ cp lib/jruby.jar myapp.jar
 *
 * ~/projects/jruby $ cat jar-bootstrap.rb
 * puts "hello"
 *
 * ~/projects/jruby $ jar ufe myapp.jar org.jruby.JarBootstrapMain jar-bootstrap.rb
 *
 * ~/projects/jruby $ java -jar myapp.jar
 * hello
