In the checked-out directory, use ant with the provided build.xml's "tar" target to generate a distributable tar package for yourself; i.e. issue: `ant tar` in the root directory of your MR checkout/clone. It should appear in the build/ directory. "jar" works for creating jars too. -- Harsh J www.harshj.com
