| * Use this script to build and package S4 apps. |
| * |
| * Run 'gradle install' on the s4 project to publish to your local maven repo. |

| * TODO: This should probably be distributed as an s4 plugin for Gradle. |
| * TODO: There seem to be to be similarities with the war and jetty plugins. (war -> s4r, jetty -> s4Run). |
| * We should make it easy to test the app from this script by a running a test task that starts and stops |
| * an s4 server. See: http://www.gradle.org/releases/1.0-milestone-3/docs/userguide/userguide_single.html#war_plugin |
