/**
* Apache S4 Application Build File
*
* Use this script to buils 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
*
* This is an interesting discussion:
* http://gradle.1045684.n5.nabble.com/Exclude-properties-file-from-war-td3365147.html
