This module exists solely to package all other gwt modules into a single uber jar. This makes deploying to non-mavenized targets much easier. Of course, you would be wise to inherit your dependencies individually; the uber jar is intended for projects like collide, which have complex configuration, and adding many jars would be a pain.
