Everything needed to run a comprehensive dev environment. Just type X_ and pick a service from autocomplete; new dev modules will be added as they are built. The only dev service not included in the uber jar is xapi-dev-maven, as it includes all runtime dependencies of maven, adding ~4 seconds to build time, and 6 megabytes to the final output jar size (without xapi-dev-maven, it's ~1MB).

The newest version!
