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!

Note: DataView is not yet implemented in Gecko. It is implemented in Chrome 9.
An ArrayBuffer is a useful object for representing an arbitrary chunk of data. In many cases, such data will be read from disk or from the network, and will not follow the alignment restrictions that are imposed on the Typed Array Views described earlier. In addition, the data will often be heterogeneous in nature and have a defined byte order.
The DataView view provides a low-level interface for reading such data from and writing it to an ArrayBuffer.
