The Antlion distribution, as of Antlion 0.8.0, comes with a Jar file containing "optional" tasks. These classes are classified as optional extensions to Antlion due to their additional library requirements, much like Ant.

To add these optional tasks into your Ant build, you simply need to add the optional jar into the Antlion classpath, along with the other required libraries. These required libraries can also be added to the base Ant lib directory.
