 /**

  * Merges the binaries produced by <code>JarCollector</code> and compress them using Pack200.

  * This mojo delegates the work to <code>Packer</code>, which can be invoked from the command

  * line without Maven. Maven invocation syntax is:

  *

  * <blockquote><code>mvn org.geotoolkit.project:geotk-jar-collector:pack --non-recursive</code></blockquote>

  *

  * Do not forget the <code>--non-recursive</code> option, otherwise the Mojo will be executed

  * many time.
