 * A runtime target handler is used when associating a runtime with

 * on the projects - adding or removing files, setting up the classpath, etc.

 * to extend the <code>runtimeTargetHandlers</code> extension point.

 * <b>Provisional API:</b> This class/interface is part of an interim API that is still under development and expected to
