/**
 * Export packages from the Visual Age for Java workspace.
 * The packages are specified similar to all other MatchingTasks.
 * Since the VA Workspace is not file based, this task is simulating
 * a directory hierarchy for the workspace:
 * The 'root' contains all project 'dir's, and the projects contain
 * their respective package 'dir's.
 * Example:
 * <blockquote>
 * <vajexport destdir="C:/builddir/source">
 *  <include name="/MyVAProject/org/foo/subsystem1/**" />
 *  <exclude name="/MyVAProject/org/foo/subsystem1/test/**"/>
 * </vajexport>
 * </blockquote>
 * exports all packages in the project MyVAProject which start with
 * 'org.foo.subsystem1' except of these starting with
 * 'org.foo.subsystem1.test'.
