          To customize existing targets, there are two options:
          - Customize only one target:
              - copy/paste the target into this file, *before* the
                <import> task.
              - customize it to your needs.
          - Customize the whole content of build.xml
              - copy/paste the content of the rules files (minus the top node)
                into this file, replacing the <import> task.
              - customize to your needs.
