  <!--
    This script is a starting point for creating a traditional
    "delta pack" for anyone who does not what to use p2 directly.
    
    The ant task has to be invoked via the antRunner application. Something 
    similar to 
      ./eclipse -application org.eclipse.ant.core.antRunner -f createdeltapack.xml
    
    Be sure to adjust, or pass in, the appropriate buildLabel and buildRepo.
    
    Note: the resulting delta pack has not been tested. 
    
    Please comment in bug 470913 with imrovements that can be made.
