  * Files are specified with an implicit fileset, using srcdir as a base directory.
  * The set of files to be included is specified with an includes attribute or
  * nested <includes> set. However, unlike a normal fileset, an empty includes attribute
  * means "no files" instead of "all files".  The Ant task also accepts "fork=true" and
  * classpath attribute or nested <classpath> element to run GenStubs in a separate VM
  * with the specified path. This is likely necessary if a JDK 7 parser is required to read the
  * JDK 7 input files.
