The files contained in the golden.jar have been harvested from many
different sources, some are hand-crafted invalid class files (odds directory),
or from random JDK builds.

Generally these files serve to ensure the integrity of the packer and 
unpacker by,
   * maximizing the test coverage.
   * exercising all the Bands in the pack200 specification.
   * testing the behavior of the packer with invalid classes.
   * testing the archive integrity, ordering and description (date, sizes,
      CRC etc.)

Build:
To rebuild this JAR follow these steps:
    1. unzip the golden.jar to some directory lets call it "example"
    2. now we can add any directories with files into example.
    3. run the script BUILDME.sh  as
       % sh BUILDME.sh example

Note: the BUILDME.sh is known to work on all Unix platforms as well as Windows
      using Cygwin.

The above will create two JAR files in the current directory,
example.jar and example-cls.jar, now the example.jar can be used as the
golden.jar.

To ensure the JAR has been built correctly use jar -tvf and compare the
results of the old jar and the newly built one, note that the compressed sizes
may differ, however the timestamps etc. should be consistent.

Test:
    Basic:
        % pack200 --repack test.jar golden.jar

    Advanced: inspection of band contents
       Create a pack.conf as follows:
       % cat pack.conf
       com.sun.java.util.jar.pack.dump.bands=true

       % pack200 --no-gzip --config-file=pack.conf \
           --verbose golden.jar.pack golden.jar

       This command will dump the Bands in a unique directory BD_XXXXXX,
       one can then inspect the directory to ensure all of the bands are being
       generated. Familiarity of the Pack200 specification is strongly
       suggested.
