+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,
+ 1. maximizing the test coverage.
+ 2. exercising all the Bands in the pack200 specification.
+ 2. testing the behavior of the packer with invalid classes.
+ 3. 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.
+ 2. 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:
+ 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 inspect the directory to ensure all of the bands are being
+ generated. Familiarity of the Pack200 specification is suggested.

+ * A kit of methods and classes useful for manipulating XML trees in
+ * memory. They are very compact and easy to use. An XML element
+ * occupies six pointers of overhead (like two arrays) plus a pointer
+ * for its name, each attribute name and value, and each sub-element.
+ * Many useful XML operations (or Lisp-like calls) can be accomplished
+ * with a single method call on an element itself.
+ * <p>
+ * There is strong integration with the Java collection classes.
+ * There are viewing and conversion operators to and from various
+ * collection types. Elements directly support list iterators.
+ * Most <tt>List</tt> methods work analogously on elements.
+ * <p>
+ * Because of implementation compromises, these XML trees are less
+ * functional than many standard XML classes.
+ * <ul>
+ * <li>There are no parent or sibling pointers in the tree.</li>
+ * <li>Attribute names are simple strings, with no namespaces.</li>
+ * <li>There is no internal support for schemas or validation.</li>
+ * </ul>
+ * <p>
+ * Here is a summary of functionality in <tt>XMLKit</tt>.
+ * (Overloaded groups of methods are summarized by marking some
+ * arguments optional with their default values. Some overloaded
+ * arguments are marked with their alternative types separated by
+ * a bar "|". Arguments or return values for which a null is
+ * specially significant are marked by an alternative "|null".
+ * Accessors which have corresponding setters are marked
