/**
 * This annotation means the same thing as the <code>transient</code> keyword,
 * but it is ignored by all serialization systems other than GWT's. Usually the
 * <code>transient</code> keyword should be used in preference to this
 * annotation. However, for types used with multiple serialization systems, it
 * can be useful.
 * <p>
 * Note that GWT will actually accept any annotation named GwtTransient for this
 * purpose. This is done to allow libraries to support GWT serialization without
 * creating a direct dependency on the GWT distribution.
