/**
 * The various {@link org.apache.commons.proxy2.ProxyFactory} implementations create {@link Serializable} proxies;
 * however it is not always possible or practical to serialize the complete structure of a given proxy object. The
 * intent of this package is to facilitate the "serialization proxy pattern" by means of the {@code readResolve()} and
 * {@code writeReplace} methods supported by Java's serialization mechanism. This would normally be problematic with
 * Commons Proxy because its proxies are generalized to expose only methods declared by superclasses (where applicable)
 * or proxied interfaces. Therefore we declare the following interfaces:
 * <ul>
 *   <li>{@link ReadResolve}</li>
 *   <li>{@link WriteReplace}</li>
 * </ul>
 *
 * Typically, you should define your proxy to include {@link WriteReplace} among its interfaces, and implement it to
 * return some object that implements {@link ReadResolve} (or simply declares the {@code Object readResolve()} method
 * in any scope, but using the interface brings compiler assistance).
 *
 * Hint: Your {@link ReadResolve#readResolve()} implementation will typically use serialized information to recreate an
 * equivalent proxy object, which probably implies some form of {@code static} access.
