+/**
* Basic support for object serialization.
+ *
+ * The Serailizable interface is used to create checkpoints. Any
+ * object that implements this interface can be included in
+ * gem5's checkpointing system.
+ *
+ * Objects that support serialization should derive from this
+ * class. Such objects can largely be divided into two categories: 1)
+ * True SimObjects (deriving from SimObject), and 2) child objects
+ * (non-SimObjects).
+ *
+ * SimObjects are serialized automatically into their own sections
+ * automatically by the SimObject base class (see
+ * SimObject::serializeAll().
+ *
+ * SimObjects can contain other serializable objects that are not
+ * SimObjects. Much like normal serialized members are not serialized
+ * automatically, these objects will not be serialized automatically
+ * and it is expected that the objects owning such serializable
+ * objects call the required serialization/unserialization methods on
+ * child objects. The preferred method to serialize a child object is
+ * to call serializeSection() on the child, which serializes the
+ * object into a new subsection in the current section. Another option
+ * is to call serialize() directly, which serializes the object into
+ * the current section. The latter is not recommended as it can lead
+ * to naming clashes between objects.
+ *
+ * @note Many objects that support serialization need to be put in a
+ * consistent state when serialization takes place. We refer to the
+ * action of forcing an object into a consistent state as
+ * 'draining'. Objects that need draining inherit from Drainable. See
+ * Drainable for more information.
