 /**
- * @file Mippleton.hh
- * Related to singletons, a mippleton is an object which can be obtained
- * globally using a unique name.  Unlike singletons, there can be multiple
- * mippletons per class, each with a different name or identifier.  Mippletons
- * are create automatically when they are first requested (retained) and deleted
- * after the last interested code releases its hold on the object.
+ * @file Library.hh
+ * A library is a collection of named objects of the same type.  Libraries use
+ * reference counting to automagically delete objects which no longer have any
+ * interested code.
