+ * This class is for objects where you want to separate the code for
+ * some methods into separate classes. This is useful if you have a
+ * class with not-frequently-used methods that contain lots of code
+ * that you would like to avoid always parsing.
+ *
+ * The PEAR_Autoloader class provides autoloading and aggregation.
+ * The autoloading lets you set up in which classes the separated
+ * methods are found. Aggregation is the technique used to import new
+ * methods, an instance of each class providing separated methods is
+ * stored and called every time the aggregated method is called.
