+ * The metaclass <code>FreeArgsClass</code> provides classes with
+ * a facility of methods to accept unknown number of arguments.
+ * <p>
+ * For example, for the class:
+ * <pre>
+ * class MyCollection instantiates FreeArgsClass {
+ *     public generous add( Object[] arg ) { .. }
+ * }
+ * </pre>
+ * We can use the class above as follows:
+ * <pre>
+ * MyCollection collection = ..;
+ * collection.add( a, b, null, c, d );
+ * </pre>
+ * <p>
