// = DESCRIPTION
//    This is a test to verify and illustrate the use of the
//    <ACE_RB_Tree ACE_RB_Tree_Iterator> and
//    <ACE_RB_Tree_Reverse_Iterator> classes.  Two different key and
//    item types are used in order to demonstrate specialization of
//    the <ACE_Less_Than> comparison function object template: int
//    (for which the native < operator is sufficient), and const char
//    * (for which < operator semantics must be replaced by strcmp
//    semantics).  An RB tree for each of the four possible type
//    parameter permutations over int and const char * is constructed
//    and filled in, and the resulting order is checked via an
//    iterator over each.
