+ * @file   std_functors.i
+ * @date   Sun May  6 00:44:33 2007
+ * 
+ * @brief  This file provides unary and binary functors for STL
+ *         containers, that will invoke a Ruby proc or method to do
+ *         their operation.
+ *
+ *         You can use them in a swig file like:
+ *
+ *         %include <std_set.i>
+ *         %include <std_functors.i>
+ *
+ *         %template< IntSet > std::set< int, swig::BinaryPredicate<int> >;
+ *
+ *
+ *         which will then allow calling them from Ruby either like:
+ *  
+ *            # order of set is defined by C++ default
+ *            a = IntSet.new
+ *
+ *            # sort order defined by Ruby proc
+ *            b = IntSet.new( proc { |a,b| a > b } )
+ *
