-//
-//     Iterator traits and policies for adapted iterators whose dereferenced

-//   template <class Incrementable> struct counting_iterator_generator;

-// Revision History
-// 14 Feb 2001  Removed unnecessary typedefs from counting_iterator_traits
-//              (Jeremy Siek)
-// 11 Feb 2001  Use BOOST_STATIC_CONSTANT (Dave Abrahams)
-// 11 Feb 2001  Clean up after John Maddocks's (finally effective!) Borland
-//              fixes (David Abrahams).
-// 10 Feb 2001  Use new iterator_adaptor<> interface (David Abrahams)
-// 10 Feb 2001  Rolled in supposed Borland fixes from John Maddock, but not
-//              seeing any improvement yet (David Abrahams)
-// 09 Feb 2001  Factored out is_numeric computation. Borland still
-//              unhappy :( (David Abrahams)
-// 08 Feb 2001  Beginning of a failed attempt to appease Borland
-//              (David Abrahams)
-// 07 Feb 2001  rename counting_iterator() -> make_counting_iterator()
-//              (David Abrahams)        
-// 04 Feb 2001  Added counting_iterator_generator; updated comments
-//              (David Abrahams)
-// 24 Jan 2001  initial revision, based on Jeremy Siek's
