+// 14 02 01 Remove extra ';'. Also, fixed 10-parameter to make_tuple. (DG)
+// 10 02 01 Fixed "null_type" constructors.
+// Implemented comparison operators globally.
+// Hide element_type_ref and element_type_const_ref.
+// (DG).
+// 09 02 01 Extended to tuples of length 10. Changed comparison for
+// operator<()
+// to the same used by std::pair<>, added cnull_type() (GP)
+// 03 02 01 Initial Version from original tuple.hpp code by JJ. (DG)

+// defines traits classes for composite types:
+// is_array, is_pointer, is_reference, is_member_pointer, is_enum, is_union.
+//
+// Fixed is_pointer, is_reference, is_const, is_volatile, is_same,
+// is_member_pointer based on the Simulated Partial Specialization work
+// of Mat Marcus and Jesse Jones. See http://opensource.adobe.com or
+// http://groups.yahoo.com/group/boost/message/5441
+// Some workarounds in here use ideas suggested from "Generic<Programming>:
+// Mappings between Types and Values"
+// by Andrei Alexandrescu (see http://www.cuj.com/experts/1810/alexandr.html).
+// Fixes for is_array are based on a newgroup posting by Jonathan Lundquist.
+
+//
+// Revision History:
+// 21st March 2001:
+// Fixed is_enum so that it works with incomplete types.
