+//  Revision History
+//  04 May 05 Added operator class bool_testable.  (Sam Partington)
+//  21 Oct 02 Modified implementation of operators to allow compilers with a
+//            correct named return value optimization (NRVO) to produce optimal
+//            code.  (Daniel Frey)
+//  02 Dec 01 Bug fixed in random_access_iteratable.  (Helmut Zeisel)
+//  28 Sep 01 Factored out iterator operator groups.  (Daryle Walker)
+//  27 Aug 01 'left' form for non commutative operators added;
+//            additional classes for groups of related operators added;
+//            workaround for empty base class optimization
+//            bug of GCC 3.0 (Helmut Zeisel)
+//  25 Jun 01 output_iterator_helper changes: removed default template 
+//            parameters, added support for self-proxying, additional 
+//            documentation and tests (Aleksey Gurtovoy)
+//  29 May 01 Added operator classes for << and >>.  Added input and output
+//            iterator helper classes.  Added classes to connect equality and
+//            relational operators.  Added classes for groups of related
+//            operators.  Reimplemented example operator and iterator helper
+//            classes in terms of the new groups.  (Daryle Walker, with help
+//            from Alexy Gurtovoy)
+//  11 Feb 01 Fixed bugs in the iterator helpers which prevented explicitly
+//            supplied arguments from actually being used (Dave Abrahams)
+//  04 Jul 00 Fixed NO_OPERATORS_IN_NAMESPACE bugs, major cleanup and
+//            refactoring of compiler workarounds, additional documentation
+//            (Alexy Gurtovoy and Mark Rodgers with some help and prompting from
+//            Dave Abrahams) 
+//  28 Jun 00 General cleanup and integration of bugfixes from Mark Rodgers and
+//            Jeremy Siek (Dave Abrahams)
+//  20 Jun 00 Changes to accommodate Borland C++Builder 4 and Borland C++ 5.5
+//            (Mark Rodgers)
+//  20 Jun 00 Minor fixes to the prior revision (Aleksey Gurtovoy)
+//  10 Jun 00 Support for the base class chaining technique was added
+//            (Aleksey Gurtovoy). See documentation and the comments below 
+//            for the details. 
+//  12 Dec 99 Initial version with iterator operators (Jeremy Siek)
+//  18 Nov 99 Change name "divideable" to "dividable", remove unnecessary
+//            specializations of dividable, subtractable, modable (Ed Brey) 
+//  17 Nov 99 Add comments (Beman Dawes)
+//            Remove unnecessary specialization of operators<> (Ed Brey)
+//  15 Nov 99 Fix less_than_comparable<T,U> second operand type for first two
+//            operators.(Beman Dawes)
+//  12 Nov 99 Add operators templates (Ed Brey)
+//  11 Nov 99 Add single template parameter version for compilers without
+//            partial specialization (Beman Dawes)
+//  10 Nov 99 Initial version
+
+// 10 Jun 00:
+// An additional optional template parameter was added to most of 
+// operator templates to support the base class chaining technique (see 
+// documentation for the details). Unfortunately, a straightforward
+// implementation of this change would have broken compatibility with the
+// previous version of the library by making it impossible to use the same
+// template name (e.g. 'addable') for both the 1- and 2-argument versions of
+// an operator template. This implementation solves the backward-compatibility
+// issue at the cost of some simplicity.
+//
+// One of the complications is an existence of special auxiliary class template
+// 'is_chained_base<>' (see 'detail' namespace below), which is used
+// to determine whether its template parameter is a library's operator template
+// or not. You have to specialize 'is_chained_base<>' for each new 
+// operator template you add to the library.
+//
+// However, most of the non-trivial implementation details are hidden behind 
+// several local macros defined below, and as soon as you understand them,
+// you understand the whole library implementation.
