-  <h1>Generator Iterator Adaptor</h1>
-
-  <p>Defined in header <a href=
-  "../../boost/generator_iterator.hpp">boost/generator_iterator.hpp</a></p>
-
-  <p>The generator iterator adaptor makes it easier to create custom input
-  iterators from 0-ary functions and function objects. The adaptor takes a
-  <a href="http://www.sgi.com/tech/stl/Generator.html">Generator</a> and
-  creates a model of <a href=
-  "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>. Each
-  increment retrieves an item from the generator and makes it available to be
-  retrieved by dereferencing. The motivation for this iterator is that some
-  concepts can be more naturally expressed as a generator, while most STL
-  algorithms expect an iterator. An example is the <a href=
-  "../random/index.html">Random Number</a> library.</p>
-
-  <h2>Synopsis</h2>
-
-  <blockquote>
-    <pre>
-namespace boost {
-  template &lt;class Generator&gt;
-  class generator_iterator_policies;
-
-  template &lt;class Generator&gt;
-  class generator_iterator_generator;
-
-  template &lt;class Generator&gt;
-  typename generator_iterator_generator&lt;Generator&gt;::type
-  make_generator_iterator(Generator &amp; gen);
-}
-</pre>
-  </blockquote>
-  <hr>
-
-  <h2>The Generator Iterator Generator Class</h2>
-
-  <p>The class generator_iterator_generator is a helper class whose purpose
-  is to construct a generator iterator type. The template parameter for this
-  class is the Generator function object type that is being wrapped. The
-  generator iterator adaptor only holds a reference (or pointer) to the
-  function object, therefore the function object must outlive the generator
-  iterator adaptor constructed from it.</p>
-  <pre>
-template &lt;class Generator&gt;
-class generator_iterator_generator
-{
-public:
-  typedef <i>unspecified</i> type; // the resulting generator iterator type 
-}
-</pre>
-
-  <h3>Template Parameters</h3>
-
-  <table border summary="">
-    <tr>
-      <th>Parameter</th>
-
-      <th>Description</th>
-    </tr>
-
-    <tr>
-      <td><tt><a href=
-      "http://www.sgi.com/tech/stl/Generator.html">Generator</a></tt></td>
-
-      <td>The generator (0-ary function object) type being wrapped. The
-      return type of the function must be defined as
-      <tt>Generator::result_type</tt>. The function object must be a model of
-      <a href=
-      "http://www.sgi.com/tech/stl/Generator.html">Generator</a>.</td>
-    </tr>
-  </table>
-
-  <h3>Concept Model</h3>
-
-  <p>The generator iterator class is a model of <a href=
-  "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>.</p>
-
-  <h3>Members</h3>
-
-  <p>The generator iterator implements the member functions and operators
-  required of the <a href=
-  "http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>
-  concept.<br></p>
-  <hr>
-
-  <h2><a name="make_generator_iterator" id="make_generator_iterator">The
-  Generator Iterator Object Generator</a></h2>
-
-  <p>The <tt>make_generator_iterator()</tt> function provides a convenient
-  way to create generator iterator objects. The function saves the user the
-  trouble of explicitly writing out the iterator types.</p>
-
-  <blockquote>
-    <pre>
-template &lt;class Generator&gt;
-typename generator_iterator_generator&lt;Generator&gt;::type
-make_generator_iterator(Generator &amp; gen);
-</pre>
-  </blockquote>
-  <hr>
-
-  <h3>Example</h3>
-
-  <p>The following program shows how <code>generator_iterator</code>
-  transforms a generator into an input iterator.</p>
-
-  <blockquote>
-    <pre>
-#include &lt;iostream&gt;
-#include &lt;boost/generator_iterator.hpp&gt;
-
-class my_generator
-{
-public:
-  typedef int result_type;
-  my_generator() : state(0) { }
-  int operator()() { return ++state; }
-private:
-  int state;
-};
-
-int main()
-{
-  my_generator gen;
-  boost::generator_iterator_generator&lt;my_generator&gt;::type it = boost::make_generator_iterator(gen);
-  for(int i = 0; i &lt; 10; ++i, ++it)
-    std::cout &lt;&lt; *it &lt;&lt; std::endl;

+//  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;

+//  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.

-<h1>Shared Container Iterator</h1>
-
-Defined in header
-<a href="../../boost/shared_container_iterator.hpp">boost/shared_container_iterator.hpp</a>
-
-<p>
-The purpose of the shared container iterator is to attach the lifetime
-of a container to the lifetime of its iterators. In other words, the
-container will not be deleted until after all its iterators are
-destroyed.  The shared container iterator is typically used to
-implement functions that return iterators over a range of objects that
-only need to exist for the lifetime of the iterators.  By returning a
-pair of shared iterators from a function, the callee can return a
-heap-allocated range of objects whose lifetime is automatically managed.
-<p>
-The shared container iterator augments an iterator over a shared
-container.  It maintains a reference count on the shared 
-container. If only shared container iterators hold references to
-the container, the container's lifetime will end when the last shared
-container iterator over it is destroyed.  In any case, the shared
-container is guaranteed to persist beyond the lifetime of all
-the iterators. In all other ways, the
-shared container iterator behaves the same as its base iterator.

-The class template <tt>shared_container_iterator</tt> 
-is the shared container iterator type.  The <tt>Container</tt> template
-type argument must model the
-<a href="http://www.sgi.com/tech/stl/Container.html">Container</a>
-concept.
-
-<h3>Example</h3>
-
-<p>
-The following example illustrates how to create an iterator that 
-regulates the lifetime of a reference counted <tt>std::vector</tt>.
-Though the original shared pointer <tt>ints</tt> ceases to exist
-after <tt>set_range()</tt> returns, the
-<tt>shared_counter_iterator</tt> objects maintain references to the
-      underlying vector and thereby extend the container's lifetime.

-
-<h3>Model of</h3>
-
-The <tt>shared_container_iterator<Container></tt> type models the

-    (<tt>Container::iterator</tt>).
-
-<h3>Members</h3>
-
-The shared container iterator type implements the member functions and
-operators required of the <a

-concept, though only operations defined for the base iterator will be valid.
-In addition it has the following constructor:

-// next() and prior() are replacements for operator+ and operator- for
-// non-random-access iterators. The semantics of these operators are
-// such that after executing j = i + n, std::distance(i, j) equals
-// n. Tests are provided to ensure next() has the same
-// result. Parallel tests are provided for prior(). The tests call
-// next() and prior() several times. next() and prior() are very
-// simple functions, though, and it would be very strange if these

 		<h2>
-			<a name="functions_next_prior">Function</a> templates next() and prior()</h2>
-		<p>Certain data types, such as the C++ Standard Library's forward and bidirectional 
-			iterators, do not provide addition and subtraction via operator+() or 
-			operator-().&nbsp; This means that non-modifying computation of the next or 
-			prior value requires a temporary, even though operator++() or operator--() is 
-			provided.&nbsp; It also means that writing code like <code>itr+1</code> inside 
-			a template restricts the iterator category to random access iterators.</p>
-		<p>The next() and prior() functions provide a simple way around these problems:</p>
-		<blockquote>
-			<pre>template &lt;class T&gt;
-T next(T x) { return ++x; }
-
-template &lt;class T, class Distance&gt;
-T next(T x, Distance n)
-{
-    std::advance(x, n);
-    return x;
-}
-
-template &lt;class T&gt;
-T prior(T x) { return --x; }
-
-template &lt;class T, class Distance&gt;
-T prior(T x, Distance n)
-{
-    std::advance(x, -n);
-    return x;
-}</pre>
-		</blockquote>
-		<p>Usage is simple:</p>
-		<blockquote>
-			<pre>const std::list&lt;T&gt;::iterator p = get_some_iterator();
-const std::list&lt;T&gt;::iterator prev = boost::prior(p);
-const std::list&lt;T&gt;::iterator next = boost::next(prev, 2);</pre>
-		</blockquote>
-                <p>The distance from the given iterator should be supplied as an absolute value. For
-			example, the iterator four iterators prior to the given iterator <code>p</code>
-			may be obtained by <code>prior(p, 4)</code>.</p>
