-    "../../boost/cast.hpp">boost/cast.hpp</a></h1>
-
-    <h2><a name="Cast Functions">Cast Functions</a></h2>
-
-    <p>The header <a href="../../boost/cast.hpp">boost/cast.hpp</a> provides <code>
-    <a href="#Polymorphic_cast">polymorphic_cast</a> and</code> <a href=
-    "#Polymorphic_cast"><code>polymorphic_downcast</code></a> function templates designed to
-    complement the C++ built-in casts.</p>
-
-    <p>The program <a href="cast_test.cpp">cast_test.cpp</a> can be used to
-    verify these function templates work as expected.</p>
-
-    <h3><a name="Polymorphic_cast">Polymorphic casts</a></h3>
-
-    <p>Pointers to polymorphic objects (objects of classes which define at
-    least one virtual function) are sometimes downcast or crosscast.
-    Downcasting means casting from a base class to a derived class.
-    Crosscasting means casting across an inheritance hierarchy diagram, such
-    as from one base to the other in a <code>Y</code> diagram hierarchy.</p>
-
-    <p>Such casts can be done with old-style casts, but this approach is
-    never to be recommended. Old-style casts are sorely lacking in type
-    safety, suffer poor readability, and are difficult to locate with search
-    tools.</p>
-
-    <p>The C++ built-in <code>static_cast</code> can be used for efficiently
-    downcasting pointers to polymorphic objects, but provides no error
-    detection for the case where the pointer being cast actually points to
-    the wrong derived class. The <code>polymorphic_downcast</code> template retains
-    the efficiency of <code>static_cast</code> for non-debug compilations, but for
-    debug compilations adds safety via an assert() that a <code>dynamic_cast</code>
-    succeeds.</p>
-
-    <p>The C++ built-in <code>dynamic_cast</code> can be used for downcasts and
-    crosscasts of pointers to polymorphic objects, but error notification in
-    the form of a returned value of 0 is inconvenient to test, or worse yet,
-    easy to forget to test. The throwing form of <code>dynamic_cast</code>, which
-    works on references, can be used on pointers through the ugly expression
-    &amp;<code>dynamic_cast&lt;T&amp;&gt;(*p)</code>, which causes undefined
-    behavior if <code>p</code> is <code>0</code>. The <code>polymorphic_cast</code>
-    template performs a <code>dynamic_cast</code> on a pointer, and throws an
-    exception if the <code>dynamic_cast</code> returns 0.</p>
-
-    <p>A <code>polymorphic_downcast</code> should be used for
-    downcasts that you are certain should succeed.  Error checking is
-    only performed in translation units where <code>NDEBUG</code> is
-    not defined, via
-<pre>  assert( dynamic_cast&lt;Derived&gt;(x) == x )
-</pre> where <code>x</code> is the source pointer.  This approach
-    ensures that not only is a non-zero pointer returned, but also
-    that it is correct in the presence of multiple inheritance.
-    Attempts to crosscast using <code>polymorphic_downcast</code> will
-    fail to compile.
-    <b>Warning:</b> Because <code>polymorphic_downcast</code> uses assert(), it
-    violates the One Definition Rule (ODR) if NDEBUG is inconsistently
-    defined across translation units. [See ISO Std 3.2]
-</p><p>
-    For crosscasts, or when the success of a cast can only be known at
-    runtime, or when efficiency is not important,
-    <code>polymorphic_cast</code> is preferred. </p>
-
-    <p>The C++ built-in <code>dynamic_cast</code> must be used to cast references
-    rather than pointers. It is also the only cast that can be used to check
-    whether a given interface is supported; in that case a return of 0 isn't
-    an error condition.</p>
-
-    <h3>polymorphic_cast and polymorphic_downcast synopsis</h3>
-
-    <blockquote>
-<pre>namespace boost {
-
-template &lt;class Derived, class Base&gt;
-inline Derived polymorphic_cast(Base* x);
-// Throws: std::bad_cast if ( dynamic_cast&lt;Derived&gt;(x) == 0 )
-// Returns: dynamic_cast&lt;Derived&gt;(x)
-
-template &lt;class Derived, class Base&gt;
-inline Derived polymorphic_downcast(Base* x);
-// Effects: assert( dynamic_cast&lt;Derived&gt;(x) == x );
-// Returns: static_cast&lt;Derived&gt;(x)
-
-}
-</pre>
-    </blockquote>
-
-    <h3>polymorphic_downcast example</h3>
-
-    <blockquote>
-<pre>#include &lt;boost/cast.hpp&gt;
-...
-class Fruit { public: virtual ~Fruit(){}; ... };
-class Banana : public Fruit { ... };
-...
-void f( Fruit * fruit ) {
-// ... logic which leads us to believe it is a Banana
-  Banana * banana = boost::polymorphic_downcast&lt;Banana*&gt;(fruit);
-  ...
-</pre>
-    </blockquote>
-
-    <h3>History</h3>
-
-    <p><code>polymorphic_cast</code> was suggested by Bjarne Stroustrup in "The C++
-    Programming Language".<br>
-     <code>polymorphic_downcast</code> was contributed by <a href=
-    "http://www.boost.org/people/dave_abrahams.htm">Dave Abrahams</a>.<code><br>
-     An old
-     numeric_cast</code> that was contributed by <a href=
-    "http://www.boost.org/people/kevlin_henney.htm">Kevlin Henney</a> is now superseeded by the <a href="../numeric/conversion/doc/html/index.html">Boost Numeric Conversion Library</a></p>

+[section Description]
+
+The Conversion Library improves program safety and clarity by performing
+otherwise messy conversions. It includes cast-style function templates designed 
+to complement the C++ Standard's built-in casts.
+
+To reduce coupling, the Boost Conversion Library is supplied by several headers:
+
+# The [@boost:boost/polymorphic_cast.hpp boost/polymorphic_cast.hpp] header
+  provides [link polymorphic_cast `polymorphic_cast<>`] and
+  [link polymorphic_downcast `polymorphic_downcast<>`]
+  to perform safe casting between polymorphic types.
+# The [@boost:boost/polymorphic_pointer_cast.hpp boost/polymorphic_pointer_cast.hpp] header
+  provides [link polymorphic_pointer_cast `polymorphic_pointer_cast<>`] and
+  [link polymorphic_pointer_cast `polymorphic_pointer_downcast<>`]
+# The [@boost:boost/implicit_cast.hpp boost/implicit_cast.hpp] header provides `implicit_cast<>` 
+  to perform implicit casts only (no down-cast, no void*->T*, no U->T if T has only explicit constructors for U).
+
+[endsect]
+
+[section Polymorphic casts]
+Pointers to polymorphic objects (objects of classes which define at
+least one virtual function) are sometimes downcast or crosscast.
+Downcasting means casting from a base class to a derived class.
+Crosscasting means casting across an inheritance hierarchy diagram, such
+as from one base to the other in a [^Y] diagram hierarchy.
+
+Such casts can be done with old-style casts, but this approach is
+never to be recommended. Old-style casts are sorely lacking in type
+safety, suffer poor readability, and are difficult to locate with search
+tools.
+
+[#polymorphic_downcast]
+[section polymorphic_downcast]
+
+The C++ built-in `static_cast` can be used for efficiently
+downcasting pointers to polymorphic objects, but provides no error
+detection for the case where the pointer being cast actually points to
+the wrong derived class. The `polymorphic_downcast` template retains
+the efficiency of `static_cast` for non-debug compilations, but for
+debug compilations adds safety via an `assert()` that a `dynamic_cast`
+succeeds.
+
+A `polymorphic_downcast` should be used for
+downcasts that you are certain should succeed. Error checking is
+only performed in translation units where `NDEBUG` is
+not defined, via
+```
+    assert( dynamic_cast<Derived>(x) == x )
+```
+where `x` is the source pointer.  This approach
+ensures that not only is a non-zero pointer returned, but also
+that it is correct in the presence of multiple inheritance.
+Attempts to crosscast using `polymorphic_downcast` will
+fail to compile.
+
+[warning Because `polymorphic_downcast` uses `assert()`, it
+violates the One Definition Rule (ODR) if `NDEBUG` is inconsistently
+defined across translation units. See ISO Std 3.2]
+
+[h4 Example:]
+```
+    #include <boost/polymorphic_cast.hpp>
+    ...
+    class Fruit { public: virtual ~Fruit(){}; ... };
+    class Banana : public Fruit { ... };
+    ...
+    void f( Fruit * fruit ) {
+      // ... logic which leads us to believe it is a Banana
+      Banana * banana = boost::polymorphic_downcast<Banana*>(fruit);
+      ...
+    }
+```
+[endsect]
+
+[#polymorphic_cast]
+[section polymorphic_cast]
+
+The C++ built-in `dynamic_cast` can be used for downcasts and
+crosscasts of pointers to polymorphic objects, but error notification in
+the form of a returned value of 0 is inconvenient to test, or worse yet,
+easy to forget to test. The throwing form of `dynamic_cast`, which
+works on references, can be used on pointers through the ugly expression
+`&dynamic_cast<T&>(*p)`, which causes undefined
+behavior if `p` is `0`. The `polymorphic_cast`
+template performs a `dynamic_cast` on a pointer, and throws an
+exception if the `dynamic_cast` returns 0.
+
+For crosscasts, or when the success of a cast can only be known at runtime, 
+or when efficiency is not important, `polymorphic_cast` is preferred.
+
+The C++ built-in `dynamic_cast` must be used to cast references rather than pointers.
+It is also the only cast that can be used to check whether a given interface is supported; in that case a return of 0 isn't an error condition.
+
+[endsect]
+
+
+[#polymorphic_pointer_cast]
+[section polymorphic_pointer_cast]
+While `polymorphic_downcast` and `polymorphic_cast` work with built-in pointer types only,
+`polymorphic_pointer_downcast` and `polymorphic_pointer_cast` are more generic versions
+with support for any pointer type for which the following expressions would be valid:
+
+For `polymorphic_pointer_downcast`:
+```
+    static_pointer_cast<Derived>(p);
+    dynamic_pointer_cast<Derived>(p);
+```
+For `polymorphic_pointer_cast`:
+```
+    dynamic_pointer_cast<Derived>(p);
+    !p; // conversion to bool with negation
+```
+
+This includes C++ built-in pointers, `std::shared_ptr`,
+`boost::shared_ptr`, `boost::intrusive_ptr`, etc.
+
+
+[h4 Example:]
+```
+    #include <boost/polymorphic_pointer_cast.hpp>
+
+    class Fruit { public: virtual ~Fruit(){} };
+    class Banana : public Fruit {};
+
+    // Use one of these:
+    using FruitPtr = Fruit*;
+    using FruitPtr = std::shared_ptr<Fruit>;
+    using FruitPtr = boost::shared_ptr<Fruit>;
+    using FruitPtr = boost::intrusive_ptr<Fruit>;
+
+    void f(FruitPtr fruit) {
+      // ... logic which leads us to believe it is a banana
+      auto banana = boost::polymorphic_pointer_downcast<Banana>(fruit);
+      ...
+    }
+```
+

+[section History]
+`polymorphic_cast` was suggested by Bjarne Stroustrup in "The C++ Programming Language".
+
+`polymorphic_downcast` was contributed by [@http://www.boost.org/people/dave_abrahams.htm Dave Abrahams].
+
+`polymorphic_pointer_downcast` was contributed by [@http://www.boost.org/people/boris_rasin.htm Boris Rasin]
+and `polymorphic_pointer_cast` by Antony Polukhin.
+
+`polymorphic_downcast` overload for references was contributed by Julien Delacroix.
+
+An old `numeric_cast` that was contributed by [@http://www.boost.org/people/kevlin_henney.htm Kevlin Henney]
+is now superseded by the [@boost:numeric_conversion/doc/html/html/boost_numericconversion/improved_numeric_cast__.html Boost Numeric Conversion Library]

-Conversion Library</h1>
-
-<p>The Conversion Library improves program safety and clarity by performing
-otherwise messy conversions.&nbsp; It includes cast-style function templates designed to complement the C++
-Standard's built-in casts.</p>
-<p>To reduce coupling, particularly to standard library IOStreams, the Boost
-Conversion Library is
-supplied by several headers:</p>
-<ul>
-  <li>The <a href="cast.htm">boost/cast</a> header provides <b>polymorphic_cast&lt;&gt;</b>
-    and <b>polymorphic_downcast&lt;&gt;</b> to perform safe casting between
-  polymorphic types.<br>
-  </li>
-  <li>The <a href="../../doc/html/boost_lexical_cast.html">boost/lexical_cast</a> header provides <b>lexical_cast&lt;&gt;</b>
-    general literal text conversions, such as an <code>int</code> represented as
-    a <code>string</code>, or vice-versa.</li>
-</ul>
