+# ![Boost.Utility](doc/logo.png)
+
+Boost.Utility, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), provides a number of smaller components, too small to be called libraries in their own right. See the documentation for the list of components.
+
+### Directories
+
+* **doc** - Documentation sources
+* **include** - Interface headers of Boost.Utility
+* **test** - Boost.Utility unit tests
+
+### More information
+
+* [Documentation](https://boost.org/libs/utility)
+* [Report bugs](https://github.com/boostorg/utility/issues/new). Be sure to mention Boost version, Boost.Utility component, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
+* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](https://www.boost.org/LICENSE_1_0.txt).
+
+### Build status
+
+Master: [![Travis CI](https://travis-ci.org/boostorg/utility.svg?branch=master)](https://travis-ci.org/boostorg/utility)
+Develop: [![Travis CI](https://travis-ci.org/boostorg/utility.svg?branch=develop)](https://travis-ci.org/boostorg/utility)

-  <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()

-<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.

-// 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
-// tests were to fail.

-			<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>
