-Boost StaticAssert Library
-============================
-
-The Boost StaticAssert library provides static assertions for C++, this library is the ancestor to C++ native static_assert's and 
-can be used on older compilers which don't have that feature.
-
-This library has been merged into [Boost.Config](https://github.com/boostorg/config). The full documentation is available on [boost.org](https://www.boost.org/doc/libs/release/libs/config).

+      <H3><A name="overview"></A>Overview</H3>
+      <P>The header &lt;boost/static_assert.hpp&gt; supplies a single macro 
+         BOOST_STATIC_ASSERT(x), which generates a compile time error message if the <a href="../../more/int_const_guidelines.htm">
+            integral-constant-expression</a> <i>x</i> is not true. In other words it is 
+         the compile time equivalent of the assert macro; this is sometimes known as a 
+         "compile-time-assertion", but will be called a "static assertion" throughout 
+         these docs. Note that if the condition is true, then the macro will generate 
+         neither code nor data - and the macro can also be used at either namespace, 
+         class or function scope. When used in a template, the static assertion will be 
+         evaluated at the time the template is instantiated; this is particularly useful 
+         for validating template parameters.
+      </P>
+      <p>One of the aims of BOOST_STATIC_ASSERT is to generate readable error messages. 
+         These immediately tell the user that a library is being used in a manner that 
+         is not supported. While error messages obviously differ from compiler to 
+         compiler, but you should see something like:
+      </p>
+      <pre>Illegal use of STATIC_ASSERTION_FAILURE&lt;false&gt;</pre>
+      <p>Which is intended to at least catch the eye!</p>
+      <p>You can use BOOST_STATIC_ASSERT at any place where you can place a declaration, 
+         that is at <a href="#class">class</a>, <a href="#function">function</a> or <a href="#namespace">
+            namespace</a> scope, this is illustrated by the following examples:</p>
+      <h3><a name="namespace"></a><A name="namespace"></A>Use at namespace scope.</h3>
+      <p>The macro can be used at namespace scope, if there is some requirement must 
+         always be true; generally this means some platform specific requirement. 
+         Suppose we require that <b>int</b> be at least a 32-bit integral type, and that <b>
+            wchar_t</b> be an unsigned type. We can verify this at compile time as 
+         follows:</p>
+      <pre>#include &lt;climits&gt;
+#include &lt;cwchar&gt;
+#include &lt;boost/static_assert.hpp&gt;
+
+namespace my_conditions {
+
+BOOST_STATIC_ASSERT(sizeof(int) * CHAR_BIT &gt;= 32);
+BOOST_STATIC_ASSERT(WCHAR_MIN &gt;= 0);
+
+} // namespace my_conditions
+</pre>
+      <p>The use of the namespace <i>my_conditions</i> here requires some comment. The 
+         macro BOOST_STATIC_ASSERT works by generating an <strong>typedef</strong> declaration, 
+         and since the typedef must have a name, the macro generates one automatically 
+         by mangling a stub name with the value of __LINE__. When BOOST_STATIC_ASSERT is 
+         used at either class or function scope then each use of BOOST_STATIC_ASSERT is 
+         guaranteed to produce a name unique to that scope (provided you only use the 
+         macro once on each line). However when used in a header at namespace scope, 
+         that namespace can be continued over multiple headers, each of which may have 
+         their own static assertions, and on the "same" lines, thereby generating 
+         duplicate declarations. In theory the compiler should silently ignore duplicate 
+         typedef declarations, however many do not do so (and even if they do they are 
+         entitled to emit warnings in such cases). To avoid potential problems, if you 
+         use BOOST_STATIC_ASSERT in a header and at namespace scope, then enclose them 
+         in a namespace unique to that header.</p>
+      <h3><a name="function"></a><A name="function"></A>Use at function scope</h3>
+      <p>The macro is typically used at function scope inside template functions, when 
+         the template arguments need checking. Imagine that we have an iterator-based 
+         algorithm that requires random access iterators. If the algorithm is 
+         instantiated with iterators that do not meet our requirements then an error 
+         will be generated eventually, but this may be nested deep inside several 
+         templates, making it hard for the user to determine what went wrong. One option 
+         is to add a static assertion at the top level of the template, in that case if 
+         the condition is not met, then an error will be generated in a way that makes 
+         it reasonably obvious to the user that the template is being misused.</p>
+      <pre>#include &lt;iterator&gt;
+#include &lt;boost/static_assert.hpp&gt;
+#include &lt;boost/type_traits.hpp&gt;
+
+template &lt;class RandomAccessIterator &gt;
+RandomAccessIterator foo(RandomAccessIterator from, RandomAccessIterator to)
+{
+   // this template can only be used with
+   // random access iterators...
+   typedef typename std::iterator_traits&lt; RandomAccessIterator &gt;::iterator_category cat;
+   BOOST_STATIC_ASSERT((boost::is_convertible&lt;cat, const std::random_access_iterator_tag&amp;&gt;::value));
+   //
+   // detail goes here...
+   return from;
+}</pre>
+      <p>A couple of footnotes are in order here: the extra set of parenthesis around 
+         the assert, is to prevent the comma inside the is_convertible template being 
+         interpreted by the preprocessor as a macro argument separator; the target type 
+         for is_convertible is a reference type, as some compilers have problems using 
+         is_convertible when the conversion is via a user defined constructor (in any 
+         case there is no guarantee that the iterator tag classes are 
+         copy-constructible).</p>
+      <h3><a name="class"></a><A name="class"></A>Use at class scope</h3>
+      <p>The macro is typically used inside classes that are templates. Suppose we have 
+         a template-class that requires an unsigned integral type with at least 16-bits 
+         of precision as a template argument, we can achieve this using something like 
+         this:</p>
+      <pre>#include &lt;climits&gt;

+      <h3><A name="templates"></A>Use in templates</h3>
+      <P>Normally static assertions when used inside a class or function template, will 
+         not be instantiated until the template in which it is used is 
+         instantiated.&nbsp; However, there is one potential problem to watch out for: 
+         if the static assertion is <EM>not</EM> dependent upon&nbsp;one or 
+         more&nbsp;template parameters, then the compiler is permitted to evaluate the 
+         static assertion at the point it is first seen, irrespective of whether the 
+         template is ever instantiated, for example:</P>
+      <PRE>template &lt;class T&gt;<BR>struct must_not_be_instantiated<BR>{<BR>   BOOST_STATIC_ASSERT(false);<BR><BR><BR><BR>};</PRE>
+      <P>Will produce a compiler error with some compilers (for example Intel 8.1 or gcc 
+         3.4), regardless of whether the template is ever instantiated.&nbsp; A 
+         workaround in cases like this is to force the assertion to be dependent upon a 
+         template parameter:</P>
+      <PRE>template &lt;class T&gt;<BR>struct must_not_be_instantiated<BR>{<BR>   BOOST_STATIC_ASSERT(sizeof(T) == 0); // will be triggered if this type is instantiated<BR><BR><BR><BR>};</PRE>
+      <H3><A name="how"></A>How it works</H3>
+      <p>BOOST_STATIC_ASSERT works as follows. There is class STATIC_ASSERTION_FAILURE 
+         which is defined as:</p>
+      <pre>namespace boost{
+
+template &lt;bool&gt; struct STATIC_ASSERTION_FAILURE;
+
+template &lt;&gt; struct STATIC_ASSERTION_FAILURE&lt;true&gt;{};
+
+}</pre>
+      <p>The key feature is that the error message triggered by the undefined expression 
+         sizeof(STATIC_ASSERTION_FAILURE&lt;0&gt;), tends to be consistent across a wide 
+         variety of compilers. The rest of the machinery of BOOST_STATIC_ASSERT is just 
+         a way to feed the sizeof expression into a typedef. The use of a macro here is 
+         somewhat ugly; however boost members have spent considerable effort trying to 
+         invent a static assert that avoided macros, all to no avail. The general 
+         conclusion was that the good of a static assert working at namespace, function, 
+         and class scope outweighed the ugliness of a macro.</p>
