-		<h2><a name="motivation">Motivation</a></h2>
-		Sometimes a value must be converted to a literal text form, such as an <code>int</code>
-		represented as a <code>string</code>, or vice-versa, when a <code>string</code> 
-		is interpreted as an <code>int</code>. Such examples are common when converting 
-		between data types internal to a program and representation external to a 
-		program, such as windows and configuration files.
-		<p>
-		The standard C and C++ libraries offer a number of facilities for performing 
-		such conversions. However, they vary with their ease of use, extensibility, and 
-		safety.
-		<p>
-			For instance, there are a number of limitations with the family of standard C 
-			functions typified by <code>atoi</code>:
-			<ul type="square">
-				<li>
-					Conversion is supported in one direction only: from text to internal data type. 
-					Converting the other way using the C library requires either the inconvenience 
-					and compromised safety of the <code>sprintf</code> function, or the loss of 
-					portability associated with non-standard functions such as <code>itoa</code>.
-				</li>
-				<li>
-					The range of types supported is only a subset of the built-in numeric types, 
-					namely <code>int</code>, <code>long</code>, and <code>double</code>.
-				</li>
-				<li>
-					The range of types cannot be extended in a uniform manner. For instance, 
-					conversion from string representation to <code>complex</code> or <code>rational</code>.
-				</li>
-			</ul>
-			The standard C functions typified by <code>strtol</code> have the same basic 
-			limitations, but offer finer control over the conversion process. However, for 
-			the common case such control is often either not required or not used. The <code>scanf</code>
-		family of functions offer even greater control, but also lack safety and ease 
-		of use.
-		<p>
-			The standard C++ library offers <code>stringstream</code> for the kind of 
-			in-core formatting being discussed. It offers a great deal of control over the 
-			formatting and conversion of I/O to and from arbitrary types through text. 
-			However, for simple conversions direct use of <code>stringstream</code> can be 
-			either clumsy (with the introduction of extra local variables and the loss of 
-			infix-expression convenience) or obscure (where <code>stringstream</code>
-		objects are created as temporary objects in an expression). Facets provide a 
-		comprehensive concept and facility for controlling textual representation, but 
-		their perceived complexity and high entry level requires an extreme degree of 
-		involvement for simple conversions, and excludes all but a few programmers.
-		<p>
-			The <code>lexical_cast</code> function template offers a convenient and 
-			consistent form for supporting common conversions to and from arbitrary types 
-			when they are represented as text. The simplification it offers is in 
-			expression-level convenience for such conversions. For more involved 
-			conversions, such as where precision or formatting need tighter control than is 
-			offered by the default behavior of <code>lexical_cast</code>, the conventional <code>
-				stringstream</code> approach is recommended. Where the conversions are 
-			numeric to numeric, <code><a href="../numeric/conversion/doc/html/boost_numericconversion/improved_numeric_cast__.html">numeric_cast</a></code>
-			may offer more reasonable behavior than <code>lexical_cast</code>.
-		<p>
-			For a good discussion of the options and issues involved in string-based 
-			formatting, including comparison of <code>stringstream</code>, <code>lexical_cast</code>, 
-			and others, see Herb Sutter's article, <a href="http://www.gotw.ca/publications/mill19.htm">
-				<i>The String Formatters of Manor Farm</i></a>.

-			<h2><a name="examples">Examples</a></h2>
-			The following example treats command line arguments as a sequence of numeric 
-			data: <blockquote>
-				<pre>int main(int argc, char * argv[])
-{
-    using boost::lexical_cast;
-    using boost::bad_lexical_cast;
-
-    std::vector&lt;short&gt; args;
-
-    while(*++argv)
-    {
-        try
-        {
-            args.push_back(lexical_cast&lt;short&gt;(*argv));
-        }
-        catch(bad_lexical_cast &amp;)
-        {
-            args.push_back(0);
-        }
-    }
-    ...
-}
-</pre>
-			</blockquote>The following example uses numeric data in a string expression: <blockquote>
-				<pre>void log_message(const std::string &amp;);
-
-void log_errno(int yoko)
-{
-    log_message(&quot;Error &quot; + boost::lexical_cast&lt;std::string&gt;(yoko) + &quot;: &quot; + strerror(yoko));

-			<blockquote>
-				<pre>template&lt;typename Target, typename Source&gt;
-  Target lexical_cast(const Source&amp; arg);
-</pre>
-			</blockquote>Returns the result of streaming <code>arg</code> into a
-			standard library string-based stream and then out as a <code>Target</code> object.
-			Where <code>Target</code> is either <code>std::string</code>
-			or <code>std::wstring</code>, stream extraction takes the whole content
-			of the string, including spaces, rather than relying on the default
-			<code>operator&gt;&gt;</code> behavior.
-			If the conversion is unsuccessful, a <a href="#bad_lexical_cast">
-				<code>bad_lexical_cast</code></a> exception is thrown.
-		<p>
-			The requirements on the argument and result types are:
-			<ul type="square">
-				<li>
-					<code>Source</code> is <i>OutputStreamable</i>, meaning that an <code>operator&lt;&lt;</code>
-					is defined that takes a <code>std::ostream</code> or <code>std::wostream</code> object on the
-					left hand side and an instance of the argument type on the right.
-				</li>
-				<li>
-					<code>Target</code> is <i>InputStreamable</i>, meaning that an <code>operator&gt;&gt;</code>
-					is defined that takes a <code>std::istream</code> or <code>std::wistream</code> object on the left hand side 
-					and an instance of the result type on the right.
-				</li>
-				<li>
-					<code>Target</code> is <i>CopyConstructible</i> [20.1.3].
-				</li>
-				<li>
-					<code>Target</code> is <i>DefaultConstructible</i>, meaning that it is possible 
-					to <i>default-initialize</i> an object of that type [8.5, 20.1.4].
-				</li>
-			</ul>
-			The character type of the underlying stream is assumed to be <code>char</code> unless
-			either the <code>Source</code> or the <code>Target</code> requires wide-character
-			streaming, in which case the underlying stream uses <code>wchar_t</code>.
-			<code>Source</code> types that require wide-character streaming are <code>wchar_t</code>,
-			<code>wchar_t *</code>, and <code>std::wstring</code>. <code>Target</code> types that
-			require wide-character streaming are <code>wchar_t</code> and <code>std::wstring</code>.
-			<p>
-			Where a higher degree of control is required over conversions, <code>std::stringstream</code>
-			and <code>std::wstringstream</code> offer a more appropriate path. Where non-stream-based conversions are 
-			required, <code>lexical_cast</code>
-		is the wrong tool for the job and is not special-cased for such scenarios.

-<h2><a name="faq">Frequently Asked Questions</h2>
-    <p> Q: Why does <code>lexical_cast&lt;int8_t&gt;("127")</code> throw <code>bad_lexical_cast</code>?
-    <br> A: The type <code>int8_t</code> is a typedef to <code>char</code> or <code>signed char</code>.
-    Lexical conversion to these types is simply reading a byte from source but since the source has
-    more than one byte, the exception is thrown.
-    <p>Please use other integer types such as <code>int</code> or <code>short int</code>. If bounds checking
-    is important, you can also call <a href="../../libs/numeric/conversion/doc/html/boost_numericconversion/improved_numeric_cast__.html">numeric_cast</a>:
-
-<pre><a href="../../libs/numeric/conversion/doc/html/boost_numericconversion/improved_numeric_cast__.html">numeric_cast</a>&lt;int8_t&gt;(lexical_cast&lt;int&gt;("127"));</pre>
-
-    <p> Q: What does <code>lexical_cast&lt;std::string&gt;</code> of an <code>int8_t</code> or <code>uint8_t</code> not do what I expect?
-    <br> A: As above, note that <code>int8_t</code> and <code>uint8_t</code> are actually chars and are formatted as such.  To avoid this, cast to an integer type first:
-
-<pre>lexical_cast&lt;std::string&gt;(static_cast&lt;int&gt;(n));</pre>
-
-    <p> Q: The implementation always resets the <code>ios_base::skipws</code> flag of an underlying stream object. It breaks my <code>operator&gt;&gt;</code> that works only in presence of this flag. Can you remove code that resets the flag?
-    <br> A: May be in a future version. There is no requirement in <a href="#n1973">[N1973]</a> to reset the flag but remember that <a href="#n1973">[N1973]</a> is not yet accepted by the committee. By the way, it's a great opportunity to make your <code>operator&gt;&gt;</code> conform to the standard. Read a good C++ book, study <code>std::sentry</code> and <a href="../../libs/io/doc/ios_state.html">ios_state_saver</a>.

-  <li>Call-by-const reference for the parameters. This requires partial specialization

-    pass by value there.<br>
-  </li>
-  <li>The MSVC 6 support is deprecated, and will be removed in a future Boost 
-    version. </li>
-</ul>
-<h3>Earlier:</h3>
-	
-<ul type="square">
-  <li>The previous version of <code>lexical_cast</code> used the default stream 
-    precision for reading and writing floating-point numbers. For numerics that 
-    have a corresponding specialization of <code>std::numeric_limits</code>, the 
-    current version now chooses a precision to match. <br>
-  <li>The previous version of <code>lexical_cast</code> did not support conversion 
-    to or from any wide-character-based types. For compilers with full language 
-    and library support for wide characters, <code>lexical_cast</code> now supports 
-    conversions from <code>wchar_t</code>, <code>wchar_t *</code>, and <code>std::wstring</code> 
-    and to <code>wchar_t</code> and <code>std::wstring</code>. <br>
-  <li>The previous version of <code>lexical_cast</code> assumed that the conventional 
-    stream extractor operators were sufficient for reading values. However, string 
-    I/O is asymmetric, with the result that spaces play the role of I/O separators 
-    rather than string content. The current version fixes this error for <code>std::string</code> 
-    and, where supported, <code>std::wstring</code>: <code>lexical_cast&lt;std::string&gt;("Hello, 
-    World")</code> succeeds instead of failing with a <code>bad_lexical_cast</code> 
-    exception. <br>
-  <li>The previous version of <code>lexical_cast</code> allowed unsafe and meaningless 
-    conversions to pointers. The current version now throws a <code>bad_lexical_cast</code> 
-    for conversions to pointers: <code>lexical_cast&lt;char *&gt;("Goodbye, World")</code> 
-    now throws an exception instead of causing undefined behavior.
