+<p>
+        This library may now be used in "standalone" mode without the rest
+        of the Boost C++ libraries, in order to do this you must either:
+      </p>
+<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
+<li class="listitem">
+            Have a C++17 compiler that supports <code class="computeroutput"><span class="identifier">__has_include</span></code>,
+            in this case if <code class="computeroutput"><span class="special">&lt;</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">config</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span></code> is <span class="bold"><strong>not</strong></span>
+            present then the library will automoatically enter standalone mode. Or:
+          </li>
+<li class="listitem">
+            Define BOOST_REGEX_STANDALONE when building.
+          </li>
+</ul></div>
+<p>
+        The main difference between the 2 modes, is that when Boost.Config is present
+        the library will automatically configure itself around various compiler defects.
+        In particular in order to use the library with exception support turned off,
+        you will either need a copy of Boost.Config in your include path, or else
+        manually define BOOST_NO_EXCEPTIONS when building.
