-    <title>Description</title>
-
-    <para><command>apachectl</command> is a front end to the Apache HyperText
-    Transfer Protocol (HTTP) server. It is designed to help the
-    administrator control the functioning of the Apache
-    <command>httpd</command> daemon.</para>
-
-    <para>The <command>apachectl</command> script takes one-word arguments like
-    <option>start</option>,
-    <option>restart</option>, and
-    <option>stop</option>, and translates them
-    into appropriate signals to <command>httpd</command>.</para>
-
-    <para>The <command>apachectl</command> script returns a 0 exit value on
-    success, and &gt;0 if an error occurs.</para>

-      <title>Compatibility</title>
-
-      <para>The version of <command>apachectl</command> used on this
-      system is a replacement script intended to be mostly (but not
-      completely) compatible with version provided with
-      <emphasis>Apache httpd</emphasis>.  This
-      <command>apachectl</command> mostly acts as a wrapper around
-      <command>systemctl</command> and manipulates the
-      <command>systemd</command> service for <command>httpd</command>.
-      The interface to the <emphasis>Apache</emphasis> version of
-      <command>apachectl</command> is described at <ulink
-      url="https://httpd.apache.org/docs/2.4/programs/apachectl.html"/>.</para>

-      <para>The following differences are present in the version of
-      <command>apachectl</command> present on this system:
-
-      <itemizedlist>
-        <listitem><para>Option arguments passed when starting
-        <command>httpd</command> are not allowed.  These should be
-        configured in the systemd service directly (see <citerefentry><refentrytitle>httpd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>).</para></listitem>
-
-        <listitem><para>The <command>"fullstatus"</command> option is
-        not available.</para></listitem>
-
-        <listitem><para>The <command>"status"</command> option does

+    <p>By default, the server merges (or collapses) multiple consecutive slash
+       ('/') characters in the path component of the request URL.</p>
+
+    <p>When mapping URL's to the filesystem, these multiple slashes are not 
+       significant.  However, URL's handled other ways, such as by CGI or proxy,
+       might prefer to retain the significance of multiple consecutive slashes. 
+       In these cases <code class="directive">MergeSlashes</code> can be set to 
+       <em>OFF</em> to retain the multiple consecutive slashes.  In these
+       configurations, regular expressions used in the configuration file that match
+       the path component of the URL (<code class="directive">LocationMatch</code>,
+       <code class="directive">RewriteRule</code>, ...) need to take into account multiple 
+       consecutive slashes.</p>
