-          <a name="CONFOVERVIEW">6.2. Configuration Files Overview</a>
-        </h2>
-        <p>
-          For Unix, *BSD and Linux, all configuration files are located in
-          <tt class="FILENAME">/etc/privoxy/</tt> by default. For MS Windows,
-          OS/2, and AmigaOS these are all in the same directory as the <span
-          class="APPLICATION">Privoxy</span> executable. The name and number
-          of configuration files has changed from previous versions, and is
-          subject to change as development progresses.
-        </p>
-        <p>
-          The installed defaults provide a reasonable starting point, though
-          some settings may be aggressive by some standards. For the time
-          being, the principle configuration files are:
-        </p>
-        <p>
-        </p>
-        <ul>
-          <li>
-            <p>
-              The <a href="config.html">main configuration file</a> is named
-              <tt class="FILENAME">config</tt> on Linux, Unix, BSD, OS/2, and
-              AmigaOS and <tt class="FILENAME">config.txt</tt> on Windows.
-              This is a required file.
-            </p>
-          </li>
-          <li>
-            <p>
-              <tt class="FILENAME">match-all.action</tt> is used to define
-              which <span class="QUOTE">"actions"</span> relating to
-              banner-blocking, images, pop-ups, content modification, cookie
-              handling etc should be applied by default. It should be the
-              first actions file loaded.
-            </p>
-            <p>
-              <tt class="FILENAME">default.action</tt> defines many
-              exceptions (both positive and negative) from the default set of
-              actions that's configured in <tt class=
-              "FILENAME">match-all.action</tt>. It should be the second
-              actions file loaded and shouldn't be edited by the user.
-            </p>
-            <p>
-              Multiple actions files may be defined in <tt class=
-              "FILENAME">config</tt>. These are processed in the order they
-              are defined. Local customizations and locally preferred
-              exceptions to the default policies as defined in <tt class=
-              "FILENAME">match-all.action</tt> (which you will most probably
-              want to define sooner or later) are best applied in <tt class=
-              "FILENAME">user.action</tt>, where you can preserve them across
-              upgrades. The file isn't installed by all installers, but you
-              can easily create it yourself with a text editor.
-            </p>
-            <p>
-              There is also a web based editor that can be accessed from <a
-              href="http://config.privoxy.org/show-status" target=
-              "_top">http://config.privoxy.org/show-status</a> (Shortcut: <a
-              href="http://p.p/show-status" target=
-              "_top">http://p.p/show-status</a>) for the various actions
-              files.
-            </p>
-          </li>
-          <li>
-            <p>
-              <span class="QUOTE">"Filter files"</span> (the <a href=
-              "filter-file.html">filter file</a>) can be used to re-write the
-              raw page content, including viewable text as well as embedded
-              HTML and JavaScript, and whatever else lurks on any given web
-              page. The filtering jobs are only pre-defined here; whether to
-              apply them or not is up to the actions files. <tt class=
-              "FILENAME">default.filter</tt> includes various filters made
-              available for use by the developers. Some are much more
-              intrusive than others, and all should be used with caution. You
-              may define additional filter files in <tt class=
-              "FILENAME">config</tt> as you can with actions files. We
-              suggest <tt class="FILENAME">user.filter</tt> for any locally
-              defined filters or customizations.
-            </p>
-          </li>
-        </ul>
-
-        <p>
-          The syntax of the configuration and filter files may change between
-          different Privoxy versions, unfortunately some enhancements cost
-          backwards compatibility.
-        </p>
-        <p>
-          All files use the <span class="QUOTE">"<tt class=
-          "LITERAL">#</tt>"</span> character to denote a comment (the rest of
-          the line will be ignored) and understand line continuation through
-          placing a backslash ("<tt class="LITERAL">\</tt>") as the very last
-          character in a line. If the <tt class="LITERAL">#</tt> is preceded
-          by a backslash, it looses its special function. Placing a <tt
-          class="LITERAL">#</tt> in front of an otherwise valid configuration
-          line to prevent it from being interpreted is called "commenting
-          out" that line. Blank lines are ignored.
-        </p>
-        <p>
-          The actions files and filter files can use Perl style <a href=
-          "appendix.html#REGEX">regular expressions</a> for maximum
-          flexibility.
-        </p>
-        <p>
-          After making any changes, there is no need to restart <span class=
-          "APPLICATION">Privoxy</span> in order for the changes to take
-          effect. <span class="APPLICATION">Privoxy</span> detects such
-          changes automatically. Note, however, that it may take one or two
-          additional requests for the change to take effect. When changing
-          the listening address of <span class="APPLICATION">Privoxy</span>,
-          these <span class="QUOTE">"wake up"</span> requests must obviously
-          be sent to the <span class="emphasis"><i class=
-          "EMPHASIS">old</i></span> listening address.
-        </p>
-        <p>
-          While under development, the configuration content is subject to
-          change. The below documentation may not be accurate by the time you
-          read this. Also, what constitutes a <span class=
-          "QUOTE">"default"</span> setting, may change, so please check all
-          your configuration files on important issues.

+      Configuration Files Overview</a></h2>
+
+      <p>For Unix, *BSD and Linux, all configuration files are located in
+      <tt class="FILENAME">/etc/privoxy/</tt> by default. For MS Windows,
+      OS/2, and AmigaOS these are all in the same directory as the
+      <span class="APPLICATION">Privoxy</span> executable. The name and
+      number of configuration files has changed from previous versions, and
+      is subject to change as development progresses.</p>
+
+      <p>The installed defaults provide a reasonable starting point, though
+      some settings may be aggressive by some standards. For the time being,
+      the principle configuration files are:</p>
+
+      <ul>
+        <li>
+          <p>The <a href="config.html">main configuration file</a> is named
+          <tt class="FILENAME">config</tt> on Linux, Unix, BSD, OS/2, and
+          AmigaOS and <tt class="FILENAME">config.txt</tt> on Windows. This
+          is a required file.</p>
+        </li>
+
+        <li>
+          <p><tt class="FILENAME">match-all.action</tt> is used to define
+          which <span class="QUOTE">"actions"</span> relating to
+          banner-blocking, images, pop-ups, content modification, cookie
+          handling etc should be applied by default. It should be the first
+          actions file loaded.</p>
+
+          <p><tt class="FILENAME">default.action</tt> defines many exceptions
+          (both positive and negative) from the default set of actions that's
+          configured in <tt class="FILENAME">match-all.action</tt>. It should
+          be the second actions file loaded and shouldn't be edited by the
+          user.</p>
+
+          <p>Multiple actions files may be defined in <tt class=
+          "FILENAME">config</tt>. These are processed in the order they are
+          defined. Local customizations and locally preferred exceptions to
+          the default policies as defined in <tt class=
+          "FILENAME">match-all.action</tt> (which you will most probably want
+          to define sooner or later) are best applied in <tt class=
+          "FILENAME">user.action</tt>, where you can preserve them across
+          upgrades. The file isn't installed by all installers, but you can
+          easily create it yourself with a text editor.</p>
+
+          <p>There is also a web based editor that can be accessed from
+          <a href="http://config.privoxy.org/show-status" target=
+          "_top">http://config.privoxy.org/show-status</a> (Shortcut:
+          <a href="http://p.p/show-status" target=
+          "_top">http://p.p/show-status</a>) for the various actions
+          files.</p>
+        </li>
+
+        <li>
+          <p><span class="QUOTE">"Filter files"</span> (the <a href=
+          "filter-file.html">filter file</a>) can be used to re-write the raw
+          page content, including viewable text as well as embedded HTML and
+          JavaScript, and whatever else lurks on any given web page. The
+          filtering jobs are only pre-defined here; whether to apply them or
+          not is up to the actions files. <tt class=
+          "FILENAME">default.filter</tt> includes various filters made
+          available for use by the developers. Some are much more intrusive
+          than others, and all should be used with caution. You may define
+          additional filter files in <tt class="FILENAME">config</tt> as you
+          can with actions files. We suggest <tt class=
+          "FILENAME">user.filter</tt> for any locally defined filters or
+          customizations.</p>
+        </li>
+      </ul>
+
+      <p>The syntax of the configuration and filter files may change between
+      different Privoxy versions, unfortunately some enhancements cost
+      backwards compatibility.</p>
+
+      <p>All files use the <span class="QUOTE">"<tt class=
+      "LITERAL">#</tt>"</span> character to denote a comment (the rest of the
+      line will be ignored) and understand line continuation through placing
+      a backslash ("<tt class="LITERAL">\</tt>") as the very last character
+      in a line. If the <tt class="LITERAL">#</tt> is preceded by a
+      backslash, it looses its special function. Placing a <tt class=
+      "LITERAL">#</tt> in front of an otherwise valid configuration line to
+      prevent it from being interpreted is called "commenting out" that line.
+      Blank lines are ignored.</p>
+
+      <p>The actions files and filter files can use Perl style <a href=
+      "appendix.html#REGEX">regular expressions</a> for maximum
+      flexibility.</p>
+
+      <p>After making any changes, there is no need to restart <span class=
+      "APPLICATION">Privoxy</span> in order for the changes to take effect.
+      <span class="APPLICATION">Privoxy</span> detects such changes
+      automatically. Note, however, that it may take one or two additional
+      requests for the change to take effect. When changing the listening
+      address of <span class="APPLICATION">Privoxy</span>, these <span class=
+      "QUOTE">"wake up"</span> requests must obviously be sent to the
+      <span class="emphasis"><i class="EMPHASIS">old</i></span> listening
+      address.</p>
+
+      <p>While under development, the configuration content is subject to
+      change. The below documentation may not be accurate by the time you
+      read this. Also, what constitutes a <span class=
+      "QUOTE">"default"</span> setting, may change, so please check all your
+      configuration files on important issues.</p>
