-    <A

-     well. Especially some of the examples that are longer than 80 characters.
-     The build process for this file outputs to <TT
-CLASS="FILENAME"
->config.new</TT
->, 
-     which should be reviewed for errors and mis-formatting. Once satisfied

-> If you are not familiar with SGML, it is a markup language similar to HTML. 
- Actually, not a mark up language per se, but a language used to define 
- markup languages. In fact, HTML is an SGML application. Both will use
- <SPAN
-CLASS="QUOTE"
->"tags"</SPAN
-> to format text and other content. SGML tags can be much
- more varied, and flexible, but do much of the same kinds of things. The tags,
- or <SPAN
-CLASS="QUOTE"
->"elements"</SPAN
->, are definable in SGML. There is no set
- <SPAN
-CLASS="QUOTE"
->"standards"</SPAN
->. Since we are using
- <SPAN
-CLASS="APPLICATION"
->Docbook</SPAN
->, our tags are those that are defined by 
- <SPAN
-CLASS="APPLICATION"
->Docbook</SPAN
->. Much of how the finish document is
- rendered is determined by the <SPAN
-CLASS="QUOTE"

->.
- The stylesheets determine how each tag gets translated to HTML, or other
- formats.</P
-><P
-> Tags in Docbook SGML need to be always <SPAN
-CLASS="QUOTE"
->"closed"</SPAN
->. If not, you
- will likely generate errors. Example: <TT
-CLASS="LITERAL"
->&#60;title&#62;My
- Title&#60;/title&#62;</TT
->. They are also case-insensitive, but we
- strongly suggest using all lower case. This keeps compatibility with

->XML</SPAN
->.</P
-><P
-> Our documents use <SPAN
-CLASS="QUOTE"
->"sections"</SPAN
-> for the most part. Sections
- will be processed into HTML headers (e.g. <TT
-CLASS="LITERAL"
->h1</TT
-> for 
- <TT
-CLASS="LITERAL"
->sect1</TT
->). The <SPAN
-CLASS="APPLICATION"
->Docbook</SPAN

- <TT
-CLASS="LITERAL"
->&#60;para&#62;</TT

+    <p>All formal documents are maintained in Docbook SGML and located in the <samp class=
+    "COMPUTEROUTPUT">doc/source/*</samp> directory. You will need <a href="https://www.docbook.org/" target=
+    "_top">Docbook</a>, the Docbook DTD's and the Docbook modular stylesheets (or comparable alternatives), and either
+    <span class="APPLICATION">jade</span> or <span class="APPLICATION">openjade</span> (recommended) installed in order
+    to build docs from source. Currently there is <a href="../user-manual/index.html" target="_top"><i class=
+    "CITETITLE">user-manual</i></a>, <a href="../faq/index.html" target="_top"><i class="CITETITLE">FAQ</i></a>, and,
+    of course this, the <i class="CITETITLE">developer-manual</i> in this format. The <i class="CITETITLE">README</i>,
+    <i class="CITETITLE">AUTHORS</i>, <i class="CITETITLE">INSTALL</i>, <i class="CITETITLE">privoxy.8</i> (man page),
+    and <i class="CITETITLE">config</i> files are also now maintained as Docbook SGML. These files, when built, in the
+    top-level source directory are generated files! Also, the <span class="APPLICATION">Privoxy</span> <tt class=
+    "FILENAME">index.html</tt> (and a variation on this file, <tt class="FILENAME">privoxy-index.html</tt>, meant for
+    inclusion with doc packages), are maintained as SGML as well. <span class="emphasis"><i class="EMPHASIS">DO NOT
+    edit these directly</i></span>. Edit the SGML source, or contact someone involved in the documentation.</p>
+    <p><tt class="FILENAME">config</tt> requires some special handling. The reason it is maintained this way is so that
+    the extensive comments in the file mirror those in <i class="CITETITLE">user-manual</i>. But the conversion process
+    requires going from SGML to HTML to text to special formatting required for the embedded comments. Some of this
+    does not survive so well. Especially some of the examples that are longer than 80 characters.</p>
+    <p>Other, less formal documents (e.g. <tt class="FILENAME">LICENSE</tt>) are maintained as plain text files in the
+    top-level source directory.</p>
+    <p>Packagers are encouraged to include this documentation. For those without the ability to build the docs locally,
+    text versions of each are kept in Git. HTML versions are also being kept in Git under <tt class=
+    "FILENAME">doc/webserver/*</tt>.</p>
+    <p>Formal documents are built with the Makefile targets of <samp class="COMPUTEROUTPUT">make dok</samp>. The build
+    process uses the document SGML sources in <samp class="COMPUTEROUTPUT">doc/source/*/*</samp> to update all text
+    files in <samp class="COMPUTEROUTPUT">doc/text/</samp> and to update all HTML documents in <samp class=
+    "COMPUTEROUTPUT">doc/webserver/</samp>.</p>
+    <p>Documentation writers should please make sure documents build successfully before committing to Git, if
+    possible.</p>
+    <p>How do you update the webserver (i.e. the pages on privoxy.org)?</p>
+    <ol type="1">
+      <li>
+        <p>First, build the docs by running <samp class="COMPUTEROUTPUT">make dok dok-tidy</samp>.</p>
+      </li>
+      <li>
+        <p>Run <samp class="COMPUTEROUTPUT">make webserver</samp> which copies all files from <samp class=
+        "COMPUTEROUTPUT">doc/webserver</samp> to the sourceforge webserver via ssh.</p>
+      </li>
+    </ol>
+    <p>Finished docs should be occasionally submitted to Git (<tt class="FILENAME">doc/webserver/*/*.html</tt>) so that
+    those without the ability to build them locally, have access to them if needed. This is especially important just
+    prior to a new release! Please do this <span class="emphasis"><i class="EMPHASIS">after</i></span> the <tt class=
+    "LITERAL">$VERSION</tt> and other release specific data in <tt class="FILENAME">configure.in</tt> has been updated

+    <div class="SECT2">
+      <h2 class="SECT2"><a name="SGML" id="SGML">3.1. Quickstart to Docbook and SGML</a></h2>
+      <p>If you are not familiar with SGML, it is a markup language similar to HTML. Actually, not a mark up language
+      per se, but a language used to define markup languages. In fact, HTML is an SGML application. Both will use
+      <span class="QUOTE">"tags"</span> to format text and other content. SGML tags can be much more varied, and
+      flexible, but do much of the same kinds of things. The tags, or <span class="QUOTE">"elements"</span>, are
+      definable in SGML. There is no set <span class="QUOTE">"standards"</span>. Since we are using <span class=
+      "APPLICATION">Docbook</span>, our tags are those that are defined by <span class="APPLICATION">Docbook</span>.
+      Much of how the finish document is rendered is determined by the <span class="QUOTE">"stylesheets"</span>. The
+      stylesheets determine how each tag gets translated to HTML, or other formats.</p>
+      <p>Tags in Docbook SGML need to be always <span class="QUOTE">"closed"</span>. If not, you will likely generate
+      errors. Example: <tt class="LITERAL">&lt;title&gt;My Title&lt;/title&gt;</tt>. They are also case-insensitive,
+      but we strongly suggest using all lower case. This keeps compatibility with [Docbook] <span class=
+      "APPLICATION">XML</span>.</p>
+      <p>Our documents use <span class="QUOTE">"sections"</span> for the most part. Sections will be processed into
+      HTML headers (e.g. <tt class="LITERAL">h1</tt> for <tt class="LITERAL">sect1</tt>). The <span class=
+      "APPLICATION">Docbook</span> stylesheets will use these to also generate the Table of Contents for each doc. Our
+      TOC's are set to a depth of three. Meaning <tt class="LITERAL">sect1</tt>, <tt class="LITERAL">sect2</tt>, and
+      <tt class="LITERAL">sect3</tt> will have TOC entries, but <tt class="LITERAL">sect4</tt> will not. Each section
+      requires a <tt class="LITERAL">&lt;title&gt;</tt> element, and at least one <tt class=
+      "LITERAL">&lt;para&gt;</tt>. There is a limit of five section levels in Docbook, but generally three should be
+      sufficient for our purposes.</p>
+      <p>Some common elements that you likely will use:</p>

+      <p>It will be easier if everyone follows a similar writing style. This just makes it easier to read what someone

+      <p>Here it is:</p>
+      <ul>
+        <li>
+          <p>All tags should be lower case.</p>
+        </li>
+        <li>
+          <p>Tags delimiting a <span class="emphasis"><i class="EMPHASIS">block</i></span> of text (even small blocks)
+          should be on their own line. Like:</p>
+          <p class="LITERALLAYOUT">&nbsp;&lt;para&gt;<br>
+          &nbsp;&nbsp;Some&nbsp;text&nbsp;goes&nbsp;here.<br>
+          &nbsp;&lt;/para&gt;</p>
+          <p>Tags marking individual words, or few words, should be in-line:</p>
+          <p class="LITERALLAYOUT">
+          &nbsp;&nbsp;Just&nbsp;to&nbsp;&lt;emphasis&gt;emphasize&lt;/emphasis&gt;,&nbsp;some&nbsp;text&nbsp;goes&nbsp;here.</p>
+        </li>
+        <li>
+          <p>Tags should be nested and step indented for block text like: (except in-line tags)</p>
+          <p class="LITERALLAYOUT">&nbsp;&lt;para&gt;<br>
+          &nbsp;&nbsp;&lt;itemizedlist&gt;<br>
+          &nbsp;&nbsp;&nbsp;&lt;para&gt;<br>

+          &nbsp;&nbsp;&nbsp;&lt;/para&gt;<br>
+          &nbsp;&nbsp;&lt;/itemizedlist&gt;<br>
+          &nbsp;&lt;/para&gt;</p>
+          <p>This makes it easier to find the text amongst the tags ;-)</p>
+        </li>
+        <li>
+          <p>Use white space to separate logical divisions within a document, like between sections. Running everything
+          together consistently makes it harder to read and work on.</p>
+        </li>
+        <li>
+          <p>Do not hesitate to make comments. Comments can either use the &lt;comment&gt; element, or the &lt;!--
+          --&gt; style comment familiar from HTML. (Note in Docbook v4.x &lt;comment&gt; is replaced by
+          &lt;remark&gt;.)</p>
+        </li>
+        <li>
+          <p>We have an international audience. Refrain from slang, or English idiosyncrasies (too many to list :).
+          Humor also does not translate well sometimes.</p>
+        </li>
+        <li>
+          <p>Try to keep overall line lengths in source files to 80 characters or less for obvious reasons. This is not
+          always possible, with lengthy URLs for instance.</p>
+        </li>
+        <li>
+          <p>Our documents are available in differing formats. Right now, they are just plain text and/or HTML, but
+          others are always a future possibility. Be careful with URLs (&lt;ulink&gt;), and avoid this mistake:</p>
+          <p>My favorite site is &lt;ulink url="http://example.com"&gt;here&lt;/ulink&gt;.</p>
+          <p>This will render as <span class="QUOTE">"My favorite site is here"</span>, which is not real helpful in a
+          text doc. Better like this:</p>
+          <p>My favorite site is &lt;ulink url="http://example.com"&gt;example.com&lt;/ulink&gt;.</p>
+        </li>
+        <li>
+          <p>All documents should be spell checked occasionally. <span class="APPLICATION">aspell</span> can check SGML

+      <p>We are using a set of <span class="QUOTE">"boilerplate"</span> files with generic text, that is used by
+      multiple docs. This way we can write something once, and use it repeatedly without having to re-write the same
+      content over and over again. If editing such a file, keep in mind that it should be <span class=

+      <p>We are also using what <span class="APPLICATION">Docbook</span> calls <span class="QUOTE">"internal
