-> 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"
-><title>My
- Title</title></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"
-><title></TT
-> element, and at least one
- <TT
-CLASS="LITERAL"
-><para></TT
->. There is a limit of five section
- levels in Docbook, but generally three should be sufficient for our
- purposes.</P

+ "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"><title>My Title</title></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"><title></tt> element, and at least
+ one <tt class="LITERAL"><para></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>
+
+ <table border="0">
+ <tbody>
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><para></para></i></span>, paragraph
+ delimiter. Most text needs to be within paragraph elements (there
+ are some exceptions).</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><emphasis></emphasis></i></span>, the
+ stylesheets make this italics.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><filename></filename></i></span>, files
+ and directories.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><command></command></i></span>, command
+ examples.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><literallayout></literallayout></i></span>,
+ like <tt class="LITERAL"><pre></tt>, more or less.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><itemizedlist></itemizedlist></i></span>,
+ list with bullets.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><listitem></listitem></i></span>, member
+ of the above.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><screen></screen></i></span>, screen
+ output, implies <tt class=
+ "LITERAL"><literallayout></tt>.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class="EMPHASIS"><ulink
+ url="example.com"></ulink></i></span>, like HTML
+ <tt class="LITERAL"><a></tt> tag.</td>
+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS"><quote></quote></i></span>, for, doh,
+ quoting text.</td>
+ </tr>
+ </tbody>

+
+ <p>It will be easier if everyone follows a similar writing style. This
+ just makes it easier to read what someone else has written if it is all
+ done in a similar fashion.</p>
+
+ <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"> <para><br>
+ Some text goes here.<br>
+ </para><br>
+ </p>Tags marking
+ individual words, or few words, should be in-line:
+
+ <p class="LITERALLAYOUT">
+ Just to <emphasis>emphasize</emphasis>, some text goes here.<br>
+
+ </p>
+ </li>
+
+ <li>
+ <p>Tags should be nested and step indented for block text like:
+ (except in-line tags)</p>
+
+ <p class="LITERALLAYOUT"> <para><br>
+ <itemizedlist><br>
+ <para><br>
+ <listitem><br>
+ Some text goes here in our list example.<br>
+
+ </listitem><br>
+ </para><br>
+ </itemizedlist><br>
+ </para><br>
+ </p>This makes it easier
+ to find the text amongst the tags ;-)
+ </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
+ <comment> element, or the <!-- --> style comment
+ familiar from HTML. (Note in Docbook v4.x <comment> is
+ replaced by <remark>.)</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 (<ulink>), and avoid
+ this mistake:</p>
+
+ <p>My favorite site is <ulink
+ url="http://example.com">here</ulink>.</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 <ulink
+ url="http://example.com">example.com</ulink>.</p>
+ </li>
+
+ <li>
+ <p>All documents should be spell checked occasionally. <span class=
+ "APPLICATION">aspell</span> can check SGML with the <tt class=
+ "LITERAL">-H</tt> option. (<span class="APPLICATION">ispell</span>
+ I think too.)</p>

+ <h2 class="SECT2"><a name="AEN208" id="AEN208">3.3. Privoxy Custom
+ Entities</a></h2>
+
+ <p><span class="APPLICATION">Privoxy</span> documentation is using a
+ number of customized <span class="QUOTE">"entities"</span> to
+ facilitate documentation maintenance.</p>
+
+ <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="emphasis"><i class=
+ "EMPHASIS">generic</i></span>. That is the purpose; so it can be used
+ in varying contexts without additional modifications.</p>
+
+ <p>We are also using what <span class="APPLICATION">Docbook</span>
+ calls <span class="QUOTE">"internal entities"</span>. These are like
+ variables in programming. Well, sort of. For instance, we have the
+ <tt class="LITERAL">p-version</tt> entity that contains the current
+ <span class="APPLICATION">Privoxy</span> version string. You are
+ strongly encouraged to use these where possible. Some of these
+ obviously require re-setting with each release (done by the Makefile).
+ A sampling of custom entities are listed below. See any of the main
+ docs for examples.</p>
+
+ <ul>
+ <li>
+ <p>Re- <span class="QUOTE">"boilerplate"</span> text entities are
+ defined like:</p>
+
+ <p><tt class="LITERAL"><!entity supported SYSTEM
+ "supported.sgml"></tt></p>
+
+ <p>In this example, the contents of the file, <tt class=
+ "FILENAME">supported.sgml</tt> is available for inclusion anywhere
+ in the doc. To make this happen, just reference the now defined
+ entity: <tt class="LITERAL">&supported;</tt> (starts with an
+ ampersand and ends with a semi-colon), and the contents will be
+ dumped into the finished doc at that point.</p>
+ </li>
+
+ <li>
+ <p>Commonly used <span class="QUOTE">"internal
+ entities"</span>:</p>
+
+ <table border="0">

+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
+ "EMPHASIS">p-status</i></span>: the project status, either

+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=

+ </tr>
+
+ <tr>
+ <td><span class="emphasis"><i class=
