+> All formal documents are maintained in Docbook SGML and located in the

+> directory. You will need
+ <A
+HREF="http://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.1</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. 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 that it is correct, then it should be hand
- copied to <tt class="FILENAME">config</tt>.</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 CVS. HTML versions are also being kept in CVS 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 CVS, 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</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 scp.</p>
- </li>
- </ol>
-
- <p>Finished docs should be occasionally submitted to CVS (<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 (this is done just prior to
- a new release).</p>

- <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"><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>
- </table>
-
- <p>Look at any of the existing docs for examples of all these and
- more.</p>
-
- <p>You might also find <span class="QUOTE">"<a href=

- <h2 class="SECT2"><a name="DOCSTYLE" id="DOCSTYLE">3.2. <span class=
- "APPLICATION">Privoxy</span> Documentation Style</a></h2>
-
- <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>
-

- entities"</span>:</p>
-
- <table border="0">

- </tr>
-

- <td><span class="emphasis"><i class=

+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
