<h2>Introduction</h2>
Doxygen is a documentation system for C, C++ and IDL. It can generate an 
on-line class browser (in HTML) and/or an off-line reference manual 
(in \f$\mbox{\LaTeX}\f$) from a set 
of documented source files. There is also support for generating 
man pages and for converting the generated output into 
Postscript, hyperlinked PDF or compressed HTML.
The documentation is extracted directly from the 
sources. Doxygen is developed on <a href="http://www.linux.org">Linux</a>, 
but it runs on most other UNIX flavors as well. 
An executable for Windows 9x/NT is also available.

Doxygen can also be configured to extract the code-structure from undocumented
source files. This can be very useful to quickly find your way in large
source distributions.

You can even `abuse' doxygen for creating normal documentation (as I did
for this manual).

This manual is divided into two parts, each of which is divided into several 
sections.

The first part forms a user manual:
<ul>
<li>Section \ref install discusses how to 
      <a href="http://www.stack.nl/~dimitri/doxygen/download.html">download</a>, compile and install
                     doxygen for your platform.
<li>Section \ref starting tells you how to generate your first piece of 
                     documentation quickly. 
<li>Section \ref docblocks demonstrates the various ways that code can
                 be documented.
<li>Section \ref formulas shows how to insert formulas in the documentation.
<li>Section \ref diagrams describes the diagrams and graphs that doxygen can generate.
<li>Section \ref preprocessing explains how doxygen deals with macro definitions.
<li>Section \ref faq gives answers to frequently asked questions. 
<li>Section \ref trouble tells you what to do when you have problems.
</ul>

The second part forms a reference manual:

<ul>
<li>Section \ref features presents an overview of what Doxygen can do.
<li>Section \ref history shows what has changed during the development 
                 of Doxygen and what still has to be done.
<li>Section \ref doxygen_usage shows how to use the \c doxygen program.
<li>Section \ref doxytag_usage shows how to use the \c doxytag program.
<li>Section \ref doxysearch_usage shows how to use the \c doxysearch program. 
<li>Section \ref installdox_usage shows how to use the \c installdox
                 script that is generated by Doxygen if you use tag files. 
<li>Section \ref output shows how to generate the various output formats
                 supported by Doxygen.
<li>Section \ref autolink shows how to put links to files, classes, 
                 and members in the documentation.
<li>Section \ref config shows how to fine-tune doxygen, so it 
              generates the documentation you want.
<li>Section \ref commands shows an overview of the special commands that can be 
              used within the documentation.
<li>Section \ref htmlcmds shows an overview of the HTML commands that
              can be used within the documentation.
<li>Section \ref langhowto explains how to add support for new
              output languages.
</ul>


<h2>Projects using doxygen</h2>

I have compiled a small 
\htmlonly
<a href="http://www.stack.nl/~dimitri/doxygen/projects.html">list of projects</a> 
that use doxygen
\endhtmlonly
\latexonly
list of projects that use doxygen (see {\tt http://www.stack.nl/$\sim$dimitri/doxygen/projects.html})
\endlatexonly
If you know other projects, let me know and I'll add them. 

<h2>Future work</h2>
Although doxygen is used successfully by a lot of people already, 
there is always room for improvement. Therefore, I have compiled a 
\htmlonly
<a href="http://www.stack.nl/~dimitri/doxygen/todo.html">todo/wish list</a>
\endhtmlonly 
\latexonly
todo/wish list (see {\tt http://www.stack.nl/$\sim$dimitri/doxygen/todo.html})
\endlatexonly
of possible and/or requested enhancements. 

<h2>Acknowledgements</h2>
\addindex acknowledgements
Thanks go to:
<ul>
\addindex Doc++
<li>Malte Z&ouml;ckler and Roland Wunderling, authors of DOC++.
    The first version of Doxygen borrowed some code of an old version of DOC++. 
    Although I have rewritten practically all code since then, DOC++ has still 
    given me a good start in writing Doxygen.
<li>All people at Troll Tech, for creating a beautiful GUI Toolkit
    (which is even useful for GUI-less applications like doxygen :-)
<li>My brother <a href="http://www.stack.nl/~fidget/index.html">Frank</a>
    for rendering the logos.
<li>Harm van der Heijden for adding HTML help support.
<li>Parker Waerchter for adding the RTF output generator.
<li>Joerg Baumann, for adding conditional documentation blocks, and
    PDF links.
<li>Matthias Andree for providing a .spec script for building rpms from the
    sources.
<li>Jens Breitenstein, Christophe Bordeaux, Samuel Hägglund, Xet Erixon, 
    Vlastimil Havran, Ahmed Also Faisal, Alessandro Falappa, Kenji Nagamatsu,
    Francisco Oltra Thennet, Olli Korhonen for providing translations into
    various languages.
