<h2>1. Commenting Styles</h2>
There are two different <i>styles</i> of commenting that doxygen recognises.
<p align="left">
Qt Style:<br>
<code>
/*!<br>
  .... text ....<br>
*/<br>
<br>
</code>
Qt Style Single line<br>
<code>
//! .... one line of text ....<br>
</code>
</p>

<p align="left">
JavaDoc Style:<br>
<code>
/**<br>
  * .... text ....<br>
  */<br>
</code>
<br>
JavaDoc Style Single line<br>
<code>
/// .... one line of text ....<br>
</code>
</p>

<p>
	Doxygen only allows one brief and one detailed description for each declaration/definition.
	If there is a brief description before a declaration, and one before the a definition, only
	the one before the <i>declaration</i> will be used. If the same situation occurs for a detailed
	description the one before the <i>definition</i> is preferred and the one before the declaration will
	be ignored.<br>
	A useful method is to have the brief documentation with the declaration in the header file,
	and the detailed documentation with the definition in the source file.
	<p>
		<i>Note: Standard C/C++ comments are ignored by doxygen, but will be included in the code listing
		for that file.	</i>
	</p>

<h2>2. Qt Style C++ Class Example</h2>
<p>
	Here is an example of a C++ class using Qt Style documentation.<br>
	The IEpair class from include/iepairs.h is used here. The html result of using these comments 
	can be found <a href="../example/index.html">here</a>.<br>
	<p>
		<i>Note: The resulting html was generated from a single file. If it were generated as part of
		the whole documentation, many of the function names and variables would be hyperlinks to
		their definitions.</i><br>
	</p>

<h2>4. Special Tags</h2>
<p>
	Special tags using the Qt style begin with a " \ ", or using JavaDoc style a " @ " (the two should not be mixed).<br>

<h2>5. Structural Tags</h2>
<p>
These are used to document a named object, and are not required to be located near that
object definition or declaration. This allows the documentation for an object to be located
anywhere in the doxygen input files. The exception to this rule however, is that these
documentation blocks cannot be within the body of a function or within C style comment blocks.
All structural commands are preceded by either a " \ " or a " @ ", depending on the 
documentation style, and require one or more parameters to specify the name of the object
the description is referring to.<br>
</p>
<p>
An example of the \file structural tag:
<pre>
/*! \file iepairs.h
    \brief One line documentation for this file
    \author Author(s)
    Long description of this file
*/
</pre>
</p>
