+       <h2><a name="introduction">Introduction</a></h2>
+       <p>
+               The <b>ini_file</b> classes are used to read and write INI files.
+               The format of an INI file is defined as follow:
+       </p>
+       <ul>
+               <li>Files are composed of comments, sections and parameters</li>
+               <li>Comments start with a semi-colon (;) at the very beginning
+                               of a line</li>
+               <li>Sections names are defined between square brackets ([ and ]) and
+                               start at the very beginning of a line</li>
+               <li>Parameters are defined as a name, followed by an equal sign
+                               followed by a value. There can be spaces before and after the
+                               equal sign. Spaces at the end of a value are also trimmed.</li>
+               <li>Empty lines are legal and skipped silently.</li>
+       </ul>
+       <p>
+               There is an example:
+       </p>
+<pre class="code">
+
+  <font color="blue">; INI file sample</font>
+  <font color="purple">[section1]</font>

+  <font color="green">var2 = value2</font>
+
+  <font color="purple">[section2]</font>
+  <font color="green">var3= value3</font>

+       <h2><a name="usage">Usage</a></h2>
+       <p>
+               An INI file is represented by a set of sections and one set of
+               parameters per section. Sets are defined as maps. Sections and
+               parameters have a name, a comment and parameters also have a
+               value. All of these objects are represented below:
+       </p>
+       <p>
+               <table align="center"><tbody><tr><td align="center">

+               <li>instantiating a <b>section_map</b> object;</li>
