<h4>The software</h2>
<p>
This document describes a <b>short summary</b> usage of iCalcreator, a <em>PHP</em> software implementation of standards rfc5545/rfc5546 (rfc2445/rfc2446) to manage iCal formatted files.
</p>
<p>
iCalcreator is a <em>PHP</em> class package managing iCal files, supporting (non-)<strong>calendar</strong>
systems and applications to process and communicate <strong>calendar</strong> information like
events, agendas, tasks, reports, totos and journaling information.
</p>
<p>
The iCalcreator package, built of a <strong>calendar</strong> class with support of a function class and helper functions, are <strong>calendar</strong>
component property oriented. Development environment is <em>PHP</em> version 5.x but coding is done
to meet 4.x backward compatibility and may work. Some functions requires <em>PHP</em> >= 5.2.0.
</p>
<p>
The iCalcreator main class, utility class and helper functions are included in the "iCalcreator.class.php" file.
</p>
<p>
More iCalcreator supplementary, usage and "howto" information will be found at kigkonsult.se iCalcreator
<a href="http://kigkonsult.se/test/index.php" title="kigkonsult.se iCalcreator implement and test examples" target="_blank">coding and test</a> pages.
A strong recommendation is to have the document
<a href="http://kigkonsult.se/iCalcreator/docs/using.html" title="iCalcreator user's Manual" target="_blank">user's manual</a>
open in parallel when exploiting the link.
