<p>Qt can be used to create both commercial and non-commercial software for a wide range of different deployment environments, and is supplied in a number of different forms to suit the needs of different kinds of developers.</p>
 
22
<p>In terms of license conditions, there are two main forms of Qt:</p>
 
23
<ul>
 
24
<li>The <a href="commercialedition.html">Qt Commercial Editions</a> are the commercial versions of <a href="aboutqt.html">Qt</a>.</li>
 
25
<li>The <a href="opensourceedition.html">Qt Open Source Edition</a> is the non-commercial version of Qt. It is freely available for download.</li>
 
26
</ul>
 
27
<p>You may write commercial, proprietary, or otherwise non-free software only if you have purchased one of the <a href="commercialedition.html">Commercial Editions</a>. If you purchase a Commercial Edition, you are entitled to technical support and upgrades on any supported platform.</p>
 
28
<p>Each Edition is available in a variety of different forms:</p>
 
29
<table align="center" cellpadding="2" cellspacing="1" border="0">
 
30
<tr valign="top" bgcolor="#a2c511"><th>Feature</th><th>Console</th><th>Desktop Light</th><th>Desktop</th></tr>
 
31
<tr valign="top" bgcolor="#f0f0f0"><td>Qt Core classes</td><td>X</td><td>X</td><td>X</td></tr>
 
32
<tr valign="top" bgcolor="#e0e0e0"><td>Qt GUI classes</td><td></td><td>X</td><td>X</td></tr>
 
33
<tr valign="top" bgcolor="#f0f0f0"><td>Networking</td><td>X</td><td></td><td>X</td></tr>
 
34

36
<tr valign="top" bgcolor="#e0e0e0"><td>XML</td><td>X</td><td></td><td>X</td></tr>
 
37
</table>
 
38
<p>The Commercial Desktop Edition also contains three database drivers (Oracle, IBM DB2, and Sybase), which are not included in the Open Source Edition because of license restrictions in the closed-source client libraries used to implement the drivers.</p>
 
39
<p>Users of Commercial Editions can also take advantage of <i>Qt Designer</i>'s support for commercial Integrated Development Environments.</p>
