It is freely available for download.</li> </ul> <p>You may write commercial, proprietary, or otherwise non-free software only if you have purchased one of the <a href="commercialeditions.html">commercial editions</tt></a>. If you purchase a commercial edition, you are entitled to technical support and upgrades on any supported platform.</p> <p>The 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> <p>Users of commercial editions can also take advantage of <i>Qt Designer</i>'s support for commercial IDEs.</p> <p /><address><hr /><div align="center"> <table width="100%" cellspacing="0" border="0"><tr class="address"> <td width="30%">Copyright © 2007 <a href="trolltech.html">Trolltech</a></td> <td width="40%" align="center"><a href="trademarks.html">Trademarks</a></td> <td width="30%" align="right"><div align="right">Qt Jambi </div></td> </tr></table></div></address></body> </html>
