<h1 align="center">About Qt<br /><small></small></h1>
<p>Qt by <a href="trolltech.html">Trolltech</tt></a> is the standard framework for developing high-performance cross-platform applications. Qt provides single-source portability across Microsoft Windows, Mac OS X, Linux, all major commercial Unix variants, and embedded Linux. On embedded Linux, the Qt API is available as Qtopia Core</tt>.</p>
<p>Qt provides application developers with all the functionality needed to build complex, high-performance GUI and console applications. Qt is fully object-oriented, easily extensible, and allows true component programming. Read the Whitepaper</tt> for a comprehensive technical overview.</p>
<p>Since its commercial introduction in early 1996, Qt has formed the basis of many thousands of successful applications worldwide, including Google Earth, Adobe Photoshop Elements, and Skype. Qt is also the basis of the popular <a href="http://www.kde.org/">KDE</tt></a> Linux desktop environment, a standard component of all major Linux distributions. See our Customer Success Stories</tt> for some examples of commercial Qt development.</p>
<p>Qt is supported on the following platforms:</p>
<ul>
<li><b>Microsoft Windows</b> -- 98, NT 4.0, ME, 2000, and XP</li>
<li><b>Unix/X11</b> -- Linux, Sun Solaris, HP-UX, HP Tru64 UNIX, IBM AIX, SGI IRIX and many others</li>
<li><b>Mac OS X</b> -- Mac OS X 10.3+</li>
<li><b>Embedded Linux</b> -- Linux platforms with framebuffer support</li>
</ul>
<p>See Trolltech's web site</tt> for the complete list of supported platform and compilers.</p>
<p>Qt is released in different editions:</p>
