-<p>This document illustrates example programs using wxPython. All the
-examples make use of the new wx package syntax introduced in wxPython
-2.4.1, which is a bit different than older examples you might come
-across.</p>

-<p>If something hits you on the head, don't run around screaming that the
-sky is falling. Instead, take a close look and see if it wasn't a
-"wx" prefix that hit you. Apparently, they're dropping off wxPython
-class names like flies dropping dead in the scorching heat of a
-summer's day.</p>
-<p>Yes, the world is changing, and even our little wxPython world must
-change with it. Then again, I'm not fond of pesky summertime flies,
-and I'm not too upset that the "wx" prefixes are going to bite the
-dust. I think it's for the best. But, being the kind, considerate
-person that I am, I decided to write this guide to make the wx
-namespace transition easier for everyone, even Chicken Little.</p>
-<div class="note">
-<p class="admonition-title">Note</p>
-<p>Say what?</p>
-<p>If you have no idea what I mean by the "wx namespace transition,"
-consider yourself lucky. You can simply use these examples to
-learn wxPython in its current state (beginning with wxPython
-version 2.4.1). All you need to know is that previous wxPython
-code used a slightly different syntax that some folks (including
-me) considered ugly. So we changed it. And that's when the sky
-starting falling...</p>
-<p>If you want more of the technical details, read the <a class="reference" href="wxPackage.html">wx package
-documentation</a>.</p>
-</div>
-<p>Rather than simply <strong>tell</strong> you that everything will be okay, I
-decided to <strong>show</strong> you that everything will be okay. To do that,
-I've created a bunch of example programs using the new wx package. I
-hope you like them.</p>

-<div class="section" id="basic-program-example">

-<p>It doesn't get much simpler than this. Every wxPython program needs
-an application and a frame. To encourage good coding habits, I've
-split them into separate modules. They don't do much, but they're a
-good starting point.</p>
-<p>I include a simple App class in the frame module because the PyWrap
-"wrapper" utility (<tt class="literal"><span class="pre">pywrap</span></tt>) only works with modules that contain an
-application class. So including a simple one in each of your frame
-modules allows you to use the PyWrap runtime wrapper and debug your
-frames independent of your full application.</p>
-<p>Here is the module (<tt class="literal"><span class="pre">frame.py</span></tt>) that defines the frame class:</p>
