+overview = """\
+SizedControls is an addon library that attempts to simplify the creation of
+sizer-based layouts. It adds the following classes:
+
+<b>SizedPanel</b>
+
+This class automatically creates its own sizer (a vertical box sizer 
+by default) and automatically adds its children to the sizer. You can change the
+SizedPanel's sizer type by calling panel.SetSizerType("type", [args]), where valid types are
+"horizontal", "vertical", "form" (a 2-col flex grid sizer), and "grid". Args include
+"cols" and "rows" attributes for grids. This class also applies control borders
+that adhere to the native platform's Human Interface Guidelines (HIG) on Win, GTK and Mac.
+
+<b>SizedFrame and SizedDialog</b>
+
+These classes automatically setup a SizedPanel which
+is appropriately positioned and given appropriate borders in accordance with the
+platform's HIGs.
+
+Since controls are added to the parent's sizer upon creation, you don't need to
+use sizer.Add or even create sizers yourself. You just use SetSizerType() to 
+change the sizer you want to use, and control.SetSizerProps() to change the
+sizer properties of the control. So as a result, code that used to look like this:
+
+<table bgcolor="#EFEFEF"><tr><td><code>
+... wx.Dialog init code...
+
+panel = wx.Panel(self, -1)
+b1 = wx.Button(panel, -1)
+b2 = wx.Button(panel, -1)
+t1 = wx.TextCtrl(panel, -1)
+b3 = wx.Button(panel, -1)
+
+sizer = wx.BoxSizer(wx.HORIZONTAL)
+sizer.Add(b1, 0, wx.ALL, 6)
+sizer.Add(b2, 0, wx.ALL, 6)
+sizer.Add(t1, 0, wx.EXPAND | wx.ALL, 6)
+sizer.Add(b3, 0, wx.ALL, 6)
+panel.SetSizer(sizer)
+
+dlgSizer = wx.BoxSizer()
+dlgSizer.Add(panel, 1, wx.EXPAND)
+self.SetSizer(dlgSizer)
+self.SetAutoLayout(True)
+
+... rest of dialog ...</code>
+</td></tr></table>
+
+would now look like this:
+
+<table bgcolor="#EFEFEF"><tr><td><code>
+... wx.Dialog init code...
+
+panel = self.GetContentsPane()
+panel.SetSizerType("horizontal")
+
+b1 = wx.Button(panel, -1)
+b2 = wx.Button(panel, -1)
+
+t1 = wx.TextCtrl(panel, -1)
+t1.SetSizerProps(expand=True)
+
+b3 = wx.Button(panel, -1)
+
+... rest of dialog ...</code>
+</td></tr></table>
+and the latter example will adhere to HIG spacing guidelines on all platforms,
+unlike the former example.
+
+Please check the demos for more complete and sophisticated examples of SizedControls
+in action.
