overview = """\
wx.SashLayoutWindow responds to OnCalculateLayout events generated by 
wxLayoutAlgorithm. It allows the application to use simple accessors to 
specify how the window should be laid out, rather than having to respond 
to events. The fact that the class derives from wx.SashWindow allows sashes 
to be used if required, to allow the windows to be user-resizable.

The documentation for wx.LayoutAlgorithm explains the purpose of this class 
in more detail.
