overview = """\
A wx.SpinButton has two small up and down (or left and right) arrow buttons. 
It is often used next to a text control for increment and decrementing a value. 
Portable programs should try to use wx.SpinCtrl instead as wx.SpinButton is not 
implemented for all platforms (Win32 and GTK only currently).

NB: the range supported by this control (and wx.SpinCtrl) depends on the platform 
but is at least -0x8000 to 0x7fff. Under GTK and Win32 with sufficiently new version 
of comctrl32.dll (at least 4.71 is required, 5.80 is recommended) the full 32 bit 
range is supported.
