	3	This demo shows how to embed an ActiveX control in a wxPython application, (Win32 only.)
	4	<p>
	5	The MakeActiveXClass function dynamically builds a new Class on the fly, that has the
	6	same signature and semantics as wxWindow. This means that when you call the function
	7	you get back a new class that you can use just like wxWindow, (set the size and position,
	8	use in a sizer, etc.) except its contents will be the COM control.
	9	<p>
	10	This demo embeds the Adobe Acrobat Reader, and gives you some buttons for opening a PDF
	11	file, changing pages, etc. that show how to call methods on the COM object. If you don't
	12	have Acrobat Reader 4.0 installed it won't work.
