+    This is an example of how to use the Adobe Acrobat Reader ActiveX control to
+    read PDF files (requires Acrobat Reader 4 and up).
+    Controls like this are typically found and dumped from OLEVIEW.exe that is
+    distributed with Microsoft Visual C++.
+    This example also demonstrates how to create a backend for wxMediaCtrl.
