+The <b>wx.MimeTypesManager</b> class allows the application to retrieve the
+information about all known MIME types from a system-specific location and the
+filename extensions to the MIME types and vice versa. After initialization the
+methods <b>GetFileTypeFromMimeType()</b> and <b>GetFileTypeFromExtension()</b>
+may be called: they will return a <b>wx.FileType</b> object which may be further
+queried for file description, icon and other attributes.
+A global instance of <b>wx.MimeTypesManager</b> is always available as
+<b>wx.TheMimeTypesManager</b>. It is recommended to use this instance instead
+of creating your own because gathering MIME information may take quite a long
+on Unix systems.
+This demo shows how to use wx.TheMimeTypesManager to list all known MIME types
+and retrieve that information as a wx.FileType from either an extension or
+MIME type.
+For further information please consult the wxWindows documentation for
+<b>wx.MimeTypesManager</b> and <b>wx.FileType</b>.
