-    The main application class.  Derive from this and implement an OnInit
-    method that creates a frame and then calls self.SetTopWindow(frame)
+    The ``wx.App`` class represents the application and is used to:
+
+      * bootstrap the wxPython system and initialize the underlying
+        gui toolkit
+      * set and get application-wide properties
+      * implement the windowing system main message or event loop,
+        and to dispatch events to window instances
+      * etc.
+
+    Every application must have a ``wx.App`` instance, and all
+    creation of UI objects should be delayed until after the
+    ``wx.App`` object has been created in order to ensure that the gui
+    platform and wxWidgets have been fully initialized.
+
+    Normally you would derive from this class and implement an
+    ``OnInit`` method that creates a frame and then calls
+    ``self.SetTopWindow(frame)``.
