     @class wxModule

     The module system is a very simple mechanism to allow applications (and parts
     of wxWidgets itself) to define initialization and cleanup functions that are
     automatically called on wxWidgets startup and exit.
 
     To define a new kind of module, derive a class from wxModule, override the
-    wxModule::OnInit and wxModule::OnExit
-    functions, and add the DECLARE_DYNAMIC_CLASS and IMPLEMENT_DYNAMIC_CLASS to
-    header and implementation files (which can be the same file). On
-    initialization, wxWidgets will find all classes derived from wxModule, create
-    an instance of each, and call each OnInit function. On exit, wxWidgets will
-    call the OnExit function for each module instance.
+    wxModule::OnInit and wxModule::OnExit functions, and add the

     Note that your module class does not have to be in a header file.

     @code
-    // A module to allow DDE initialization/cleanup
+        // A module to allow DDE initialization/cleanup
