     Linking
   
-	  The extension class mechanism was designed to be useful with
-	  dynamically linked extension modules.  Modules that implement
-	  extension classes do not have to be linked against an extension
-	  class library.  The macro 'PyExtensionClass_Export' imports the
-	  'ExtensionClass' module and uses objects imported from this module
-	  to initialize an extension class with necessary behavior.
