     in contrast to other smalltalks, ST/X does not keep the
     method <-> category associations in the class (as organization),
     but instead keeps the category as an instance variable of method.
-    This may change in future versions.
 
     For compatibility with (fileOut-) files which include a class organization
-    message, aClass organization returns an instance of this class, which
+    message, 'aClass organization' returns an instance of this class, which
     implements the category change functionality.
+    Also, some PD code seems to use & define methods for ClassOrganizers - having this
+    (somewhat dummy) around helps to fileIn that code.
+
+    Notice, that instances of ClassOrganizer are not used in the current ST/X
+    system; all is pure mimicri.
+    This may change in future versions.
