 // === flext_base ==================================================
 
 /*! \brief Flext message only base object
+
+    This is the base class from which typical external object derive.
+    DSP objects should use the flext_dsp class which inherits from flext_base and
+    provides the needed functionality.
+
+    For a valid external object class you would also need FLEXT_HEADER, also if it's only
+    a base class without instantiated objects again.
+    To make an instance of an object class you would typically use FLEXT_NEW or 
+    its companions.
+
+    See the flext_obj class for additional information.

 /*! \brief Flext support class
+
 	A number of methods (most are static functions) are defined here for convenience.
 	This class doesn't define any data members, hence it can be inherited to all
 	classes (not only PD objects) to profit from the cross-platform functionality.
 	Examples are the overloaded memory allocation, atom and atom list functions,
 	thread functions and classes, the sample buffer class and others.
+
+    This class can also be used for a non-object class (not representing an external object)
+    and won't give any extra burden to it.
