+    //  Summary:
+    //  A semantic action policy that insert data into an associative 
+    //  container using a const reference to a key.
+    //  (This doc uses convention available in actors.hpp)
+    //
+    //  Actions (what it does):
+    //      ref.insert( T::value_type(key_ref,value) );
+    //      ref.insert( T::value_type(key_ref, T::mapped_type(first,last)));;
+    //      ref.insert( T::value_type(key_ref,value_ref) );
+    //
+    //  Policy name:
+    //      insert_at_action
+    //
+    //  Policy holder, corresponding helper method:
+    //      ref_const_ref_value_actor, insert_at_a( ref, key_ref ); 
+    //      ref_const_ref_const_ref_actor, insert_a( ref, key_ref, value_ref );
+    //
+    //  () operators: both
+    //
+    //  See also ref_const_ref_value_actor and ref_const_ref_const_ref_actor 
+    //  for more details.
