RELATIONS-OF
============

syntax: (relations-of <frame-specifier>
                      {[:PART T | NIL | Var]
                       [:GENERAL T | NIL | Var]}+
                      [:DIRECT T | NIL | Var]
                      [:KB <kb>])

Warning: :PART and :GENERAL may both be set at a time.
         The key :KB is unsupported yet!
         :PART and :DIRECT are under construction!

This function returns the names of all characteristics
and/or parts of a frame as a list. If you only want  
the characteristics of a frame, then you have to set
':GENERAL' to T. If you only want the parts of a frame, 
then you have to set ':PART' to T. If you set ':DIRECT' 
to T you only get all directly specified characteris-
tics and/or parts of a frame.

example: >(relations-of 'capitalcity :direct T)
         (SEAT-OF-GOVERNMENT)
         >(relations-of 'capitalcity 
                        :general T :part T)
         (COUNTRY CLIMATE LANDSCAPE 
                 OFFER SEAT-OF-GOVERNMENT)
