 you may want to change that to
 "include BEKK.gfn"
 and check for functions beginning with "Get_": those have now a

Jack, do I understand correctly that there was for example a 
"Get_Loglik" function in MGARCH which has become "BEKK_GetLoglik" in
the 
new BEKK package? (And similar for the new BEKK_GetResids, 
BEKK_GetVariance, and BEKK_GetCovariance.)
thanks
