Would anyone who intends to reply to that message ***PLEASE*** send a copy to us at Quintus as well? Anyone who has done this *should* have found it easy: the library contains lots of examples, such as library(setof), library(call), library(foreach), library(maplist), library(retract). It is probably easier to build on these (particularly library(call)) than to start from scratch.
