To install RPL, uncompress and untar rpl.tar.Z. Then create a file "load-rpl.nsp" with the following lines in it: (in-package :NISP) (def-nisp-logical-name rpl (->pathname "/local/nisp/rpl")) (dsklap RPL/ run) Where "/local/nisp/rpl" is the directory where you put the RPL distribution. Loading "load-rpl" (using dsklap) will then load RPL. Sean P. Engelson Yale University
