## Revision 1.18  2000/08/24 17:11:40  peterg
## Now optimises as well as segmenting - uses the SCOPE package
##
## Revision 1.17  2000/05/20 15:23:56  peterg
## Paramererised version of sm etc etc (using -parameter switch)
##
## Revision 1.16  2000/04/18 11:14:18  peterg
## Put in the -parameters option
##
## Revision 1.15  2000/02/10 14:58:57  peterg
