## Revision 1.12  1998/01/31 16:22:59  peterg
## Added IF MTTNx>0 THEN and IF MTTNy>0 THEN before the relevant
## assignements of MTTdX and MTTY to themselves.
##
## Revision 1.11  1997/09/18 09:45:08  peterg
## Canged the comment about linux reduce -- reduce reads this for some
## reason.
##
## Revision 1.10  1997/09/15 14:21:18  peterg
## Reads ese file twice to avoid a bug in Linux reduce !!!???
##
## Revision 1.9  1997/08/30 09:59:31  peterg
## Changed mehtod of writing out mtty to avoid a strange segmentation violation.
## Now uses MTTY := MTTY; approach.
##
## Revision 1.8  1997/04/23 09:31:20  peterg
## Now reads in the (top level) def file in the generated reduce code.
##
# Revision 1.7  1997/04/23  09:23:15  peterg
# Two argument version in preparation for heirarchical version
#
# Revision 1.6  1996/11/21  15:47:48  peterg
# Now inputs _params.r not _sympar.r
#
## Revision 1.5  1996/11/02 10:17:35  peterg
## Removed default constitutive relationship input.
##
# Revision 1.4  1996/09/12  12:10:05  peter
# Now reads the default constitutive relationship file.
#
## Revision 1.3  1996/08/25 09:43:26  peter
## General error handling.
##
## Revision 1.2  1996/08/25 08:31:28  peter
## Error handling added.
