+## 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.
