+## Revision 1.399  2004/08/29 16:09:49  geraint
+## Added option -no-reduce
+##
+## Code sorting can now be used with Reduce (via sese.r) so that existing CRs
+## work with sorted code (using -make-sort or -sort), or without by using
+## -no-reduce; this option implies -make-sort.
+##
 ## Revision 1.398  2004/08/29 14:39:23  geraint
 ## Added rule to create dae from sorted equations (sese) if sorting is requested.
 ##
 ## Revision 1.397  2004/08/29 13:17:30  geraint
 ## Added rules to use sae (sorted algebraic equations) instead
