+## Revision 1.390  2004/08/13 09:49:13  geraint
+## Only use one level of MTT_work to prevent MTT from repeatedly copying or creating the same files.
+##
 ## Revision 1.389  2004/08/13 01:32:03  geraint
 ## Use ibg.m by default for both Xfig and Dia models.
 ##
 ## Revision 1.388  2004/08/11 08:18:07  geraint
 ## Ignores diy make files if the file ${rep}_rep.make.ignore exists, thus allowing user-defined makefiles to use the default MTT rules for languages which they do not override. See odes_rep.make and odeso_rep.make for an example of its use.
