## Revision 1.2.4.2  2002/09/10 23:24:19  geraint
## Rationalised local and global optimisations.
## Fixes presentation of locally optimised code (ode view).
## Much more elegant :-)
##
## Revision 1.2.4.1  2002/09/03 23:44:43  geraint
## adding global optimisation (-optg).
##
## Revision 1.2  2001/07/27 23:29:10  geraint
## Optimises only when requested (-opt).
##
## Revision 1.1  2000/12/28 12:24:03  peterg
## Put under RCS
##
## Revision 1.2  1996/08/25 10:11:32  peter
## Added END in output file.
## Error handling.
