## Revision 1.213  1999/09/02 23:24:40  peterg
## Now explicitly generates executable _ode2odes.out file
## Which takes command line arguments
##
## Revision 1.212  1999/08/18 06:20:32  peterg
## Put -u back again .....
##
## Revision 1.211  1999/08/17 04:10:38  peterg
## Removed the -u switch from cp - it doesnt work on non GNU cps
