    To run the cs32 test on one cpu :
        ./testreport -t global_oce_cs32
    And to run the llc90 test on 24 cpus, using mpi
-      /testreport -of=../tools/build_options/linux_amd64_gfortran -MPI 24 -command 'mpirun -np TR_NPROC ./mitgcmuv' -t 'global_oce_cs32 global_oce_llc90'
+      ./testreport -of=../tools/build_options/linux_amd64_gfortran -MPI 24 -command 'mpirun -np TR_NPROC ./mitgcmuv' -t 'global_oce_cs32 global_oce_llc90'
    The optfile may be swaped for one that better suits your machine.

+Notes: - when using mpi and netcdf, testreport expects two environment variables :
+         export MPI_INC_DIR=/opt/local/include
+         export NETCDF_ROOT=/opt/local
+         or something similar depending on your computing environment
+       - whether with testreport or not mpi and netcdf libraries are a pre-requisite
 5) upon completion of the experiments, testreport should return something like
