  mpirun_options:
    -h      This help
    -machinefile <machine-file name>
        The file is a list of machines to be involved in the job run.
        Local machine is always involved (and hosts instance #0).
            Default machine file is /etc/gamma.conf
    -np <np>
            specify the number of process instances to be generated.
    -t      Testing - do not actually run, just print what would be
            executed
    -v      Verbose - throw in some comments

Multiple architectures as well as multiple pathnames for the executables
cannot be handled yet.

# Note that PWD may NOT be `pwd` if an explicit "cd", outside of the csh
# shell, is used.  A downside of this is that PWD may have a more reasonable

# if it is accessible from PWD and pwd; if so, we take the PWD value

# paths like /tmp_mnt/.... .  But if you try to open a file with that path,
# and the ACTUAL path has not been accessed before, the automounter fails
# to mount the partition.  In otherwords, the automounter is so mind-bogglingly
# stupid as to not recognize its OWN MOUNTS.  Network computing indeed.
#
# Note that PWD may ALSO be damaged, so we need to sed PWD as well...

# particular filename, since this will fail if the directory is not
