# The purpose of this script is to make compiling and linking MPI C++
# programs easier by automatically putting in many of the right
# compiler options.
#
# Credits:
#
# This shell script is based heavily on mpiCC from MPICH-1.0.12.
# MPICH-1.0.12 is the MPI implementation developed by Argonne (Bill
# Gropp and Rusty Lusk) and Mississippi State (Tony Skjellum and
# Nathan Doss).
