# This ebuild is created to handle building with both mpich2 and openmpi.
# However, without empi (in the science overlay), and some further
# conversion to use mpi.eclass, we can only handle one implementation
# at a time. I still believe it's better to have the ebuild setup
# correctly in preperation.
