# Script to compile and link MPI programs
# We'd like to just add a few libraries to the link line and an include
# directory to the compile line, but some systems that MPICH supports make
# that difficult because the compiler and the linker are different programs.
# Thus, this code tries to figure out which options go where, at least for
# things that are different between compile and link steps.
