#
# Makefile to compile and link C programs with MPI subroutines
#
# Version valid for Linux machines with MPICH
#
# "make" compiles and links the specified main programs and modules,
# using the specified libraries (if any), and produces the executables
#
# "make clean" removes all files generated by "make"
#
# Dependencies on included files are automatically taken care of
