# Script to generate Fortran 2003 wrappers for FFTW's MPI functions.  This
# is necessary because MPI provides no way to deal with C MPI_Comm handles
# from Fortran (where MPI_Comm == integer), but does provide a way to
# deal with Fortran MPI_Comm handles from C (via MPI_Comm_f2c).  So,
# every FFTW function that takes an MPI_Comm argument needs a wrapper
# function that takes a Fortran integer and converts it to MPI_Comm.
