# Script description:  Creates model definition files for WW3
#
# Author:   Jose-Henrique Alves Org: NCEP/EMC      Date: 2019-04-20
# Abstract: This script is the init config for the global multi_grid wave model.
#           It creates model definition files with all configurations of spatial
#           and spectral grids, as well as physics parameters and time steps.
