# This file sets the location of configure.nems and modules.nems.lua, and

# IMPORTANT: This file MUST NOT CONTAIN any logic specific to building
# FV3, CCPP, FMS, or NEMS.  Otherwise, coupled FV3 applications will
# break.  There should only be logic specific to the NEMSfv3gfs test
# system and NEMSfv3gfs file naming in this makefile fragment.

# Logic specific to FV3, CCPP, FMS, or NEMS belong in NEMS/src/incmake.
