#- Config name ---
# To add a new configuration called NAME you have to change this script
# 1. Add your configuration in LIST
# 2. Add the directories needed for this config : set -A DIR_NAME DIR1 DIR2 ...
# 3. Run fait_config NAME
# If there is no directory config/NAME/scripts, and in this no BB_make.ldef, 
# the config/ORCA2_LIM directory is copied under NAME
#
# Example 1 : in order to create a GYRE_TRC configuration :
# 1. In this script, change LIST to LIST="ORCA2_LIM \nGYRE \nGYRE_TRC"
# 2. In this script, add set -A DIR_GYRE_TRC OPA_SRC LIM_SRC_3 TOP_SRC C1D_SRC, take care of the syntax
# 3. Run fait_config GYRE_TRC
# Example 2 : in order to create an OFFLINE_TRC configuration :
# 1. In this script, change LIST to LIST="ORCA2_LIM \nGYRE \nOFFLINE_TRC"
# 2. In this script, add set -A DIR_OFFLINE_TRC OFF_SRC TOP_SRC, take care of the syntax
# 3. Run fait_config OFFLINE_TRC
# Example 2 : in order to use LIM3, just change LIM_SRC_2 in LIM_SRC_3
