# define_config.sh is called from the main compilation script compile_ipslcm7.sh
# The script will define which components to compile.
# By default all availble components are compiled.
#
# Step 1: The avaible components are defined. 
# Step 2: Define which components to compile. If argument [-subconfig subconfig] is set 
#         to the main compilation script, a control if the components needed are avaiable. 
#         If argument is subconfig is not set, the components defined in step 1 will be defined.


### Step 1: Check available components possible to compile
# LMDZ, ORCHIDEE and XIOS are considered mandatory and will not be checked.
