./compile_nemo.sh [Options] 


Options: [ORCA1 / ORCA2 / ORCA025 ] Model resolution, choose only one. Default: ORCA2
         [OFFLINE] Compile Coupled NEMO-TOP in offline mode
         [-full] Full recompilation of all components. This option can be added to all other options.
         [-cleannemo] Full recompilation of NEMO component  only.
         [-debug / -dev / -prod] Level of optimization. One of these can be added to all other compile options. Default: -prod.


Example 1: Default compilation of ORCA_ICE_TOP
./compile_nemo.sh

Example 2: Compilation of TOP offline
./compile_nemo.sh OFFLINE

Example 3: Compilation of ORCA_ICE without passive tracers
./compile_nemo.sh  NOTOP -cleannemo


Example 4: Default resoltuion (LR) compiled in debug mode
./compile_nemo.sh -debug

Example 5: Default compilation with full recompilation of NEMO and XIOS. No clean is needed.
./compile_nemo.sh -full

Example 6: Full recompilation in debug mode
./compile_nemo.sh OFFLINE -debug -full
