Usage :
makegcm [options] -m arch exec
[-h]                       : help
[-prod / -dev / -debug]    : compilation en mode production (default) / developpement / debug .
 -arch nom_arch            : target architecture, use paths and compilation options from arch files arch/arch-NAME.*
 -arch_path PATH           : use arch files PATH/arch-ARCH.*
 -parallel mpi|mpi_omp     : pure MPI or hybrid MPI/OpenMP parallelism
 -job N                    : parallel compilation as with make -j N 
 -full                     : full compilation
 -with_xios                : use XIOS for I/O (default is NetCDF-CF on native grid)
 -no_io                    : disable I/O altogether
 -external_ioipsl PATH     : use IOIPSL from PATH rather than tools/ioipsl
 -physics lmdz_generic     : use LMDZ generic physics (planets)
 -external_physics         : allows external physics
 -mixed_prec               : compiles unstructured dynamics in single precision (float32)
