2MODULE oasis
3!
4! This module contains subroutines for initialization, sending and receiving
5! towards the coupler OASIS3. It also contains some parameters for the coupling.
6!
7! This module should always be compiled. With the coupler OASIS3 available the cpp key
8! CPP_COUPLE should be set and the entier of this file will then be compiled.
9! In a forced mode CPP_COUPLE should not be defined and the compilation ends before
10! the CONTAINS, without compiling the subroutines.
