! This module contains the interface between the LMDZ dynamics dyn3dmem module and XIOS.
! 
! Lists of subroutines
!      xios_dyn3dmem_init : context / calendar / domain / axis initialisations
!
! Initialisation of communicator between LMDZ and XIOS is done elsewhere: wxios_init called by init_const_mpi 
!                                                                         (one of the first calls in gcm.F90)
