   MODULE module_check_a_mundo 5

!<DESCRIPTION>
!
! Contains subroutines that check the consistency of some namelist 
! settings. Some namelist settings depend on other values in the 
! namelist. The routine check_nml_consistency can detect quite a 
! few fatal inconsistencies. These are all bundled up as a convenience.
! The fatal errors are reported, and after the routine completes, then
! a single call to wrf_error_fatal is issued. The setup_physics_suite routine
! has only one fatal call, so that routine does not need this user-
! friendly concept of bundling errors. The set_physics_rconfigs 
! routine does not detect any problems that would result in a fatal
! error, so the bundling of errors is also not required there.
!
!   SUBROUTINE check_nml_consistency :
!      Check namelist settings for consistency
!
!   SUBROUTINE setup_physics_suite : 
!      Interpret user setting as referring to which supported schemes
!      Currently: conus and tropical
!
!   SUBROUTINE set_physics_rconfigs :
!      Check namelist settings that determine memory allocations.
