!=========================================================================

! These are stub functions that do the right thing (usually nothing)
! in case DM_PARALLEL is not compiled for.
! This file, src/module_dm_stubs.F is copied to src/module_dm.F  when
! the code is built.
! If, on the other hand, a DM package is specified, the module_dm.F 
! provided with that package (e.g. RSL) is copied from /external/RSL/module_dm.F
! into src/module_dm.F.
! It is important to recognize this, because changes directly to src/module_dm.F
! will be lost!
