      subroutine mom_rest_in (fname, ids, ide, jds, jde)

!=======================================================================
!     input routine for ocean restarts

!     data may be sized differently in x and y from the global fields.
!     fields may be written with or without a time dimension. data
!     should be defined with the routine defvar and written with putvar.
!     if no time dimension, then data is only written once per file.
!     make sure the it, iu, ib, and ic arrays and are defining the
!     correct dimensions. ln may also need to be recalculated.

!   inputs:
!     fname              = file name
!     ids, ide ...       = start and end index for data domain
