! Subroutine: psi_bld_tmpovrl
! Build initial versions of overlap exchange lists.
! When the descriptor is for a large index space, we cannot build
! the data exchange lists "on-the-fly", but we also want to keep using the
! same format conversion routines we use in the small index space case,
! hence this adapter routine.
!
!
! Arguments:
! iv(:) - integer Initial list.
! index
! nprocs (sharing it)
! procs(1:nprocs)
! End marked with -1
!
! desc - type(psb_desc_type). The communication descriptor.
! info - integer. return code.
