! Subroutine: psb_get_overlap
! Extracts a list of overlap indices. If no overlap is present in
! the distribution the output vector is put in the unallocated state,
! otherwise its size is equal to the number of overlap indices on the
! current (calling) process.
!
! Arguments:
! ovrel(:) - integer, allocatable Array containing the output list
! desc_a - type(psb_desc_type). The communication descriptor.
! info - integer. return code.
