  37  * DESCRIPTION: This file implements the hooks between old style DBM calls and
  38  *              the shim version of the same calls. By including this file a
  39  *              C files calls are diverted to the shim versions.
  40  *
  41  *              Do NOT include this in the shim code itself or you will be
  42  *              unable to make real dbm calls.
  43  *
  44  *              Do NOT include this in the client side NIS files.
  45  *
  46  *              One day it may be possible to implement a more elegant version
  47  *              of this based on the linkers 'interposition' mechanism.
