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