Obtained from: The NYS project

This is a ported/modified version of the ypxfr program from the yps-0.21
package from the NYS project. This program is normally invoked by ypserv
when it receives a yppush command from an NIS master. It can also be
run from the command line to grab copies of maps when initializing a
slave server.

This program has been hacked in the following ways:

- rpcgen'ed new yp_xdr.c, yp_svc.c and yp_clnt.c files. The old ones were
  rather grody.

- Changed certain function names (prefended a _ to them) to avoid conflicts
  with certain functions lurking within libc. One major problem here is
  that ypxfr needs to bind to a YP master in order to work correctly,
  but it can't use the _yp_bind function inside libc because that
  function only lets you bind to a domain, not a specific host. Lots
  of head scratching here.

- Converted from GDBM to DB at gunpoint.

- Removed lots of really nasty looking DEBUG code to try to reduce clutter.

- Incorporated some of the library code supplied with yps-0.21 on which
  ypxfr was dependent.

This program still needs to be cleaned up just as a matter of principle:
I get all icky just looking at it sometimes.
