This shows the changes needed to a System V or UNIX 5.0 UUCP to
implement the -z option.  The -n option is in the standard system,
but you usually want to be notified if something goes wrong.

I looked at the 4.0 sources and compared them to the 5.0.  The programs
have changed but the changes aren't many.  Only uucp.h, uux.c, and uuxqt.c
need be changed.  I'll be putting in the changes once I get permission from
our systems people.
