How do I setup anonymous ftp on my AIX system?

(stolen from Peter Klee posting)

Have a look at '/usr/lpp/tcpip/samples/anon.ftp'. It is a shell script
and will set up a anonymous ftp site on your local RS/6000. Note: the
ftpd that comes with AIX does not support the display messages every
time a user changes a directory or even when they login.
