This program uses the library module ftp to automate publication of data on a remote web site.

> webput:publish("bingo.baz.dobedo.se","jimbo23","waX2p34",
	       "/home/joe/html/mirror",
	       "/pub/acct2754/html").
ok

The above command does the following:

1. FTP's to the host bingo.baz.dobedo.se
2. Logs in as user jimbo23 with password waX2p34.
3. Copies all the files in the local directory /home/joe/html/mirror to /pub/acct2754/html
