Is it possible to "script" and FTP session???

["George Lenzer" <glenzer chuhpl lib oh us>]

A friend of mine asked if I could set up his Linux box to automatically FTP
some files from a specific directory every time he connects to the Internet.
He is using 'ifup ppp0' to connect.  I had done something similar to this
for myself but using E-mail.  Is there any way to get FTP or 'ncftp' to
automatically log in to an ftp site, change to a local directory and then
transfer files upon connection?  I looked at the man pages for 'ftp' and it
looked like the macdef command would do this to a certain extent.  Am I on
the right track?

Thanks,
