'''This demonstrates an FTP "bookmark". This connects to an ftp site; does a
few ftp stuff; and then gives the user interactive control over the session. In
this case the "bookmark" is to a directory on the OpenBSD ftp server. It puts
you in the i386 packages directory. You can easily modify this for other sites.
