This program uses Perl's Net::FTP library to do its FTP transfers.  The
library has global configuration information stored in
/etc/perl/Net/libnet.cfg. If you need to, eg, have all external transfers
use passive FTP, you'd want the ftp_ext_passive config variable to be set
to a true value.  The library can also be configured to use a proxy, and
probably other things.
