Written by Daniel Silverstone <dsilvers@digital-scurf.org> with serious
cargo-culting from the sftp transport and the http transport.
It provides the ftp:// and aftp:// protocols where ftp:// is passive ftp
and aftp:// is active ftp. Most people will want passive ftp for traversing
NAT and other firewalls, so it's best to use it unless you explicitly want
active, in which case aftp:// will be your friend.
