You can specify both torrent file with -T option and URIs. By doing this,
download a file from both torrent swarm and HTTP/FTP server at the same time,
while the data from HTTP/FTP are uploaded to the torrent swarm. For single file
torrents, URI can be a complete URI pointing to the resource or if URI ends
with '/', 'name' in torrent file is added. For multi-file torrents, 'name' and
'path' in torrent are added to form a URI for each file.
