Each planet file has its own torrent. A new planet file means using a 
new torrent to download it.

To simplify downloading the lastest planet, you'll find a 
planet-latest.pbf.torrent similar to the planet-latest.pbf (it's a 
symlink to the last planet available).

If you want to automate downloading new planet thru torrents, for 
example to seed them, there's a rss.xml file you can use. Many 
bittorrent clients support RSS to automate downloads.
