A note on the cover: this is an original AVUS cover from 1959. I've merely padded it slightly to match the aspect ratio of the GPL programs, and changed the dates to match the event dates used in GPL.
You don't need to download this program set - it comes with the track.
In any event, Schleizer Dreieck (or "Schleizer Triangle", according to the babelfish) is a real-live German race circuit, built on public roads. It's Germany's oldest race track, having held its first race in 1923. It's also a scary place to drive a 1967 F1 car - very fast long straights, followed by incredibly tight corners, sort of like Le Mans, only more so...
(And yes, it is the same (albeit cleaned-up) artwork that we used on the Detroit cover. I like the art, it fits Snetterton better than Detroit, and Detroit sucks. If this bothers you, you can fail to install 'page0.pbf' and use the cover that comes with the track.)
These sets feature the original, real-life covers used in the 1967 F1 season (with the exception of Rouen, which is from 1968). The covers have been taken from scans of the originals, and reformatted, color corrected, cleaned up, and in some cases largely re-created from scratch.
Note: an alternate cover can be found in the 'nite-bonuspack' collection.
Sopheve, a fanstasy track from Ryk Penfold.
No, I'm just kidding - it is (of course) probably the most-requested GPL track since day 1, a version of Monza that includes the full banked oval. Finally, we can all relive the last 20 minutes of the movie Grand Prix, though hopefully without that whole "flying off the banking into a tree" part!
Note that this track has largely been supplanted by 'monza10k'.
I suppose this program does have one minor feature over the original - it's in English (which is certainly a feature if you don't happen to understand Finnish!) This matches nicely with the generally-in-English nature of the 11 original GPL track programs, at least in the US version of the game...
No, but seriously... According to the website, over 500 people have downloaded the track, and maybe some of those folks would like a spiffy ol' BAPOM program set for the beastie. I know at least one guy would, 'cause he requested it!
