Minor correction: Ariane -> ESA (European Space Agency). Ariane is the name of the rocket (and 'Arianespace' the name of the company that does the actual launching for ESA, but that's just part of ESA with a different name).

BTW, I saw they have a Soyuz manual on their website: http://www.arianespace.com/launch-services-soyuz/Soyuz-Users... [pdf]
