I see. YEs, it respect the spec. But as it is the this option
(APT::Solver::aspcud::Preferences) is actually useless because aspcud
will never receive this information, correct ? 

This command line comes from this bug #823906 . Maybe you should warn
the user that (s)he should use APT::Solver::Preferences instead ?

This make me think that maybe it would be worth adding the solver to
be called to the edsp file as well. Something like :

Solver: aspcud
Preferences: ...

This will make the edsp fully contained.

thanks for your quick reply.
