Replying to [comment:13 malb]:
> Hang on, that means then that the user should (a) reverse the variables
and (b) choose degneglex to get degrevlex as defined in Singular?
Yes, otherwise we would not had have to implemented `dp_asc` (which was
really hard). Have a look at `pbori.pyx`. `DegRevLex` is exactly
implemented like this. (And `DegNegLex` is Sage is exactly `PolyBoRi`'s
`dp_asc`.)
