Feature for testing the presence of (lib)brial

class sage.features.brial.Brial(*args, **kwds)

Bases: JoinFeature

A sage.features.Feature describing the presence of sage.rings.polynomial.pbori.

The sage.rings.polynomial.pbori module in turn depends on the presence and usability of libbrial – a slightly more modern fork of PolyBoRi, which hopefully explains the name.
