Comment (by malb):
I should mention that I didn't implement reading from DIMACS files. I did
implement exporting to DIMACS but perhaps some people would find this
interface not that nice. I find it reasonably elegant though because it is
quite modular:
{{{
sage: from sage.sat.converters.polybori import CNFEncoder
sage: solver = sage.sat.solvers.dimacs.DIMACS(filename="mycnf.cnf")
sage: F,s = mq.SR(1,2,2,4,gf2=True,polybori=True).polynomial_system()
sage: encoder = CNFEncoder(solver, F.ring())
sage: _ = encoder(F)
sage: solver.write()
'mycnf.cnf'
}}}
