Conventions

We suggest the following conventions concerning suffixes of file names:

.dfg For general problem files, including formulae, clauses, proofs at the same time.
.frm For problem files containing at least lists of formulae.
.cnf For problem files containing at least lists of clauses in conjunctive normal form.
.dnf For problem files containing at least lists of clauses in disjunctive normal form.
.prf For problem files containing at least lists of proofs.
