description         A conflict-driven nogood learning answer set solver
long_description \
    clasp is an answer set solver for (extended) normal logic programs. \
    It combines the high-level modeling capacities of answer set programming \
    with state-of-the-art techniques from the area of Boolean constraint solving. \
    The primary clasp algorithm relies on conflict-driven nogood learning, \
    a technique that proved very successful for satisfiability checking (SAT).
