    """Aspcud: Package dependency solver

       Aspcud is a solver for package dependencies. A package universe
       and a request to install, remove, or upgrade packages have to
       be encoded in the CUDF format. Such a CUDF document can then be
       passed to aspcud along with an optimization criteria to obtain
       a solution to the given package problem."""
