## NAME
    [Dpkg::Deps::Union](https://www.chedong.com/phpMan.php/perldoc/Dpkg%3A%3ADeps%3A%3AUnion/markdown) - list of unrelated dependencies

## DESCRIPTION
    This class represents a list of relationships. It inherits from [Dpkg::Deps::Multiple](https://www.chedong.com/phpMan.php/perldoc/Dpkg%3A%3ADeps%3A%3AMultiple/markdown).

## METHODS
    $dep->output([$fh])
        The output() method uses ", " to join the list of relationships.

    $dep->implies($other_dep)
    $dep->get_evaluation($other_dep)
        These methods are not meaningful for this object and always return undef.

    $dep->simplify_deps($facts)
        The simplification is done to generate an union of all the relationships. It uses
        $simple_dep->merge_union($other_dep) to get its job done.
