##
    # Htgroup accesses apache-compatible group files.  Htgroup can be used to
    # provide group-based authentication for users.  Currently Htgroup is not
    # directly integrated with any authenticators in WEBrick.  For security,
    # the path for a digest password database should be stored outside of the
    # paths available to the HTTP server.
    #
    # Example:
    #
    #   htgroup = WEBrick::HTTPAuth::Htgroup.new 'my_group_file'
    #   htgroup.add 'superheroes', %w[spiderman batman]
    #
    #   htgroup.members('superheroes').include? 'magneto' # => false
