   Support
       Please direct usage questions or support issues to the mailing list:

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

                  :             collapses to "1-5 7 9-11". This is useful for
                  :             consolidating long lists. Default = no collapse.
        Throws    : n/a.
