%% QUESTION: Why is this necessary when invoice.sty in this directory
%% already has "\RequirePackage{longtable}" (as of 2012-06-17)?  Are
%% we not actually using invoice.sty for anything?  Is it just there
%% as an example?  In any case, if we don't pull in 'longtable' here,
%% then generating an OTS invoice will fail with the rather clear
%% message "LaTeX Error: Environment longtable undefined", despite the
%% the \RequirePackage in invoice.sty.
