         * complex argument processing or something, we define a
         * simple version here that takes arguments in as flat a
         * manner as possible, to simplify the XS code, put it in
         * BarnOwl::Intenal::, and write a perl wrapper in BarnOwl.pm
         * that munges the arguments as appropriate and calls the
         * internal version.
