It will be interesting to see the responses to this thread, but I can say that, given that my system also contains a Ruby interpreter, I wouldn’t bother to “do a thing already done,” merely because it is in a different language.   If this tool, already available on GitHub, actually does everything that I need to do, and if I can actually get the thing running under the ruby command instead of the perl command, then I would do so without any hesitation at all.   I would see no credible return-on-investment in a reimplementation in Perl, if a solution to my business problem actually is so readily available.   (I am sure that I will summarily get-clobbered, even more than I usually do for talking at-all, for saying such a travesty on “a Perl forum,” but it is so.   What I want is “to get there, fast,” ideally having done no programming-work at all, not to “get there” with a certain compiler.)
