This is really out of my league, and I wouldn't bring it up except that I'd like to understand how things are done here - at
unix.se. That said:
While searching, I found a Q&A that addressed my question perfectly on the SO forum. As you can see it's quite old, and also classified as off-topic and closed. Fair enough, but it seemed quite relevant here, so I posed a question in SO.meta about migrating it.
I got an answer to my question that I felt was credible, but not quite "satisfactory" if you know what I mean. And so, I am posting a question here to ask if there is a different procedure at
unix.se for handling such things, or if there are other suggestions.
