I have a bunch of half-finished, partially working, user-hostile tools. I can't bundle or release them, it would take too long to write what they do, and don't do. I could do something like you say, but again, as you say, I'd bet someone else has already mostly done it.

I wonder if I could cobble together from what I have something that I could make public. Next time I cross-reference stuff I'll leave a trail of bread-crumbs to see if I can regularize/semi-automate it.
