Dynamic Text Replacement

I couldn’t find this, and never saw anyone mention it. And I have no idea where to place it. But it seems so neat, I really wanted to let you guys see it. It may come in handy for some of you. I haven’t used it, but from what I read, it sounds really cool.
Buuuuut you probably all read this when it was written, cause I mean it is ala, and I bet real developers read that… I don’t…

So hope that you guys find that as interesting as I did!
