For the benefit of the Don't Starve Modders, and particularly my fellow Up & Away collaborators, I have compiled a video guide demonstrating basic use of Spriter in a Don't Starve modding context.
My sincerest apologies about the quality of the audio in particular - my voice is barely audible on a good day, and right now I'm a bit sick... there's also a rain storm in the background, and it's being recorded through a phone mic.
I tried to filter things as best I could, but it's still not great.
This isn't really a detailed tutorial... but I hope it's at least marginally coherent and helpful to some of you.
