Lots of documentation

I've spent the last couple days writing as much documentation as I can for one of the tools I created. My outline calls for six "chapters" and five shorter "appendices." Along the way I realized a small issue with the tool itself and corrected that. After writing 68 KB of prose and code, I just have one chapter and three appendices to go. I have two days to finish those and a (hopefully shorter) explanation of my part of another project.
