Write a man page, but it's 2016, you don't have to write it in ROFF... It got a lot easier to get people to write or update man pages for a bunch of in-house CLI tools when I found ronn https://rtomayko.github.io/ronn/ https://rtomayko.github.io/ronn/ which starts from markdown (you'll still get a lot of copy/paste formatting from your other man pages but at least it'll be readable.)
