How tools get listed

A tool appears in this directory once it is finished and usable. Each listing links to two places: the tool itself, and a page on this site that explains how it works, which inputs it supports, and its known limitations.

More tools will be added over time. There are no placeholder listings, so if it's here, you can use it today. Read more about AllOfCode.
