It's an experimental way to calculate how "volatile" is a project

source code repository, by comparing the amount of dead code (rarely touched)

with the amount of actively modified one. More or less detailed theoretical summary

is in [theory.pdf](https://github.com/yegor256/volatility/raw/master/theory.pdf).

You need to have Ruby 2.6+ installed. Then you install this tool:

```bash

$ gem install volatility

```

Then, you run it:

```bash

$ volatility --help

```
