If you are brave and do want to give Do a try in your own projects, it is *by design* a single long file that you can copy and paste into your own projects. That's not the most elegant way of doing things (heh), but it does mean you can easily vendor it in when bootstrapping would otherwise be a problem.
You can also use `do` as a development dependency, so `pdm run do` should work. Lots of ways of running it, depending on what your project needs.
