* [miri](https://github.com/solson/miri)
If your changes break one of these projects, you need to fix them by opening
a pull request against the broken project. When you have opened a pull request,
you can disable the tool via `src/tools/toolstate.toml`.
a pull request against the broken project asking to put the fix on a branch.
Then you can disable the tool building via `src/tools/toolstate.toml`.
Once the branch containing your fix is likely to be merged, you can point
the affected submodule at this branch.
Don't forget to also add your changes with
```
git add path/to/submodule
```
outside the submodule.
It can also be more convenient during development to set `submodules = false`
in the `config.toml` to prevent `x.py` from resetting to the original branch.
