It can be cumbersome when you have multiple projects and environments with configuration files which need to be upgraded and keep in sync regularly. Check-config will help you with i.e. making sure that the configuration file have the (upgraded) settings.
Check-config works with checker files in which you define checks, ie
```checkers.toml
[".gitignore".lines_present] lines = ".venv" ```
With check-config you can check (for example in a build pipeline) whether your files passed the checks.
Most checks can also be automatically fixed with check-config --fix, so in this case a missing line will
be added to the .gitignore.
A large number of file types and checks are supported or will be supported in the near future.
