# extra4
Supplements to the Lean 4 [Batteries](https://github.com/leanprover-community/batteries).
All components are unstable but feel free to use whatever you need for your own project!
## Purpose
This is a miscellaneous repository of code that, for a variety of reasons, neither belonged in the standard library nor in development code.
Ideally, everything in here will find its way elsewhere in due time.
That said: this is not a code dump!
All the code in here is curated.
Pull requests are very welcome but they will be carefully reviewed before merging.
