```bash
spack install gekkofs
# for installing tests dependencies and running tests

### TODO

- [x] Base Spack functionality, versions, and configuration support
- [x] Documentation
- [x] Advanced functionality, more detailed configuration support, e.g., Parallax and Prometheus
- [x] More easy way to get path to client library
- [x] Add GekkoFS client wrapper for `LD_PRELOAD`
- [ ] Add final version to main Spack repository if possible. (Not possible right now as it not clear how 3rd party libraries should be treated.
