# Code Maintenance
- [ ] Test suite
  - [ ] Figure out how to test for memory leaks
  - [ ] Space leak via Neil Mitchell
  - [ ] Valgrind?
  - [x] Test edge cases (non-standard chunk sizes)
  - [ ] Test multithreaded (start unpacking in one thread)
- [ ] CI
  - [x] Nix integration (`cabal2nix`)
    - [x] Dependent on upstream
# Performance

  conditions
# Bugs

# Features
- [ ] xar? 7zip?
# Documentation
- [ ] Add example in haddocks
