Other features

• Single filed configurations on pyproject.toml
• Single sourced versioning: single-source
• Command alias: make

  • unittest workflow

Directory structure

Do you think the directory tree looks poor? Because all configurations are aggregated in pyproject.toml, we don't need any tool specific configuration files.
