This chapter explores the tool rye, which is written in Rust and inspired by Rust's packaging setup. It discusses the differences between rye and PIPX, highlighting that rye doesn't require a version of Python to be installed. The speakers also discuss the challenges of packaging and dependency management in Python, comparing it to Rust's more recent design. The chapter ends with a mention of organizing dependencies in a mono repo and a recommendation for the 'MKDocs material' package for documentation building.
