RV, A NEW KIND OF RUBY MANAGEMENT TOOL

Summary from the TLDR newsletter

rv is a dependency manager for Ruby written in Rust. It manages both Ruby versions and gems at once, so developers can run whatever they want to run without having to worry about the environment being correct. rv brings all the tricks and innovations of cargo, npm, and uv into a tool for Ruby. It can currently auto-switch between installed Ruby versions in zsh and install precompiled Ruby 3.4.x on macOS and Ubuntu in one second flat.
