RVM (Ruby Version Manager) allows you to easily install, manage, and work with multiple ruby environments from interpreters to gemsets. It provides commands to install different Ruby versions, switch between them, create gemsets to isolate groups of gems for different applications, and manage gems within gemsets. RVM improves on traditional methods of handling Ruby environments by offering a simple command line interface and reducing the complexity of working with multiple versions and configurations.
