## What it is
RVM (Ruby enVironment Manager) is a command-line tool for installing, managing, and switching between multiple Ruby interpreters and gem environments on UNIX-like systems. It supports MRI, JRuby, Rubinius, TruffleRuby, and mruby, and manages per-project isolated gemsets.

## Use cases
- install multiple ruby versions on one machine
- switch ruby versions per project
- manage isolated gemsets for rails apps
- install jruby or truffleruby easily
- set a default ruby for my shell
- manage ruby environments without sudo conflicts
- deploy apps with self-contained ruby environments

## When to choose
- you need to juggle many Ruby versions and interpreters (MRI, JRuby, Rubinius, TruffleRuby)
- you want built-in gemset isolation per project
- you want automatic installation of build dependencies via autolibs
- you work on UNIX-like systems or Ubuntu with a dedicated package

## When to avoid
- you prefer a lighter, shell-agnostic version switcher like chruby or rbenv
- you only need one system Ruby version
- you need first-class native Windows support (only Cygwin/WSL is supported)
- you want a non-shell-based tool for scripted/CI environments where shell function sourcing is awkward
