eim (Erlang Installation Manager) manages multiple Erlang/OTP installations, allowing easy switching between versions for development and testing.
The tool handles downloading, building, and switching between Erlang versions. This is useful when projects require specific Erlang versions or when testing compatibility.
Similar to tools like nvm for Node.js, eim simplifies Erlang version management.
