asdf is a tool version manager. All tool version definitions are
contained within one file (
.tool-versions) which you can check in
to your project's Git repository to share with your team, ensuring
everyone is using the exact same versions of tools.
The old way of working required multiple CLI version managers, each
with their distinct API, configurations files and implementation
$PATH manipulation, shims, environment variables,
asdf provides a single interface and configuration file
to simplify development workflows, and can be extended to all tools
and runtimes via a simple plugin interface.
