Exercism Command-Line Client

The CLI provides a way to do the problems on exercism.io.

Important: If you're looking for instructions on how to install the CLI. Please read Installing the CLI

This CLI ships as a binary with no additional runtime requirements. This means that if you're doing the Haskell problems on exercism you don't need a working Python or Ruby environment simply to fetch and submit exercises.
