However, this repository contains just the Mathics3 Kernel: Pythonmodules for WL Built-in functions, variables, core primitives,e.g., Symbol, a parser to create Expressions, and an evaluator toexecute them.

The home page for Mathics ishttps://mathics.org, where you will find a list of screenshots and components making up the system.
