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

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

Installing locally, requires a number of dependencies and OS package dependencies.
