sage

This repository used to be the user-facing mirror of the Sage source tree. As Sage development migrated on 2023-02-01 from https://trac.sagemath.org/ to our new repository on GitHub, https://github.com/sagemath/sage, we have renamed and archived this repository.

General purpose mathematical software system, compatible fork of https://github.com/sagemath/sage supporting modularized installation with pip. Main repository, containing Sage library (src/), modularized pip-installable packages (pkgs/), Sage distribution (build/). Source repo for most packages in https://pypi.org/org/passagemath/
