About SageMath

   "Creating a Viable Open Source Alternative to
    Magma, Maple, Mathematica, and MATLAB"

SageMath fully supports all major Linux distributions, recent versions of
macOS, and Windows (using Cygwin or Windows Subsystem for Linux).

The traditional and recommended way to install SageMath is from source via
Sage-the-distribution (https://www.sagemath.org/download-source.html).
Sage-the-distribution first builds a large number of open source packages from
source (unless it finds suitable versions installed in the system) and then
installs the Sage Library (sagelib, implemented in Python and Cython).


About this pip-installable source distribution
----------------------------------------------

This pip-installable source distribution ``sagemath-bliss`` is a small
optional distribution for use with ``sagemath-standard``.

It provides a Cython interface to the ``bliss`` library for the purpose
of computing graph (iso/auto)morphisms.

However, these system packages will not be used for building Sage
because using Python site-packages is not supported by the Sage distribution;
