Introduction

What is the Role of the &GradedRingForHomalg; Package in the &homalg; Project? The &homalg; project aims at providing a general and abstract framework for homological computations. The package &GradedRingForHomalg; enables the &homalg; project to endow commutative rings in &homalg; with an Abelian grading.

Functionality The package &GradedRingForHomalg; on the one hand builds on the package &MatricesForHomalg; and on the other hands adds functionality to &MatricesForHomalg;.
