  [33X[0;0YThe  [5Xhomalg[105X  project  [hpa10]  aims  at  providing  a  general  and abstract
  framework  for  homological  computations.  The  package [5XGradedRingForHomalg[105X
  enables  the  [5Xhomalg[105X  project  to  endow commutative rings in [5Xhomalg[105X with an
  Abelian grading.[133X
