  [1X1.1  [33X[0;0YWhat  is  the  Role  of  the  [5XGradedRingForHomalg[105X[101X[1X Package in the [5Xhomalg[105X[101X[1X[101X
  [1XProject?[133X[101X
  
  [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
  
  
  [1X1.2 [33X[0;0YFunctionality[133X[101X
  
  [33X[0;0YThe  package  [5XGradedRingForHomalg[105X  on  the  one  hand  builds on the package
  [5XMatricesForHomalg[105X   and   on   the   other   hands   adds  functionality  to
  [5XMatricesForHomalg[105X.[133X
