description: "EpetraExt is a set of extensions to Epetra. To allow Epetra to remain\
  \ focused on its primary functionality as a Linear Algebra object support, EpetraExt\
  \ was created to maintain additional support for such capabilities as transformations\
  \ (permutations, subblock views, etc.), coloring support, partitioning (Zoltan),\
  \ and I/O."
