 14:   Level: beginner

 16:   Notes:
 17:   Each PETSc class, for example `Vec`, has a viewer method associated with that class, for example `VecView()`, that can be used
 18:   to view, display, store to a file information about that object, etc. Each class also has a method that uses
 19:   the options database to view the object, for example `VecViewFromOptions()`.

 21:   See `PetscViewerType` for a list of all `PetscViewer` types.
