       This automatically builds PETSc with both MPI and the algebraic
-      multigrid preconditioner package Hypre (which we use in step-40). You
-      may wish to put the <code>export</code> commands into
-      your <code>~/.bashrc</code> or <code>~/.cshrc</code> files, with the
-      first one replaced by something of the kind

+
+	make test
+      </pre>
+      will self-check the serial (and MPI) implementation of PETSc.
