*
* PETSc is a library that supports, among other things, a large number of
* linear algebra data structures and algorithms, in much the same way as we
* interfaces to many PETSc functions and data structures in the PETScWrapper
* namespace, that allow the use of PETSc in much the same way as deal.II's
* own linear algebra classes are used. The use of these wrappers is explained
- * in the step-17 and step-18 example programs.
+ * in the step-17 and step-18 example programs, as well as in the @ref
+ * PETScWrappers module.
*
* PETSc can be obtained from http://www.mcs.anl.gov/petsc/.

+ * @subsection METIS METIS
+ *
+ * METIS is a tool that allows to partition a graph into chunks of roughly
+ * equal size. We use it to subdivide a domain into blocks that have about the
+ * same number of cells, when distributing work for parallel programs. METIS
+ * can be obtained from http://www-users.cs.umn.edu/~karypis/metis/index.html
