+ * The layer of ghost cells consists of all cells that are face, edge, or
+ * vertex neighbors of any locally owned cell and that are not locally
+ * owned themselves. In other word, the ghost cells completely enclose the
+ * subdomain of locally owned cells (with the exception of the boundary of
+ * the domain, of course).
+ *
  * The concept of ghost cells has no meaning for triangulations that
  * store the entire mesh on each processor, i.e. the
  * dealii::Triangulation class.  </dd>
