* Construct a TriangulationDescription::Description. In contrast

* triangulation and the TriangulationDescription::Description for all
- * processes in its group, which is communicated.
+ * processes in its group, which is then communicated.

* This function can also be used to read an external mesh only once (by
- * the root process and a group consisting all processes). The following
