+# Simple timing test for the MPI library.  Basically, we use prime
+# generation as a timing test, since it exercises most of the pathways
+# of the library fairly heavily.  The 'primegen' tool outputs a line
+# summarizing timing results.  We gather these and process them for
+# statistical information, which is collected into a file.
