+    This writes the details to standard error and the log. The reporter is
+    installed for the lifetime of the object so typically you would put this
+    at the top of main().
+
+    An alternative is to make it a global variable but for this to cover all
+    possible cases, there can be no other global variables with non trivial
+    constructors that can report a fatal error. Also, the Log would need
+    to be guaranteed to be set up for this handler to work.
