+/// \brief Test InitLogger
+///
+/// A program used in testing the logger that initializes logging with
+/// buffering enabled, so that initial log messages are not immediately
+/// logged, but are not lost (they should be logged the moment process()
+/// is called.
+///
+/// If -n is given as an argument, process() is never called. In this
+/// case, upon exit, all leftover log messages should be printed to
+/// stdout, but without normal logging additions (such as time and
+/// logger name)
