+ * XXX This sample code was once meant to show how to use the basic Libevent
+ * interfaces, but it never worked on non-Unix platforms, and some of the
+ * interfaces have changed since it was first written.  It should probably
+ * be removed or replaced with something better.
+ *
+ * Compile with:
+ * cc -I/usr/local/include -o time-test time-test.c -L/usr/local/lib -levent
