+ * This should be the first command in your vtc as it will identify the test
+ * case with a short yet descriptive sentence. It takes exactly one argument, a
+ * string, eg::
+ *
+ *         varnishtest "Check that varnishtest is actually a valid command"
+ *
+ * It will also print that string in the log.
