+ * builtin-trace.c
+ *
+ * Builtin 'trace' command:
+ *
+ * Display a continuously updated trace of any workload, CPU, specific PID,
+ * system wide, etc. Default format is loosely strace like, but any other
+ * event may be specified using --event.

+ * Copyright (C) 2012, 2013, 2014, 2015 Red Hat Inc, Arnaldo Carvalho de Melo <acme@redhat.com>

+ * Initially based on the 'trace' prototype by Thomas Gleixner:
+ *
+ * http://lwn.net/Articles/415728/ ("Announcing a new utility: 'trace'")
+ *
+ * Released under the GPL v2. (and only v2, not any later version)
