+     "bpftrace is a high-level tracing language for Linux enhanced Berkeley
+Packet Filter (eBPF) available in recent Linux kernels (4.x).  bpftrace uses
+LLVM as a backend to compile scripts to BPF-bytecode and makes use of BCC for
+interacting with the Linux BPF system, as well as existing Linux tracing
+capabilities: kernel dynamic tracing (kprobes), user-level dynamic
+tracing (uprobes), and tracepoints.  The bpftrace language is inspired by awk
+and C, and predecessor tracers such as DTrace and SystemTap.  bpftrace was
+created by Alastair Robertson.")
