	help
	  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.

	  It's highly recommended to NOT strip bpftrace binary.
	  To do so, add "bpftrace" to BR2_STRIP_EXCLUDE_FILES.
