+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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
