+"""Perf annotate for JIT code.
+
+Linux `perf annotate` does not work with JIT code.  This script takes the data
+produced by `perf script` command, plus the diassemblies outputed by gallivm
+into /tmp/perf-XXXXX.map.asm and produces output similar to `perf annotate`.
+
+See docs/llvmpipe.html for usage instructions.
+
+The `perf script` output parser was derived from the gprof2dot.py script.
