-Tracing template
-----------------
-Test_shell has an optional tracing feature. It can be enabled by running
-with the --enable-tracing option. Tracing causes events to be dropped into
-a trace file during runtime.
-
-This HTML file can be used to render the output from the trace. You'll need
-to rename your trace data to "trace_data.js" in the same directory with this
-HTML file, and then you can visualize the trace.
-
-Lots of work remains on this tracing tool; currently development is on hold.
