+ Chrome V8 profiling log processor

+</h3>

+<p>

+Process V8's profiling information log (sampling profiler tick information)

+in your browser. Particularly useful if you don't have the V8 shell (d8)

+at hand on your system. You still have to run Chrome with the appropriate

+<a href="https://code.google.com/p/v8/wiki/ProfilingChromiumWithV8">

+ command line flags</a>

+to produce the profiling log.

+</p>

+<h4>Usage:</h4>

+<p>

+Click on the button and browse to the profiling log file (usually, v8.log).

+Process will start automatically and the output will be visible in the below

+text area.

+</p>

+<h4>Limitations and disclaimer:</h4>

+<p>

+This page offers a subset of the functionalities of the command-line tick

+processor utility in the V8 repository. In particular, this page cannot

+access the command-line utility that provides library symbol information,

+hence the [C++] section of the output stays empty. Also consider that this

+web-based tool is provided only for convenience and quick reference, you

+should refer to the

+<a href="https://code.google.com/p/v8/wiki/V8Profiler">

+ command-line</a>

+version for full output.

+</p>
