+		<description>&lt;p&gt;&lt;a href=&quot;http://coz-profiler.org/&quot;&gt;The Coz profiler&lt;/a&gt;, a nice
+profiler able to run benchmarking experiments on the instrumented
+multi-threaded program, finally
+&lt;a href=&quot;https://tracker.debian.org/pkg/coz-profiler&quot;&gt;made it into
+Debian unstable yesterday&lt;/A&gt;.  Lluís Vilanova and I have spent many
+months since
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Coz_can_help_you_find_bottlenecks_in_multi_threaded_software___nice_free_software.html&quot;&gt;I
+blogged about the coz tool&lt;/a&gt; in August working with upstream to make
+it suitable for Debian.  There are still issues with clang
+compatibility, inline assembly only working x86 and minimized
+JavaScript libraries.&lt;/p&gt;
+
+&lt;p&gt;To test it, install &#39;coz-profiler&#39; using apt and run it like this:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+&lt;tt&gt;coz run --- /path/to/binary-with-debug-info&lt;/tt&gt;
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;This will produce a profile.coz file in the current working
+directory with the profiling information.  This is then given to a
+JavaScript application provided in the package and available from
+&lt;a href=&quot;http://plasma-umass.github.io/coz/&quot;&gt;a project web page&lt;/a&gt;.
+To start the local copy, invoke it in a browser like this:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+&lt;tt&gt;sensible-browser /usr/share/coz-profiler/viewer/index.htm&lt;/tt&gt;
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;See the project home page and the
+&lt;a href=&quot;https://www.usenix.org/publications/login/summer2016/curtsinger&quot;&gt;USENIX
+;login: article on Coz&lt;/a&gt; for more information on how it is
+working.&lt;/p&gt;
