+        <p>The Linux Trace Toolkit: next generation is an open source system software package

+        <p>
+            Configure and build Erlang with LTTng support:
+        </p>
+        <p>For LTTng to work properly with Erlang/OTP you need
+            the following packages installed:</p>
+
+      <list type="bulleted">
+          <item><p>LTTng-tools: a command line interface to control tracing sessions.</p></item>
+          <item><p>LTTng-UST: user space tracing library.</p></item>
+      </list>
+
+      <p>On Ubuntu this can be installed via <c>aptitude</c>:</p>
+
+      <code type="none">$ sudo aptitude install lttng-tools liblttng-ust-dev</code>
+      <p>See <url href="http://lttng.org/docs/#doc-installing-lttng">Installing LTTng</url>
+          for more information on how to install LTTng on your system.</p>
+
+      <p>After LTTng is properly installed on the system Erlang/OTP can be built with LTTng support.</p>
+ 
+
+<code type="none">$ ./configure --with-dynamic-trace=lttng
