+
+  <description-long>
+    This module is a working example for building a YARP device that exploits the iMotor YARP
+    interfaces to interact with the motion control module.
+    Specifically to this example, we are defining a <i><b>PolyDriver</b></i> device that interacts with the
+    pointer to the <i><b>iMotor</b></i> yarp interface and prints the motor temperatures to an output port.
+    Those temperatures value can be obtained exploiting the interface method <i>getTemperatures()</i> and
+    saved to a c-array of doubles.
+    Considering that, a properly built yarp module should derive from the public interface
+    <i><b>yarp::os::RFModule</b></i>, whose complete explanation is available at <a href="https://yarp.it/latest/thrift_tutorial_simple.html#thrift_tutorial_simple_module">this link</a> the
+    following methods should be overridden:
+    <list type="bullet">
+      <item>
+        <description>configure()</description>
+      </item>
+      <item>
+        <description>getPeriod()</description>
+      </item>
+      <item>
+        <description>updateModule()</description>
+      </item>
+      <item>
+        <description>close()</description>
+      </item>
+    </list>
+
+    In order to use this module, whose final target is to print at the port called <i><b>/portprefix/motor_temperatures:o</b></i> the temperatures of the motors connected, the following steps
+    should be done:
+    <list>
+      <item>
+        <description>supposed to have the correct setup running on the yarpserver sending data to state ports</description>
+      </item>
+      <item>
+        <description>./build/MotorTemperaturePublisher --from app/conf/config.ini</description>
+      </item>
+    </list>
+
+    This will instantiate the aformentioned port, where with a frequence of <i><b>_updatePeriod</b></i> time,
+    the following values will be streamed on the port:
+
+    <list>
+      <item>
+        <description>timeStamp | temperature_motor_0 | boolean_limit_overcame_0 | ... | temperature_motor_N | boolean_limit_overcame_N |</description>
+      </item>
+    </list>
+
+    the <i><b>config.ini</b></i> file should be filled in with the following data:
+    <list>
+      <item>
+        <description>robotname: name of the robot as set in the configuration files</description>
+      </item>
+      <item>
