 /**
- * \ingroup ndn-helpers
- * \brief Adding Ndn functionality to existing Nodes.
- *
- * This helper enables pcap and ascii tracing of events in the ndn stack
- * associated with a node.  This is substantially similar to the tracing that
- * happens in device helpers, but the important difference is that, well, there
- * is no device.  This means that the creation of output file names will change,
- * and also the user-visible methods will not reference devices and therefore
- * the number of trace enable methods is reduced.
- *
- * Normally we eschew multiple inheritance, however, the classes
- * PcapUserHelperForNdn and AsciiTraceUserHelperForNdn are treated as
- * "mixins".  A mixin is a self-contained class that encapsulates a general
- * attribute or a set of functionality that may be of interest to many other
- * classes.
