+    longDescription = ''
+       libtopology provides a portable abstraction (across OS,
+       versions, architectures, ...) of the hierarchical topology of
+       modern architectures, including NUMA memory nodes, sockets,
+       shared caches, cores and simultaneous multithreading.  It also
+       gathers various attributes such as cache and memory
+       information.  It primarily aims at helping high-performance
+       computing applications with gathering information about the
+       hardware so as to exploit it accordingly and efficiently.
+
+       libtopology may display the topology in multiple convenient
+       formats.  It also offers a powerful programming interface to
+       gather information about the hardware, bind processes, and much
+       more.
