+%description
+    OpenNN is a software library written in C++ for predictive
+    analytics. It implements neural networks, the most successful
+    deep learning method. The main advantage of OpenNN is its high
+    performance. This library outstands in terms of execution speed
+    and memory allocation. It is constantly optimized and parallelized
+    in order to maximize its efficiency. Some typical applications of
+    OpenNN are function regression (modelling), pattern recognition
+    (classification) and time series prediction (forecasting).
