+description         Recurrent Neural Network Language Modeling Toolkit
+
+long_description    Neural network based language models are nowdays among the \
+                    most successful techniques for statistical language modeling. \
+                    They can be easily applied in wide range of tasks, including \
+                    automatic speech recognition and machine translation, and \
+                    provide significant improvements over classic backoff n-gram \
+                    models.
