+
+long_description    Tensor2Tensor, or T2T for short, is a library \
+                    of deep learning models and datasets designed to \
+                    make deep learning more accessible and accelerate \
+                    ML research.  T2T is now deprecated. Users are \
+                    encouraged to use the successor library Trax.
