+     "AlgoPy provides a functionality to differentiate functions implemented
+as computer programs by using Algorithmic Differentiation (AD) techniques in
+the forward and reverse mode.
+
+The forward mode propagates univariate Taylor polynomials of arbitrary order.
+Hence it is also possible to use AlgoPy to evaluate higher-order derivative
+tensors.  The reverse mode is also known as backpropagation and can be found
+in similar form in tools like PyTorch.  Speciality of AlgoPy is the
+possibility to differentiate functions that contain matrix functions as
++,-,*,/, dot, solve, qr, eigh, cholesky.")
