+Description
+    An extrapolation-algorithm, based on the linearly implicit Euler method
+    with step size control and order selection.
+
+    The implementation is based on the SEULEX algorithm in
+    \verbatim
+        "Solving Ordinary Differential Equations II: Stiff
+         and Differential-Algebraic Problems, second edition",
