+The project provides an interface (<code>RandomVariableDifferentiableInterface</code>)
for random variables which provide automatic differentiation.
-The interfaces extends <code>RandomVariableInterface</code> and
+The interface extends <code>RandomVariableInterface</code> and
hence allows to use auto-diff in all Monte-Carlo contexts
(via a replacement of the corresponding parameters / factories).
