+    longDescription = ''
+       The interval package for real-valued interval arithmetic allows one to
+       evaluate functions over subsets of their domain. All results are verified,
+       because interval computations automatically keep track of any errors.
+
+       These concepts can be used to handle uncertainties, estimate arithmetic
+       errors and produce reliable results. Also it can be applied to
+       computer-assisted proofs, constraint programming, and verified computing.
+
+       The implementation is based on interval boundaries represented by
+       binary64 numbers and is conforming to IEEE Std 1788-2015, IEEE standard
+       for interval arithmetic.
