+    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.
