+ (description
+ "Numexpr is a fast numerical expression evaluator for NumPy. With it,
+expressions that operate on arrays are accelerated and use less memory than
+doing the same calculation in Python. In addition, its multi-threaded
+capabilities can make use of all your cores, which may accelerate
+computations, most specially if they are not memory-bounded (e.g. those using
+transcendental functions).")
