+    SciPy is an open source library of scientific tools for Python. SciPy
+    supplements the popular numpy module, gathering a variety of high level
+    science and engineering modules together as a single package.
+    SciPy includes modules for graphics and plotting, optimization,
+    integration, special functions, signal and image processing, genetic
+    algorithms, ODE solvers, and others.
