+SciPy: A scientific computing package for Python
+================================================
+
+Documentation is available in the docstrings and
+online at https://docs.scipy.org.
+
+Contents
+--------
+SciPy imports all the functions from the NumPy namespace, and in
+addition provides:
+
+Subpackages
+-----------
+Using any of these subpackages requires an explicit import.  For example,
+``import scipy.cluster``.
+
+::
+
+ cluster                      --- Vector Quantization / Kmeans
+ fftpack                      --- Discrete Fourier Transform algorithms
+ integrate                    --- Integration routines
+ interpolate                  --- Interpolation Tools
+ io                           --- Data input and output
+ linalg                       --- Linear algebra routines
+ linalg.blas                  --- Wrappers to BLAS library
+ linalg.lapack                --- Wrappers to LAPACK library
+ misc                         --- Various utilities that don't have
+                                  another home.
+ ndimage                      --- n-dimensional image package
+ odr                          --- Orthogonal Distance Regression
+ optimize                     --- Optimization Tools
+ signal                       --- Signal Processing Tools
+ signal.windows               --- Window functions
+ sparse                       --- Sparse Matrices
+ sparse.linalg                --- Sparse Linear Algebra
+ sparse.linalg.dsolve         --- Linear Solvers
+ sparse.linalg.dsolve.umfpack --- :Interface to the UMFPACK library:
+                                  Conjugate Gradient Method (LOBPCG)
+ sparse.linalg.eigen          --- Sparse Eigenvalue Solvers
+ sparse.linalg.eigen.lobpcg   --- Locally Optimal Block Preconditioned
+                                  Conjugate Gradient Method (LOBPCG)
+ spatial                      --- Spatial data structures and algorithms
+ special                      --- Special functions
+ stats                        --- Statistical Functions
+
+Utility tools
+-------------
+::
+
+ test              --- Run scipy unittests
+ show_config       --- Show scipy build configuration
+ show_numpy_config --- Show numpy build configuration
+ __version__       --- Scipy version string
+ __numpy_version__ --- Numpy version string
