description         Easy-to-use and general-purpose machine learning in Python

long_description    Scikit-learn integrates machine learning algorithms \
                    in the tightly-knit scientific Python world, building upon \
                    numpy, scipy, and matplotlib. As a machine-learning module, \
                    it provides versatile tools for data mining and analysis \
                    in any field of science and engineering.
