description         A free Support Vector Machine implementation

long_description    {*}${description} By Chih-Chung Chang and Chih-Jen Lin of    \
                    National Taiwan University. \"LIBSVM is an integrated        \
                    software for support vector classification, (C-SVC, nu-SVC), \
                    regression (epsilon-SVR, nu-SVR) and distribution estimation \
                    (one-class SVM). It supports multi-class classification.\"
