description         The machine-learning toolbox's focus is on large-scale \
                    kernel methods

long_description    ${description} and especially on Support Vector Machines \
                    (SVM). It provides a generic SVM object interfacing to \
                    several different SVM implementations, among them the \
                    state of the art OCAS, LibSVM, SVMLight, SVMLin and GPDT.
