This package was initially debianized by Torsten Werner and is now maintained by Soeren Sonnenburg . The nonfree SVMlight files have been removed from the upstream archive. Users seeking for SVMLight may resort to using the included GPDT-SVM as a drop in replacement. It uses a very similar algorithm but in many practical applications was shown to be a lot faster. User documentation is available if the shogun-doc package is installed. Just point your browser to /usr/share/doc/shogun-doc-en/html-en/index.html .
