%description
SVM (Support Vector Machines) is a powerful learning machine algorithm
for classification an regression problems.

Libsvm is a simple, easy-to-use, and efficient software for SVM
classification and regression. It can solve C-SVM classification,
nu-SVM classification, one-class-SVM, epsilon-SVM regression, and
nu-SVM regression. It also provides an automatic model selection
tool for C-SVM classification.
