How to perform one versus one multi class classification using LIBSVM ?

I have a data set with 15 features and 10 classes. I am not able to understand how to perform one versus one multi class classification using LIBSVM. Does it require installation of additional files (other than libsvm package). From the documentation I understood that svm-train and svm-predict are used for multi class but when I use these commands,the matlab does not recognize them. Please correct me if I have misunderstood the procedure.
