Introduction

This is a fork of Laurens van der Maaten's implementation of the t-SNE algorithm. It adds a C interface to the original code and provides a more convenient command-line interface. The command-line tool now takes the SND format as input, where each data line consists of a sample name and a vector for the sample.
