This program is "Libre" Software. I like the spanish word "libre" more than english one "free", because it is "free of freedom, not free like free beer", as Richard Stallman said.

You can share it and/or modify it under the GNU General Public License, like it has been published by the Free Software Foundation; as the version 2 like, at your choose, any later version.

At the end of this document there will be an apendice with the full license.
