Creative Commons GNU GPL

The CC-GNU GPL adds the Creative Commons' metadata and Commons Deed to the Free Software Foundation's GNU General Public License. The license is the official FSF GPL, and includes a Portuguese translation.

To signal to others that you are using a Creative Commons license, you can use a Creative Commons logo, which links to the CC-GNU GPL. The result will look like this:

This software is licensed under the CC-GNU GPL version 2.0 or later.

Human-Readable Commons Deed	Lawyer-Readable Legal Code	Machine-Readable Digital Code

Here's how the CC-GNU GPL works: A user clicking on the Creative Commons icon gets the CC-GNU GPL "Commons Deed" — a human readable version of the license. From that she can link to "Legal Code" — the full text of the GNU GPL, in English and Portuguese. And hidden in the tag is "Machine-Readable Code" — metadata — that will enable others to find your software.
