Inserting a Creative Commons Licence into a LaTeX document

I wrote a package for this as I used something similar as Raniere Silva and I wanted it a bit more clean :)

The package is called doclicense. Check out the following mini example:

\documentclass{article}
\usepackage{hyperref}
\usepackage[
    type={CC},
    modifier={by-nc-sa},
    version={3.0},
]{doclicense}
\begin{document}
\doclicenseThis
\end{document}

There is a package that do it for you (the documentation is only available in portuguese at the moment): https://gitorious.org/mundo-livre/creative-commons-licenses-for-latex.

For my documents I use the code below in the cover.

 \begin{tabular}{|p{.9\textwidth}|}
 \hline

 \end{center}\\
 \hline
 \end{tabular}

The ccicons LaTeX package provides a set of icons to represent the Creative Commons licenses. There are macros for each icon, as well as shortcuts that allow you to simply drop a specific set of license icons for a license type (e.g., \ccbyncsa will add the CC logo, the attribution icon, the noncommercial (in US dollars) icon, and the share-and-share alike icon)).

Icons are a PostScript Type 1 font, so they scale cleanly.
