% \begin{abstract}
% The version 0.4 of \texttt{cclicenses} is my very first attempt to write a
% package to submit to CTAN. It is intended for typesetting the \CC\
% licenses icons, using \LaTeX\ instead of defining new strokes by \MF.
% \end{abstract}
%
% \section{Introduction}
% Some journal and magazines started publishing articles released under free
% licenses, such as \CC. To show this fact immediately they want to insert the
%  proper logos
% along with the articles. Artists who release music, images or other
% work under \CC may want to add the proper icons to their documents as well.
%
% Some of these magazines, including the one I work for, are typeset by
% \LaTeX. So, I believe there's a need to instruct \LaTeX\ to typeset such
% logos.
%
% This is my very first attempt.
% All of the icons are typeset in boldface Helvetica. I used |\textcircled{}|
% to surround symbols by a circle. For some reason, the circle is not quite a
% circle when the text is very small or it's |\textbf|'ed.
%
% As I said, this is only my first attempt. Please do send me your suggestions
% to improve the result.
%
% \section{How to use the package's commands}
% It coulnd't be easier: according to the license you're going to release
% your work under, use the corresponding logos.
%
% \begin{table*}[h]
% \centering
% \caption{What command generates what icon}
% \begin{tabular}{lcl}
% \toprule
% \textbf{Command}&amp;\textbf{Icon}&amp;\textbf{License's type}\\
% \midrule
% |\cc|&amp;\cc&amp;Creative Commons\\
% |\ccby|&amp;\ccby&amp;Attribution\\
% |\ccnc|&amp;\ccnc&amp;NonCommercial\\
% |\ccnd|&amp;\ccnd&amp;NoDerivs\\
% |\ccsa|&amp;\ccsa&amp;Share-alike\\
% \bottomrule
% \end{tabular}
% \end{table*}
%
% \section{\CC\ licenses}
% When an artist wants to release his or her work under a free license, s/he
% can choose to adopt one of the \CC\ licenses.
%
% The CC licenses are used to reserve some rights to the author, give away
% some other rights, while the copyright is still held by the author.
%
% Since version 2.0, each license includes the \emph{Attribution} right which
% forces every person (who is not the author) to give the original author
% credit.
%
% A \emph{NoDerivs} icon, where ``NoDerivs'' stands for ``Non derivative
% works'', indicates that you may not alter, transform, or build upon a work;
% the \emph{NonCommercial} icon indicates that the work can't be used for
% commercial purposes. The \emph{Share-alike} icon, that applies only to
% derivative works ---so it can't appear along with the NoDerivs icon---, 
% forces to release the derivative works under the same license as the 
% original.
%
% \section{The current licenses}
% The following are the currently used licenses and the related commands:
%
% \begin{center}
% \begin{tabular}{lll}
% \toprule
% \textbf{Command}&amp;\textbf{License}&amp;\textbf{Symbol(s)}\\
% \midrule
% \multicolumn{3}{c}{Version 2.0}\\

% |\byncsa|&amp; Attribution-NonCommercial-ShareAlike&amp;\byncsa\\

% \bottomrule
% \end{tabular}
% \end{center}
%
% \section{Known issues}
% As already stated, this package uses the Helvetica font. Be sure it's
% installed in your system.
%
% The strokes are not so elegant. I advice not to use them when typesetting
% |\tiny| and |\scriptsize| text.
%
% The ``NonCommercial'' and ``Share-alike'' logos are just usable, not exactly
% good-looking. I hope I'll be able to release a new version of this package
% soon,  where I use the |picture| environment instead of
% the |\textcircled| command.
%
% The space after the icons is wrong: it's always too big (it's not as big
% while using ``Share-alike'').
