\tutorialpartsplit{This tutorial}{This part of the tutorial} gives a

comprehensive explanation of the most popular Free Software copyright

license, the GNU General Public License (``GNU GPL'', or sometimes just

``GPL'') -- both version 2 (``GPLv2'') and version 3 (``GPLv3'') -- and

teaches lawyers, software developers, managers and business people how to use

the GPL (and GPL'd software) successfully both as a community-building

``Constitution'' for a software project, and to incorporate copylefted

software into a new Free Software business and in existing, successful

enterprises.
