An earlier and unrelated scripting engine, named Qt Script for Applications (QSA), was shipped by Trolltech as a separate Qt-based library, dual-licensed under GNU General Public License (GPL) and a commercial license.
With the release of QtScript, QSA has been deprecated and reached its end of life in 2008.4
