Licensing for QScintilla examples

Hi Phil!

While updating QScintilla package for Debian I noticed that files in
example-Qt4Qt5/ have the following license statement:

** Licensees holding a valid Qt License Agreement may use this file in
** accordance with the rights, responsibilities and obligations
** contained therein.  Please consult your licensing agreement or
** contact [email protected] if any conditions of this licensing
** agreement are not clear to you.

Does this mean that they are for commercial Qt customers only? Is it
possible to explicitly specify an open source license under which they
can be distributed?
