The Harbour Project Library Licence

An add-on to the GPL v2 used by the Harbour project for the libraries used in their compiler, but the exception given in the text allows users of the Harbour tools to create executable that are unencumbered by the "viral" part of the GPL even though the libraries themselves are under the GPL.

As a special exception, the Harbour Project gives permission for additional uses of the text contained in its release of Harbour.

The exception is that, if you link the Harbour libraries with other files to produce an executable, this does not by itself cause the resulting executable to be covered by the GNU General Public License. Your use of that executable is in no way restricted on account of linking the Harbour library code into it.

This exception does not however invalidate any other reasons why the executable file might be covered by the GNU General Public License.

This exception applies only to the code released by the Harbour Project under the name Harbour. If you copy code from other Harbour Project or Free Software Foundation releases into a copy of Harbour, as the General Public License permits, the exception does not apply to the code that you add in this way. To avoid misleading anyone as to the status of such modified files, you must delete this exception notice from them.

If you write modifications of your own for Harbour, it is your choice whether to permit this exception to apply to your modifications. If you do not wish that, delete this exception notice.
