SCM Exception

An extension to the GNU family of open source licences that is meant to ensure that developers can create executables From GPL'd versions of the code while the source code remains under the GPL licence, in other words you can give or sell the executables created with the software under any conditions you like but the source code remains GPL'd and any additions to it by default become GPL. Commonly used with the GNU GPL v2 Licence and less commonly with the GNU GPL v3 Licence.

Disclaimer
Note that the licence text below is here for reference purposes and unlike other material on the EDM/2 Wiki is not under the Attribution-ShareAlike 3.0 licence and should be treated under its own terms, or if an addition by the combined terms of the addition and the licence that it is an addition to. As it is a licence with fixed terms the text below it should not be modified except for formatting purposes, if a more recent version is published a new page should be created for that licence since software packages that do not get updated will continue to be governed by the terms of the older licence.

Text of exception
As a special exception, the Free Software Foundation gives permission for additional uses of the text contained in its release of SCM.

The exception is that, if you link the SCM library 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 SCM 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 Free Software Foundation under the name SCM. If you copy code from other Free Software Foundation releases into a copy of SCM, 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 SCM, it is your choice whether to permit this exception to apply to your modifications. If you do not wish that, delete this exception notice.
