   As a special exception, the authors of SANE give permission for

   additional uses of the libraries contained in this release of SANE.

 |

   The exception is that, if you link a SANE 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
 |

 | 
						|
   account of linking the SANE 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.

 |

   If you submit changes to SANE to the maintainers to be included in
 | 
						|
   a subsequent release, you agree by submitting the changes that
 | 
						|
   those changes may be distributed with this exception intact.
 | 
						|
   
 | 
						|
   If you write modifications of your own for SANE, it is your choice
 | 
						|
   whether to permit this exception to apply to your modifications.

   If you do not wish that, delete this exception notice.
