  22 ;;;; The exception is that, if you link the GUILE library with other files
  23 ;;;; to produce an executable, this does not by itself cause the
  24 ;;;; resulting executable to be covered by the GNU General Public License.
  25 ;;;; Your use of that executable is in no way restricted on account of
  26 ;;;; linking the GUILE library code into it.
  27 ;;;;
  28 ;;;; This exception does not however invalidate any other reasons why
  29 ;;;; the executable file might be covered by the GNU General Public License.
  30 ;;;;
  31 ;;;; This exception applies only to the code released by the
  32 ;;;; Free Software Foundation under the name GUILE.  If you copy
  33 ;;;; code from other Free Software Foundation releases into a copy of
  34 ;;;; GUILE, as the General Public License permits, the exception does
  35 ;;;; not apply to the code that you add in this way.  To avoid misleading
  36 ;;;; anyone as to the status of such modified files, you must delete
  37 ;;;; this exception notice from them.
  38 ;;;;
  39 ;;;; If you write modifications of your own for GUILE, it is your choice
  40 ;;;; whether to permit this exception to apply to your modifications.
