RTEMS is free software; you can redistribute it and/or modify it under
terms of the GNU General Public License as published by the

later version.  RTEMS is distributed in the hope that it will be useful,

As a special exception, including RTEMS header files in a file,
instantiating RTEMS generics or templates, or linking other files
with RTEMS objects to produce an executable application, does not
by itself cause the resulting executable application to be covered
by the GNU General Public License. This exception does not
however invalidate any other reasons why the executable file might be
covered by the GNU Public License.
