[Fsfe-france] Licensing question about a compiler

        CherryPy is a compiler that generates python code
(http://www.cherrypy.org/). It is currently under the GNU GPL,
including the parts that are output in the generated python source
code. The authors of CherryPy would like to change the licence of the
*output* of CherryPy so that it is covered by a permissive license, in
the same way Bison or Flex do.

        The problem is that the output of CherryPy that comes from
CherryPy is tightly mixed with the code written by the user of the
compiler. This output ranges from tiny pieces of code to entire
functions. For instance, a 20 lines input may generate a 1000
lines output.

        The solution I suggested is to include a permissive licence
notice in the generated file(s) with an information notice that
clearly states that this licence only covers the parts that are copied
or derived from the CherryPy source.

        I'd very much like your input and, if the solution is not
problematic for some reason, a proper english wording of the
information notice.

        Thanks in advance for your help,
