The argument for that is that there are many > such manuals and they would be useful to include, and the DFSG can > be interpreted to accept it. The arguments appear to be: 1) There are many GFDL manuals. 2) The many GFDL manuals would be useful to include. That's two parts out of the three I mentioned, and the third part is crucial. The DFSG doesn't directly say anything against the requirements of the GFDL. I sent another longer message explaining why.
