It starts like this: "Permission to use, copy, modify, and distribute this software and its documentation with or without modifications and for any purpose and without fee is hereby granted" Does the provision "without fee" make it non-free? Otherwise, I think you could use "non-copyleft" (which takes additional arguments just like "x11-style"). Andreas
