That is *not* stated in GPL 2. Section 9 states: "Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation." David K. wrote a program and it was "marked as GPL 2". This means he licensed it under GPL version 2. Section 9 above says "If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation." Since David *did* specify a version number, this latter statement does not apply. The former statement also doesn't apply, since he didn't write "any later version" explicitly in his license statement. -- William -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
