We're discussing what constitutes "code not goverened by the terms of this license", so until that's settled you can't really use that phrase as justification for your argument. Note, for instance, that it makes no reference to "code that was not already governed by this license". Thus, we don't know from that statement whether additional code as part of a "Larger Work" is excluded by that statement. > > They explicitly state: "In such a case, You must make sure the > requirements of this License are fulfilled for the _Covered Software_." > So the requirements must be fullfilled for software under CDDL, and not > for "code not governed by the terms of this License" (code under BSD in > our case). The question here is whether code previously "not governed by the terms of this license" is now "governed by the terms of this license". As things currently stand, and with the ambiguous phrasing of the license, it appears to me that this issue cannot be definitively settled without a judicial decision (or alteration of the CDDL to clarify the matter). -- CCD CopyWrite Chad Perrin [ http://ccd.apotheon.org ] print substr("Just another Perl hacker", 0, -2);
