Most of the files in DJB's original tarball are marked "public domain". There seems no doubt to me that DJB has in that way given permission to do anything to the files.
Were anyone else to write "You may distribute unmodified copies of the cdb package", it would be natural to assume that they intend that you may not distribute modified copies. But DJB is a man who is exceptionally careful with his wordings in such cases. He writes EXACTLY what he means. And as he does not actually forbid distribution of modified copies, he has not contradicted his public domain comments. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
