just missing files but files that differ between the trunk and release. Some of these are going to be bug fixes that haven't been merged, some of them are ongoing development that isn't ready for release. Some of it is just my script being picky; since (for example) $Date will get expanded by SVN, and that shows up as a difference, too. -- Marshall
