(The contents are the same, as revealed by "gunzip -c emacs-22.2.tar.gz | md5sum".) This causes two problems: 1. The above checksum can not be used to verify the generated file. (This could be solved by also informing us of the MD5 checksum of the ungzipped file, but problem #2 below indicates this is probably not worth it.) 2. The emacs-22.2.tar.gz generated by xdelta will presumably not be usable as the basis for the next release. There are two different emacs-22.2.tar.gz files, and the one generated by xdelta is different. Presumably, the next xdelta patch will be generated using the standard one, so one will not be able to use xdelta to upgrade two versions in a row. I'm not sure what the solution to this is. It is important that the .tar.gz file generated by xdelta is the same as the .tar.gz file distributed by FTP, or there will be problems. -- Joe Wells
