Please make sure, whatever alternate upload announcement format you design, that it is machine-readable so that it can be used to (at least partially) automate the FTP site administration process. The format should state in an unambiguous-to-parse fashion the names of all files uploaded, the size and MD5 checksum of the files, and the expected destination of those files. I'd like it to be possible to at least partially automate the FTP archive-management process and to audit the FTP site using the package-announcement files.
Having the input script for the debian-changes mailing list translate the machine-readable upload announcement to something more human-readable might be a desirable feature. Thanks Bruce
