Petr BaudisThis tool takes pack index on stdin and produces the list of indexed objects on stdout.
Very simple, but I've been always somewhat nervous that I cannot list all (even unreferenced) objects in a repository, and in a given pack in particular. The immediate use will be in the git-count-objects script, but I can imagine it being useful also in various troubleshooting situations.
