3565 # - 24 bytes for every record,
3566 # * 4 bytes for the integer representing an SVN revision number
3567 # * 20 bytes representing the sha1 of a git commit
3568 # - No empty padding records like the old format
3569 # (except the last record, which can be overwritten)
3570 # - new records are written append-only since SVN revision numbers
3571 # increase monotonically
3572 # - lookups on SVN revision number are done via a binary search
3573 # - Piping the file to xxd -c24 is a good way of dumping it for
3574 # viewing or editing (piped back through xxd -r), should the need
3576 # - The last record can be padding revision with an all-zero sha1
