2755 # modules, but I'm not sure which is most portable...
2756 #
2757 # This is the replacement for the rev_db format, which was too big
2758 # and inefficient for large repositories with a lot of sparse history
2759 # (mainly tags)
2760 #
2761 # The format is this:
2762 # - 24 bytes for every record,
2763 # * 4 bytes for the integer representing an SVN revision number
2764 # * 20 bytes representing the sha1 of a git commit
2765 # - No empty padding records like the old format
2766 # (except the last record, which can be overwritten)
2767 # - new records are written append-only since SVN revision numbers
2768 # increase monotonically
2769 # - lookups on SVN revision number are done via a binary search
2770 # - Piping the file to xxd -c24 is a good way of dumping it for
2771 # viewing or editing (piped back through xxd -r), should the need
2772 # ever arise.
2773 # - The last record can be padding revision with an all-zero sha1
2774 # This is used to optimize fetch performance when using multiple
2775 # "fetch" directives in .git/config
2776 #
2777 # These files are disposable unless noMetadata or useSvmProps is set
