-#
-# This is the replacement for the rev_db format, which was too big
-# and inefficient for large repositories with a lot of sparse history
-# (mainly tags)
-#
-# The format is this:
-# - 24 bytes for every record,
-# * 4 bytes for the integer representing an SVN revision number
-# * 20 bytes representing the sha1 of a git commit
-# - No empty padding records like the old format
-# (except the last record, which can be overwritten)
-# - new records are written append-only since SVN revision numbers
-# increase monotonically
-# - lookups on SVN revision number are done via a binary search
-# - Piping the file to xxd -c24 is a good way of dumping it for
-# viewing or editing (piped back through xxd -r), should the need
-# ever arise.
-# - The last record can be padding revision with an all-zero sha1
-# This is used to optimize fetch performance when using multiple
-# "fetch" directives in .git/config
-#
