-       , ("contents", contents(path))

-     attrs((a, b)) = encS(a) + encS(b)
-
-     encS(s) = encN(len(s)) + s + (padding until next 64-bit boundary)
-
-     encN(n) = 64-bit little-endian encoding of n.
-
-     contents(path) = the contents of a regular file.
-
-     sort(strings) = lexicographic sort by 8-bit value (strcmp).
-
-     entries(path) = the entries of a directory, without `.' and
-     `..'.
-
-     `+' denotes string concatenation. */
