  20                         Make any missing parent directories for each argument.
  21                         Parent dirs default to umask modified by `u+wx'.
  22                         Do not consider an argument directory that already
  23                         exists to be an error.
  24    -m, --mode=mode      Set the mode of created directories to `mode', which is
  25                         symbolic as in chmod and uses the umask as a point of
  26                         departure.
