-/* Options:
- -p, --parent Ensure that the given path(s) exist:
- Make any missing parent directories for each argument.
- Parent dirs default to umask modified by `u+wx'.
- Do not consider an argument directory that already
- exists to be an error.
- -m, --mode=mode Set the mode of created directories to `mode', which is
- symbolic as in chmod and uses the umask as a point of
- departure.
