usage: mkdirp [DIR1,DIR2..] {OPTIONS}

Create each supplied directory including any necessary parent directories
  that don't yet exist.

If the directory already exists, do nothing.

OPTIONS are:

-m<mode>       If a directory needs to be created, set the mode as an octal
  --mode=<mode>  permission string.

-v --version   Print the mkdirp version number

-h --help      Print this helpful banner

-p --print     Print the first directories created for each path provided

--manual       Use manual implementation, even if native is available
`
