According to the man page (for 3.8.2):
--help,-help,-usage,-h,-H,/?
Print usage information and exit.
Usage describes the basic command line interface and its options.
And I saw this behavior, without removing the -H option no build direcotry was
created and ninja failed complaining "no such directory build"
