       -j [jobs], --jobs[=jobs]
            Specifies  the  number of jobs (commands) to run simultaneously.  If there is more than
            one -j option, the last one is effective.  If the -j option is given without  an  argu-
            ment, make will not limit the number of jobs that can run simultaneously.
