not ready for prime time
     
        Usable, but only just so; not very robust; for internal use
        only.  Said of a program or device.  Often connotes that the
        thing will be made more solid {Real Soon Now}.  This term
        comes from the ensemble name of the original cast of "Saturday
        Night Live", the "Not Ready for Prime Time Players".  It has
        extra flavour for hackers because of the special (though now
        semi-obsolescent) meaning of {prime time}.  Compare {beta}.
