not ready for prime time

adj. 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 flavor for hackers because of the special (though now
semi-obsolescent) meaning of prime time. Compare beta.
