        !            22: To get started
        !            23: simply type `learn'.
        !            24: The program will ask questions to find out what
        !            25: you want to do.
        !            26: The questions may be bypassed by naming a
        !            27: .I subject,

        !            30: number that
        !            31: .I learn

        !            35: number that was given with the lesson number

        !            37: .I learn
        !            38: places around the speed number).

        !            71: .SH BUGS
        !            72: The main strength of
        !            73: .I learn,
        !            74: that it asks the student to use the real
        !            75: UNIX, also makes possible baffling mistakes.
        !            76: It is helpful, especially for nonprogrammers,
        !            77: to have a UNIX initiate near at hand during the first
        !            78: sessions.
        !            79: .PP
        !            80: Occasionally lessons are incorrect, sometimes because the local version
        !            81: of a command operates in a non-standard way.
        !            82: Such lessons may be skipped,
        !            83: but it takes some sophistication to recognize
        !            84: the situation.
