    -- Sample output:

    -- This PDF file contains a famous quote from William Shakespeare's "Romeo and Juliet". The quote appears twice on the page:
    -- 
    -- "These violent delights have violent ends
    -- And in their triumph die, like fire and powder,
    -- Which as they kiss consume. The sweetest honey
    -- Is loathsome in his own deliciousness
    -- And in the taste confounds the appetite.
    -- Therefore love moderately; long love doth so;
    -- Too swift arrives as tardy as too slow."
    -- 
    -- The file also includes a portrait image of William Shakespeare. This particular quote is spoken by Friar Lawrence in the play, warning about the dangers of passionate, 
    -- immoderate love - suggesting that love that burns too intensely tends to burn out quickly, just as fire and gunpowder consume each other when they meet.
