    // 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.
