//  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.
