// 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.
