# 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.
