; 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.
