autoreply and insert blurb before body

I am looking for a recipe that will return the message to
the sender and insert a few lines before the body of the 
original message. I have found the example of how to
add content after the original message, but I want to
add a blurb _before_ the original message. I have read
the docs but I must be missing something.


Thanks in Advance,
