Fine, my toy example will still be applicable.  But, you know, you 
haven't told us enough to give you help.  Do you want to replace text 
from values in a file?  That's been covered. Do you want to send the 
messages using those libraries?  You haven't said what you don't know 
how to do.  Something else? What is it that you want to do that you 
don't know how?
