All,   
      
   Realize there may be similar things out there but this is what I wrote.  It   
   assumes your message base file name is the same as your echo tag. It is   
   embedded in my processing logic.   It will create a unique list of output   
   echoes to scan.   
      
   The python may not be elegant but I have only been writing python for less   
   than a week.  If you have suggestions please provide them!
