where to find scripts

I inadvertently deleted my archived version of the default digest 
script.  My "improvements" to the script now result in a digest full of 
"Unidentified Subject" topic lines and no posts, so I would like to start 
over and try again.  I looked through the documentation, but can't find any 
reference to a site that has the original Smartlist scripts.

I have flush_digests working correctly, but was trying to modify the digest 
script to make it plain text and to include another line between posts to 
make it look better.  Seems simple enough following the documentation, but 
I must have introduced a renegade character somewhere along the way and I'm 
having some trouble deciphering the log to reveal the problem.  So I'd like 
to start over with the default script.

thanks,

Linda
