Auto Format - documentation / options - where ?

After much googling I still cannot find
a) What is name of the software / convention used in /by AutoFormat - something about "art".
I just forgot, OF senior moment
b) What is the name / location of the autoformat options? Preferemces.txt??
I want to set - "remove blank lines"

Thanks for reply.

I don't think that that's an option. Actually, I didn't think you could change anything other than the indent size.
