Yes it does. It places the analysis in a dmp file. You will have to turn
logging on to have write to the dump file. Analysis can done to either a game
file or an epd file.
I've included a sample of a Shredder 3 dump file. I haven't looked in detail
but I believe the Shredder 4 dump file is the same, maybe minor differences. I
have written an awk script to reformat the output from an epd analysis (sample
below) back to standard epd format.
