Hey, By playing with a word list today I noticed I can't compute the number of average letters / word by simply doing a calc `wc -m file`/`wc -l file` because the filename is part of the output if wc is run on a file (on stdin it is suppressed). This is why I added a new flag -q so that a user can suppress that part of the output I will. I don't have high hopes of it getting accepted, but I said I try :)
Cheers, Tom
