Functions, mostly - the big `awk` command in the example goes into something like

    # @param $1 whatever
    chess_extract_scores() {
         awk blah blah blah
    }

and then your whole pipeline simplifies to

    cat foo | grep bar | chess_extract_scores

which is pretty readable. You can even do most of this in a live bash session with ^X ^E.
