If you specify the only -c switch, el output one S-exp by one line of stdin. --a n --args n Specifies the maximum number of arguments of a Elisp function with -c switch. -f fmt --format fmt Allows you to use format string of printf for making a S-exp. -x --execute Requests to Oneliner to evaluate the S-exp to use *Oneliner auto-eval* buffer. -i buf --inpipe buf Gets input from pipe-buffer.
