Source code (graham.c for gra_print_stats and robinson.c for
rob_print_stats).

Say an MUA has a field where you can enter any pre-processing utililty.
Then there are special values like %f (file where MUA puts the mail) or
%F (file where MUA expects the mail for reading back in and replacing).
This does not support stdio. Therefore you need the switches -I and -O
in order to be able to write something like:

    bogofilter -p -I %f -O %F

Such a line is exec'ed or system'ed or whatever call the language
provides in order to support starting external programs. Not every
language a MUA could be written in may support stdio redirection in a
call to exec/system/whatever, so that the above syntax must be used.
