it's possible to make a variant of "script" for plan 9 without using
any special purpose programs at all:

% > conslog
% chmod +a conslog
% pipefile -r 'tee conslog' -w 'tee conslog' /dev/cons
% rc < /dev/cons > /dev/cons >[2] /dev/cons

only slight problem seems to be that it doesn't exit when you type EOF.
a small price to pay.
