The way I use printfck is to run my code through it, feed the result to lint
and then throw all this garbage away again. Code full of procent_x() calls
is good for lint but not for me when I want a nicely formatted listing.

People who not only like the idea but also want to actually use it may like
to know that guido at mcvax improved my version - ask him before you start
polishing printfck.c.
