I wondered that also but I think they meant that their preprocessor
can treat even non parsable input. For exemple, in C, if your input
is:
      /* main () { printf("hello, world"); }

It is not parsable since the comment does not end, but if your
preprocessor is:
      sed -e 's|/\*||'

Which removes the initial /*, the C compiler can parse.

Camlp4 is a preprocessor which parses, respecting a "grammar" (it's
why they say "grammar-based"), what sed or /lib/cpp don't really do:
they just look at what is interesting for them, even if the rest is
not correct C.

Well, it is the way I interpreted what they said.
