He wants to automatically add proper #include statements as soon as you
use external functions. In practice, this would mean you wouldn't have
to write any #include statements at all, since they would be
automatically added as you write your code (and also removed again when
not needed anymore, although this would be more difficult to do). By
using CEDET's templating system SRecode, this could even be made
language independent. I don't think the usual templating systems can do
that.
