// This is the venerable .in ("input") file that needs some kind of
// preprocessing.
//
// One interesting aspect of this target type is that the prerequisite
// search is target-dependent. Consider:
//
// hxx{version}: in{version.hxx} // version.hxx.in -> version.hxx
//
// Having to specify the header extension explicitly is inelegant. Instead
// what we really want to write is this:
//
// hxx{version}: in{version}
//
// But how do we know that in{version} means version.hxx.in? That's where
// the target-dependent search comes in: we take into account the target
// we are a prerequisite of.
