Both of these reasons are arguments for keeping the documentation
IN the code; If it's a separate file, the designer may forget that
it's even there (particularly on a group development effort like
Linux) and thus not update the code (the whole idea of having one
person write the code and another person document it is, well, an
unexpected refugee from the IBM mainframe world in the 1970s.)

The source is 8mb (compressed) already, and this includes

david parsons \bi/ code and primary documentation in separate files?
