Dear David ,
	in all cases of command line line redirection, the file assignments
are changed by the shell, not by the program. The program does not
know where its input comes from nor where its output goes, so long as
it uses file 0 for input and 1 and 2 for output. See K&R (2nd edition)
7.1 and 8.1 for further details.
