Gimme a break Fred, this is net.unix, people can ask questions like
this.

Besides, how does your pseudocode handle the -r option? And permissions?
And multiple file names to a directory? And the -i option? And checking
for copying a file to itself (hint: it works with links)? Cp isn't
very hairy, but it's a lot hairier than that.

Egad! You don't work for DEC, do you?

That's right, I guess the rest will be in the "next release"...
