It'd probably be good to restrict this.  Zero is, technically, a valid
port, but its seen various uses over time / different OS.

If the manual page does not specify this, then this is up to you.

Think about what would be desirable from the user's point of view.  What
would make sense from the principle of least surprise?

This is up to you - again, think about what makes the most sense.

Note that it may be reasonable to have it go either way, depending on
the reason you're printing the usage:

If the user explicitly asks for the usage by passing '-h', then stdout
would make sense.  If the user provides illegal options, then stderr
would make sense.

See what other standard unix tools do and make your own choice.

You don't need to implement logging as part of HW#4.  That would make
more sense to be included in the final project.
