This is of course correct except for the `undocumented' claim. The `envp' has
been documented as the third argument to main() since the Pharaons (well, not
quite ;). Apparently AT&T UNIX even has a (documented) five-parameter main().
Besides, the `envp' argument is a recommended extension in ISO/ANSI C, so you
can hardly say that it's undocumented.
