One minor correction: the system() function is part of the C language
definition, so it should exist on any system that supports C,
not just Unix.

On the other hand, the form of the argument to system() is extremely
system-specific.  On Unix, it's usually passed to /bin/sh, on
DOS/Windows, I think it's usually interpreted as a DOS command,
and so on.
