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.

One of the great tragedies of ancient history is that Helen of Troy
lived before the invention of the champagne bottle.
