stderr is the file descriptor to which
annoying programmers dump the default output of a program when the output is longer then the screen, or when you want to use the program in a
script, or when you want to
capture the output to a file, or when they took
programming classes at
a crappy school, or when they
suck, or when you hate them or when you
KILL them or when...
Oh, sorry... That was
getting out of hand...
