Thank you. It works now. I had figured out how to take command line
arguments, but needed the atoi() function to finish this off.

shell> vi usleep.c

int main(int argc, char** argv) {
  if ( argc > 1 )
    usleep(atoi(argv[1]));
}

shell> make usleep
shell> cp usleep /usr/local/bin/
shell> usleep 250000 # sleep for a quarter second

Now my system has usleep on it!! Awesome, that was fun.
