import java.io.IOException;

/**
 * Class that copies stdin to stdout, as compained about as not being cleanly
 * writable in Java on Hacker News.
 * In real code, you would just write IOUtils.copy(System.in, System.out),
 * which does basically the same thing.
 * This does not catch any exceptions as a) this is just an "exercise" and
 * b) all we could do with them is pretty-print them. So let the runtime 
 * print them for you.
