	The "\n" of "\nyer" is escaped as a new line. That's a Bad Thing. In 
fact, relying on backslashes being automatically escaped thanks to the 
following character not having a special meaning in escape context is a 
Bad Thing.
	Either way, it's better to use forward slashes (or os.sep if you're 
going for overkill and/or obscure, non-POSIX platforms), with which 
such problems just don't happen.
