If I undertand correctly what you want your program is going to  
explicitly output pairs "\r\n".

If that's the case, in addition to the recommendation about IO#print  
already given take into account that the io needs binmode. Otherwise,  
on CRLF platforms you'd end up with "\r\r\n" on disk, which would be  
wrong. That's because the single "\n" in "\r\n" gives itself a pair  
"\r\n" in text mode. So IO#print CRLF in binmode is the complete  
portable solution.
