on windows a new line is really 2 characters, carriage return and line  
feed. In unix it's 2-in-1. The idea is to convert them you need to  
replace the carriage return and line feed with a newline character.

if you don't know what \r or \n are you should most definitely do some  
rtfmming :)

Good luck :)
