Perl using just "\n" is portable enough. Meaning, if it's an active-perl 
installation, it will match the windows style line termination. If its a UNIX 
perl, it will match the UNIX newline.
If you run a file made on a windows machine, and you try to match the new 
lines in a UNIX perl installation, it will work. I have not tested the case 
from UNIX to windows, I dont have a windows box handy.
