<?php

////////////////////////////////////////
File : rnton.php
Description: Traverses through a specified
directory and converts all
occurances of rn to n,
in the specified type of
files.
Why? : We developed this since after
changing to the new version of
PhpEditor, most of our files
on the Linux machine were
showing double line spacing :)
