Dos2Unix file formater

Description: I hate DOS \r\n (carriage return, newline) file formats. Each line is all broken and crappy. So, I hacked up this little guy for my unix boxen around the world.
# convert a dos \r\n format to unix \bn
open (FILE, $ARGV[0]);
while (<FILE>) {
        # remove the stupid \r, replace with \n
        # some broken editors just put \r
        # Remove the duplicate \n
Couple comments:
This thing just dumps the data back to the screen. You need to capture it yourself. It is a preference for me because I many times don't want to overwrite the file I am editting. If you don't like this, change it.
Secondly, this thing does some crazy stuff. I hate blank lines. This thing makes sure there are none. Have code you want formatted nicely? It will break it in a manner that only vroom could understand. So, its quick N dirty to the max.

Update Chromatic offered an easier way to do this. In fact I am sure that is the better way to do it, and in fact at some point it was written similar to that. The hell if I rememeber why I changed it. But it basically came down to its origins and the fact I didn't want ANY blank lines.

    Why not reduce that to: tr/\r\n/\n/s; Ahh, tr///!
