Hey but this is dos2unix :-).

You can't read in text-mode just like that in a portable way, because
chomp! only chomps "\n".

If you can assume the program is gonna run only on Windows then the
solution is trivial: read in text-mode, and write in binary mode. No
chomping or gsubs needed, just read and write.

If the program has to be portable then you need to deal with the
spurious \015 that may come up.
