That's interesting.  The file I got from I not where returned strings.
 If you don't mind doing the conversion then you're more than welcome
to but you could download the version I use from my [GitHub
page](http://github.com/timvisher/.emacs/blob/master/site-lisp/emacs-type.el)
if you so desired.  Again, I had to override it like
[so](http://github.com/timvisher/.emacs/blob/master/lisp/platform-detection.el)
in order to correctly detect Macs.

If I were you I'd put it in my .emacs file.  That way it gets
evaluated for everything in the life of that emacs process.  This
works for me at least.  Here's a [very simple example of how I use
it](http://github.com/timvisher/.emacs/blob/master/lisp/my-config.el#L33).
