The code is below.

1. Put that in a file into your local_files/lib (must have a .php extension)
2. browse to http://your_site/?update=1
3. browse to http://your_site/media/files/submitremote

To hook up a submit form (you won't get all the features like
'suggested tags' without hacking sorry):

1. click Manage Site
2. click Submit Forms
3. click 'Add new form type'
4. Fill out the form (about half don't apply, again, sorry)
   4a. In "Handler URL" put: 'files/submitremote'

That's it.

The code below needs LOTS of testing for various conditions and way
better error handling. Works great as long you have a direct link

http://example.com/groovy.mp3

probably breaks on cases without a proper extension
