Don't do this.  The problem is that you may run into a URL that maybe
looks something like this (do not enter this on your shell as I haven't
tested to make sure it's safe):

  http://www.example.com/index.html&echo'%20rm%20-fr%20/'

This is something that we've talked about on the development mailing
list but just haven't gotten around to fixing yet.  The idea is to
quote the variables so that it would be safe to source the .info file
right into your shell.
