Though it's an easy fix, I would hope it can still be treated with importance: there's a whole bunch of source code that has a wrong/outdate address for the Free Software Foundation.
The address in the source files are:
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
When the address should be:
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
By my counts there's a least 50 incorrect files.
By the way, I like what I'm seeing! Keep up the good work! :)
