+Getting lexer names
+-------------------
+
+*New in Pygments 1.0.*
+
+The ``-N`` option guesses a lexer name for a given filename, so that ::
+
+    $ pygmentize -N setup.py
+
+will print out ``python``.  It won't highlight anything yet.  If no specific
+lexer is known for that filename, ``text`` is printed.
