From 57d4c86b2bd86be5811b35fc4ccaf653e7939e0e Mon Sep 17 00:00:00 2001
From: Roman Donchenko <roman.donchenko@itseez.com>
Date: Thu, 11 Apr 2013 18:34:04 +0400
Subject: [PATCH] Fixed the shebang lines on the Python scripts.

Also, removed the one from modules/python/src2/cv.py and cleared its
executable bit, since it's not a script.
