+#!/usr/bin/env python
+'''
+Run this script inside of src/ and it will look for all the files
+that were changed this year that still have the last year in the
+copyright headers, and it will fix the headers on that file using
+a perl regex one liner.
+
+For example: if it finds something like this and we're in 2014
+
+// Copyright (c) 2009-2013 The Bitcoin developers
+
+it will change it to
+
+// Copyright (c) 2009-2014 The Bitcoin developers
+
+It will do this for all the files in the folder and its children.
