Why is it in 2?
Will change your patch ok?
It's in 2 because the dev thinks it good to be in 2. We need not 2 so we remove it. patch : I have shown it to the dev of the program he said, it's a good patch. I have shown it to my companion he also said it will be ok.
It's easy to read.
-#!/usr/bin/env python2 //the minus at the start of the line removes this
+#!/usr/bin/env python //the plus at the start of the line adds it.
The rest of the patch file comes from the program I used, a diff with some options. I found the howto on the web and asked confirmation about the way it has to go to 2 persons who I know for knowing some python.
