This folder is for conversion of scripts from Python2 to Python3.
The goal is to use constructs that are acceptible in both Python 2 and Python 3.

We start by doing an automated conversion:

2to3 scriptname.py

just prints diffs, without changing the script.

2to3  -w scriptname.py

prints diffs and changes the file.

Lines like

@@ -76,7 +76,7 @@

indicate that changes begin at line 76, and go for 7 lines. 
- refers to the original file, + refers to the modified file.
