6This file is executed two ways:: 

7 

8 $ coverage run try_execfile.py 

9 

10and:: 

11 

12 $ python try_execfile.py 

13 

14The output is compared to see that the program execution context is the same 

15under coverage and under Python. 

16 

17It is not crucial that the execution be identical, there are some differences 

18that are OK. This program canonicalizes the output to gloss over those 

19differences and get a clean diff.
