This change was not included in the previous commit because the sed
command I used included the `/usr/bin/env` path to ensure I don't
replace any occurences of the word `python` which I did not wish to
replace.
* It is now possible to test:
* Hook Input/Output on STDIN/STDOUT channels
* Exit code of hook script
* Execution count (how many times the hook was executed)
* Timestamp execution (when was the hook executed - milisec resolution)
