 I'm rewriting the Python detection to use a loop and run through a list of
 python versions which easier to extend with future Python releases and
 less error-prone than the current one-liner.

 During the rewrite i stumbled upon
 {{{
 # Use python2 if the checks that use "command" fail
 ${PYTHON:=python2} -m chutney.TorNet "$@
 }}}
 which is at the end of the chutney shell script. I believe this isn't
 going to work if the previous command checks didn't find `python2`
 already. Isn't it better to display an error message and abort further
 execution of Chutney?
