Well, if I'm going to be the Great Decider on this then I can say upfront I'm taking a pragmatic view of preferring open but not mandating it, preferring hg over git but not ruling out a switch, preferring Python-based tools but not viewing it as a negative to not use Python, etc.
(and you've later clarified that these will all be factors weighing in favour of a candidate.) Thanks for expressing your thoughts. Big thanks for taking on the role of consulting, evaluating, and deciding on this issue. -- \ “I think Western civilization is more enlightened precisely | `\ because we have learned how to ignore our religious leaders.” | _o__) —Bill Maher, 2003 | Ben Finney
