For Python, I remember docopt (<a href="http:&#x2F;&#x2F;docopt.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;docopt.org&#x2F;</a>) being a big deal for a while - never used it, but sounds much nicer than writing out lots of code to construct your options parsing. Any reason why groper is a better option?
