Python-digest # 12. News, interesting projects, articles and interviews [January 24, 2013 - January 31, 2014]

So again news about Python and nearby technologies. Today, a lot of interesting things about Wheels and packages in general, MoviePy, AI for games, Russian documentation on argparser and more.

Many thanks to those who sent news to the tool for creating digests and to those who helped to tie the domain pythondigest.ru to it ( inetava , vaal especially). He is now ours as
at least two and a half years. Thank you very much owlman for providing the illustration.

Discussion. It seems that recently the topic of packages of modules and their management very often pops up. Do you think the revolution will break out on this topic? Can someone offer a very handy tool that will replace pip and PyPI, or will Anaconda be revived? How do you organize work with packages in your company? What criteria are important for you in the package manager?
