mxdev is a utility that makes it easy to work with Python projects containing lots of packages, of which you only want to develop some. It works on top of stable constraints and uses the power of pip and git. You learn: - why we need it/ what problems it solves, - how it is used in your day to day work (based on Plone Backend), - how it compares to zc.buildout - how to extend it, - the current state of development and what our future plans are. Planned are 20 min talk and 10 min Q&A - prepare your questions!
