Today I learnt a great tip [Steve Purcell](https://github.com/clojure-emacs/nrepl.el/issues/382][here]] via [[http://www.sanityinc.com/). If you want to get the absolute latest build of an Emacs package, without waiting for the MELPA rebuild cycle to take place, just:
recipes/file in emacs.
M-x package-build-current-recipeto evaluate that recipe locally and install the latest package.
I must remember that one...
