My Emacs config
This is an Emacs 24 setup based on Cask.
Bootstrap
brew install cask
cd ~/.emacs.d
cask install
For packages loaded from a local working copy instead of their elpa release, link them into cask; this is necessary after a major upgrade of emacs (e.g. 24.4 to 24.5):
cask link vitamined-mode-line ./lisp-devel/vitamined-mode-line
After these steps, everything should be OK.
