To keep my configuration -consistent across all of them, I do what many people do and made the -`~/.emacs.d` directory a -[git repository](https://github.com/davexunit/.emacs.d). I don’t like -to keep copies of all of the Elisp extensions that I use, such as -paredit and geiser, in this repository. Instead, I prefer to use -package.el (introduced in Emacs 24) with the -[MELPA](https://melpa.org) repository. This saves me from having to -manually keep all of the extensions I use up-to-date, but requires -another method to keep useful packages in sync between computers. - -There’s a project called -[Pallet](https://github.com/rdallasgray/pallet) that solves this -problem, but it was too heavy for my liking.

Note that before calling -`install-missing-packages` you must have already initialized the -package manager via the `package-initialize` function. This approach -does require some manual bookkeeping in order to keep the -`required-packages` list up-to-date with your workflow, but I haven’t -found it to be problematic. - -Update: If this solution is too simplistic for you, you should check -out [use-package](https://github.com/jwiegley/use-package), which -reddit user [lunayorn](http://www.reddit.com/user/lunaryorn) pointed -out to me.
