Emacs package management

EDIT 2023-01-06: Nowadays, there is use-package. I recently tried to install MuMaMo as one of the dependencies for Takafumi Arakaki’s Emacs-based IPython notebook. The instructions on the MuMaMo webpage were as clear as mud and aimed primarily at Windows users. Enters apt-get for Emacs! My Emacs setup is shared across multiple machines: a synchronized elisp folder, containing *.el files, along with my .emacs configuration. el-get allows you to share your package installation folder in a similar fashion.
