DOC_CONTENTS="All site initialisation for Gentoo-installed packages is
added to ${SITELISP}/site-gentoo.el. In order for this site
initialisation to be loaded for all users automatically, a default
site startup file /etc/emacs/site-start.el is installed. You are
responsible for maintenance of this file.
\n\nAlternatively, individual users can add the following command:
\n\n(require 'site-gentoo)
\n\nto their ~/.emacs initialisation files, or, for greater
flexibility, users may load single package-specific initialisation
files from the ${SITELISP}/site-gentoo.d/ directory."
