	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.

	Alternatively, individual users can add the following command:

	(require 'site-gentoo)

	to their ~/.emacs initialisation files, or, for greater flexibility,
	users may load single package-specific initialisation files from
	${SITELISP}/site-gentoo.d/.

		Starting with emacs-23.3-r3, the location of the site startup
		file for Emacs has changed to /etc/emacs/site-start.el. If your
		site-start file contains your own customisation, then you should
		move it to the new file. In any case, you should remove the old
		${SITELISP}/site-start.el file.
