+# @BLURB: Emacs-related installation utilities
+# @DESCRIPTION:
+#
+# Usually you want to use this eclass for (optional) GNU Emacs support
+# of your package.  This is NOT for XEmacs!
+#
+# Many of the steps here are sometimes done by the build system of your
+# package (especially compilation), so this is mainly for standalone
+# elisp files you gathered from somewhere else.
+#
+# When relying on the emacs USE flag, you need to add
+#
+# @CODE
+# 	emacs? ( virtual/emacs )
+# @CODE
+#
+# to your DEPEND/RDEPEND line and use the functions provided here to
+# bring the files to the correct locations.
+#
+# If your package requires a minimum Emacs version, e.g. Emacs 24, then
+# the dependency should be on >=virtual/emacs-24 instead.  Because the
+# user can select the Emacs executable with eselect, you should also
+# make sure that the active Emacs version is sufficient.  This can be
+# tested with function elisp-need-emacs(), which would typically be
+# called from pkg_setup(), as in the following example:
+#
+# @CODE
+# 	elisp-need-emacs 24 || die "Emacs version too low"
+# @CODE
+#
+# Please note that such tests should be limited to packages that are
+# known to fail with lower Emacs versions; the standard case is to
+# depend on virtual/emacs without version.
+#
+# @ROFF .SS
+# src_compile() usage:
+#
+# An elisp file is compiled by the elisp-compile() function defined
+# here and simply takes the source files as arguments.  The case of
+# interdependent elisp files is also supported, since the current
+# directory is added to the load-path which makes sure that all files
+# are loadable.
+#
+# @CODE
+# 	elisp-compile *.el
+# @CODE
+#
+# Function elisp-make-autoload-file() can be used to generate a file
+# with autoload definitions for the lisp functions.  It takes the output
+# file name (default: "${PN}-autoloads.el") and a list of directories
+# (default: working directory) as its arguments.  Use of this function
+# requires that the elisp source files contain magic ";;;###autoload"
+# comments.  See the Emacs Lisp Reference Manual (node "Autoload") for
+# a detailed explanation.
+#
+# @ROFF .SS
+# src_install() usage:
+#
+# The resulting compiled files (.elc) should be put in a subdirectory of
+# /usr/share/emacs/site-lisp/ which is named after the first argument
+# of elisp-install().  The following parameters are the files to be put
+# in that directory.  Usually the subdirectory should be ${PN}, you can
+# choose something else, but remember to tell elisp-site-file-install()
+# (see below) the change, as it defaults to ${PN}.
+#
+# @CODE
+# 	elisp-install ${PN} *.el *.elc
+# @CODE
+#
+# To let the Emacs support be activated by Emacs on startup, you need
+# to provide a site file (shipped in ${FILESDIR}) which contains the
+# startup code (have a look in the documentation of your software).
+# Normally this would look like this:
+#
+# @CODE
+# 	(add-to-list 'load-path "@SITELISP@")
+# 	(add-to-list 'auto-mode-alist '("\\.csv\\'" . csv-mode))
+# 	(autoload 'csv-mode "csv-mode" "Major mode for csv files." t)
+# @CODE
+#
+# If your Emacs support files are installed in a subdirectory of
+# /usr/share/emacs/site-lisp/ (which is strongly recommended), you need
+# to extend Emacs' load-path as shown in the first non-comment line.
+# The elisp-site-file-install() function of this eclass will replace
+# "@SITELISP@" and "@SITEETC@" by the actual paths.
+#
+# The next line tells Emacs to load the mode opening a file ending
+# with ".csv" and load functions depending on the context and needed
+# features.  Be careful though.  Commands as "load-library" or "require"
+# bloat the editor as they are loaded on every startup.  When having
+# many Emacs support files, users may be annoyed by the start-up time.
+# Also avoid keybindings as they might interfere with the user's
+# settings.  Give a hint in pkg_postinst(), which should be enough.
+# The guiding principle is that emerging your package should not by
+# itself cause a change of standard Emacs behaviour.
+#
+# The naming scheme for this site-init file matches the shell pattern
+# "[1-8][0-9]*-gentoo*.el", where the two digits at the beginning define
+# the loading order (numbers below 10 or above 89 are reserved for
+# internal use).  So if your initialisation depends on another Emacs
+# package, your site file's number must be higher!  If there are no such
+# interdependencies then the number should be 50.  Otherwise, numbers
+# divisible by 10 are preferred.
+#
+# Best practice is to define a SITEFILE variable in the global scope of
+# your ebuild (e.g., right after S or RDEPEND):
+#
+# @CODE
+# 	SITEFILE="50${PN}-gentoo.el"
+# @CODE
+#
+# Which is then installed by
+#
+# @CODE
+# 	elisp-site-file-install "${FILESDIR}/${SITEFILE}"
+# @CODE
+#
+# in src_install().  Any characters after the "-gentoo" part and before
+# the extension will be stripped from the destination file's name.
+# For example, a file "50${PN}-gentoo-${PV}.el" will be installed as
+# "50${PN}-gentoo.el".  If your subdirectory is not named ${PN}, give
+# the differing name as second argument.
+#
+# @ROFF .SS
+# pkg_postinst() / pkg_postrm() usage:
+#
+# After that you need to recreate the start-up file of Emacs after
+# emerging and unmerging by using
+#
+# @CODE
+# 	pkg_postinst() {
+# 		elisp-site-regen
+# 	}
+#
+# 	pkg_postrm() {
+# 		elisp-site-regen
+# 	}
+# @CODE
+#
+# When having optional Emacs support, you should prepend "use emacs &&"
+# to above calls of elisp-site-regen().
+# Don't use "has_version virtual/emacs"!  When unmerging the state of
+# the emacs USE flag is taken from the package database and not from the
+# environment, so it is no problem when you unset USE=emacs between
+# merge and unmerge of a package.
