+# @BLURB: Eclass for Emacs Lisp packages
+# @DESCRIPTION:
+#
+# This eclass is designed to install elisp files of Emacs related
+# packages into the site-lisp directory. The majority of elisp packages
+# will only need to define the standard ebuild variables (like SRC_URI)
+# and optionally SITEFILE for successful installation.
+#
+# Emacs support for other than pure elisp packages is handled by
+# elisp-common.eclass where you won't have a dependency on Emacs itself.
+# All elisp-* functions are documented there.
+#
+# If the package's source is a single (in whatever way) compressed elisp
+# file with the file name ${P}.el, then this eclass will move ${P}.el to
+# ${PN}.el in src_unpack().
+
+# @ECLASS-VARIABLE: NEED_EMACS
+# @DESCRIPTION:
+# If you need anything different from Emacs 21, use the NEED_EMACS
+# variable before inheriting elisp.eclass.  Set it to the major version
+# your package uses and the dependency will be adjusted.
+
+# @ECLASS-VARIABLE: ELISP_PATCHES
+# @DESCRIPTION:
+# Any patches to apply after unpacking the sources. Patches are searched
+# both in ${PWD} and ${FILESDIR}.
+
+# @ECLASS-VARIABLE: SITEFILE
+# @DESCRIPTION:
+# Name of package's site-init file.  The filename must match the shell
+# pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are
+# reserved for internal use.  "50${PN}-gentoo.el" is a reasonable choice
+# in most cases.
+
+# @ECLASS-VARIABLE: ELISP_TEXINFO
+# @DESCRIPTION:
+# Space separated list of Texinfo sources. Respective GNU Info files
+# will be generated in src_compile() and installed in src_install().
+
+# @ECLASS-VARIABLE: DOCS
+# @DESCRIPTION:
+# DOCS="blah.txt ChangeLog" is automatically used to install the given
+# files by dodoc in src_install().
