+# @BLURB: Eclass for Emacs Lisp packages
+# @DESCRIPTION:
+#
+# This eclass sets the site-lisp directory for Emacs-related packages.
+#
+# 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: DOCS
+# @DESCRIPTION:
+# DOCS="blah.txt ChangeLog" is automatically used to install the given
+# files by dodoc in src_install().
+
+# @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.
