7# This eclass sets the site-lisp directory for emacs-related packages. 10# @ECLASS: elisp.eclass
11# @MAINTAINER:
12# Feel free to contact the Emacs team through <emacs@gentoo.org> if you
13# have problems, suggestions or questions.
14# @BLURB: Eclass for Emacs Lisp packages
15# @DESCRIPTION:
16#
17# This eclass is designed to install elisp files of Emacs related
18# packages into the site-lisp directory. The majority of elisp packages
19# will only need to define the standard ebuild variables (like SRC_URI)
20# and optionally SITEFILE for successful installation.
21#
22# Emacs support for other than pure elisp packages is handled by
23# elisp-common.eclass where you won't have a dependency on Emacs itself.
24# All elisp-* functions are documented there.
25#
26# If the package's source is a single (in whatever way) compressed elisp
27# file with the file name ${P}.el, then this eclass will move ${P}.el to
28# ${PN}.el in src_unpack().

10INHERITED="$INHERITED $ECLASS" 31# @DEFAULT_UNSET
32# @DESCRIPTION:
33# If you need anything different from Emacs 21, use the NEED_EMACS
34# variable before inheriting elisp.eclass. Set it to the major version
35# your package uses and the dependency will be adjusted.
