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.
10# 21#
11# Emacs support for other than pure elisp packages is handled by 22# Emacs support for other than pure elisp packages is handled by
12# elisp-common.eclass where you won't have a dependency on Emacs 23# elisp-common.eclass where you won't have a dependency on Emacs itself.
13# itself. All elisp-* functions are documented there. 24# All elisp-* functions are documented there.
14# 25#
15# Setting SIMPLE_ELISP=t in an ebuild means, that the package's source 26# If the package's source is a single (in whatever way) compressed elisp
16# is a single (in whatever way) compressed elisp file with the file name 27# file with the file name ${P}.el, then this eclass will move ${P}.el to
17# ${PN}-${PV}. The consequences: 28# ${PN}.el in src_unpack().
18#
19# 1.) ${S} is redefined
20# 2.) ${PN}-${PV}.el is moved to ${PN} in the system.

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