13# @BLURB: Eclass for Emacs Lisp packages
14# @DESCRIPTION:
9# 15#
10# This eclass sets the site-lisp directory for emacs-related packages. 16# This eclass is designed to install elisp files of Emacs related
17# packages into the site-lisp directory. The majority of elisp packages
18# will only need to define the standard ebuild variables (like SRC_URI)
19# and optionally SITEFILE for successful installation.
11# 20#
12# Emacs support for other than pure elisp packages is handled by 21# Emacs support for other than pure elisp packages is handled by
13# elisp-common.eclass where you won't have a dependency on Emacs itself. 22# elisp-common.eclass where you won't have a dependency on Emacs itself.
14# All elisp-* functions are documented there. 23# All elisp-* functions are documented there.

16# Setting SIMPLE_ELISP=t in an ebuild means, that the package's source 25# If the package's source is a single (in whatever way) compressed elisp
17# is a single (in whatever way) compressed elisp file with the file name 26# file with the file name ${P}.el, then this eclass will move ${P}.el to
18# ${PN}-${PV}. The consequences: 27# ${PN}.el in src_unpack().
