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.
11# 21#
12# Emacs support for other than pure elisp packages is handled by 22# Emacs support for other than pure elisp packages is handled by
13# 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.
14# itself. All elisp-* functions are documented there. 24# All elisp-* functions are documented there.
15# 25#
16# 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
17# 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
18# ${PN}-${PV}. The consequences: 28# ${PN}.el in src_unpack().
19# 29
20# 1.) ${S} is redefined 30# @ECLASS-VARIABLE: NEED_EMACS
21# 2.) ${PN}-${PV}.el is moved to ${PN} in the system. 31# @DESCRIPTION:
22#
23# SRC_URI should be set to wherever the primary app-emacs/ maintainer
24# keeps the local elisp mirror, since most app-emacs packages are
25# upstream as a single .el file.
26#
27# DOCS="blah.txt ChangeLog" is automatically used to install the given
28# files by dodoc in src_install().
