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 sets the site-lisp directory for Emacs-related packages.
18#
19# Emacs support for other than pure elisp packages is handled by
20# elisp-common.eclass where you won't have a dependency on Emacs itself.
21# All elisp-* functions are documented there.
22#
23# If the package's source is a single (in whatever way) compressed elisp
24# file with the file name ${P}.el, then this eclass will move ${P}.el to
25# ${PN}.el in src_unpack().
5 26
6# This eclass sets the site-lisp directory for emacs-related packages. 27# @ECLASS-VARIABLE: SITEFILE
28# @DESCRIPTION:
29# Name of package's site-init file. The filename must match the shell
30# pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are
31# reserved for internal use. "50${PN}-gentoo.el" is a reasonable choice
32# in most cases.
7 33
8ECLASS=elisp 34# @ECLASS-VARIABLE: DOCS
9INHERITED="$INHERITED $ECLASS" 35# @DESCRIPTION:
36# DOCS="blah.txt ChangeLog" is automatically used to install the given
37# files by dodoc in src_install().
10 38
11SITELISP=/usr/share/emacs/site-lisp 39# @ECLASS-VARIABLE: NEED_EMACS
40# @DESCRIPTION:
41# If you need anything different from Emacs 21, use the NEED_EMACS
42# variable before inheriting elisp.eclass. Set it to the major version
43# your package uses and the dependency will be adjusted.
