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# ${PN}.el in src_unpack().
5 26
6# This eclass sets the site-lisp directory for emacs-related packages. 27# @ECLASS-VARIABLE: DOCS
28# @DESCRIPTION:
29# DOCS="blah.txt ChangeLog" is automatically used to install the given
30# files by dodoc in src_install().
7 31
8ECLASS=elisp 32# @ECLASS-VARIABLE: NEED_EMACS
9INHERITED="$INHERITED $ECLASS" 33# @DESCRIPTION:
34# If you need anything different from Emacs 21, use the NEED_EMACS
35# variable before inheriting elisp.eclass. Set it to the major version
36# your package uses and the dependency will be adjusted.
