# @ECLASS: elisp.eclass
# @MAINTAINER:
# emacs@gentoo.org
# @BLURB: Eclass for Emacs Lisp packages
# @DESCRIPTION:
#
# This eclass sets the site-lisp directory for Emacs-related packages.
#
# Emacs support for other than pure elisp packages is handled by
# elisp-common.eclass where you won't have a dependency on Emacs itself.
# All elisp-* functions are documented there.
#
# Setting SIMPLE_ELISP=t in an ebuild means, that the package's source
# is a single (in whatever way) compressed elisp file with the file name
# ${PN}-${PV}. This eclass will then redefine ${S}, and move
# ${PN}-${PV}.el to ${PN}.el in src_unpack().
#
# DOCS="blah.txt ChangeLog" is automatically used to install the given
# files by dodoc in src_install().
#
# If you need anything different from Emacs 21, use the NEED_EMACS
# variable before inheriting elisp.eclass. Set it to the major version
# your package uses and the dependency will be adjusted.
