13# @BLURB: Eclass for Emacs Lisp packages
14# @DESCRIPTION:
15#
16# This eclass sets the site-lisp directory for Emacs-related packages.
17#
18# Emacs support for other than pure elisp packages is handled by
19# elisp-common.eclass where you won't have a dependency on Emacs itself.
20# All elisp-* functions are documented there.
21#
22# Setting SIMPLE_ELISP=t in an ebuild means, that the package's source
23# is a single (in whatever way) compressed elisp file with the file name
24# ${PN}-${PV}. This eclass will then redefine ${S}, and move
25# ${PN}-${PV}.el to ${PN}.el in src_unpack().
26#
27# DOCS="blah.txt ChangeLog" is automatically used to install the given
28# files by dodoc in src_install().
29#
30# If you need anything different from Emacs 21, use the NEED_EMACS
31# variable before inheriting elisp.eclass. Set it to the major version
32# your package uses and the dependency will be adjusted.
