10# This eclass sets the site-lisp directory for emacs-related packages.
11#
12# Emacs support for other than pure elisp packages is handled by
13# elisp-common.eclass where you won't have a dependency on Emacs itself.
14# All elisp-* functions are documented there.
15#
16# Setting SIMPLE_ELISP=t in an ebuild means, that the package's source
17# is a single (in whatever way) compressed elisp file with the file name
18# ${PN}-${PV}. The consequences:
19#
20# 1.) ${S} is redefined,
21# 2.) ${PN}-${PV}.el is moved to ${PN}.el in src_unpack().
22#
23# DOCS="blah.txt ChangeLog" is automatically used to install the given
24# files by dodoc in src_install().
25#
26# If you need anything different from Emacs 21, use the NEED_EMACS
27# variable before inheriting elisp.eclass. Set it to the major version
28# your package uses and the dependency will be adjusted.
