# 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}.  The consequences:
#
# 1.) ${S} is redefined,
# 2.) ${PN}-${PV}.el is moved 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.
