16# This eclass sets the site-lisp directory for Emacs-related packages. 17# This eclass is designed to install elisp files of Emacs related
18# packages into the site-lisp directory. The majority of elisp packages
19# will only need to define the standard ebuild variables (like SRC_URI)
20# and optionally SITEFILE for successful installation.
