34# the dependency should be on >=virtual/emacs-24 instead. Because the
35# user can select the Emacs executable with eselect, you should also
36# make sure that the active Emacs version is sufficient. This can be
37# tested with function elisp-need-emacs(), which would typically be

44# Please note that such tests should be limited to packages that are
