Yes, I want to provide feature "tema" and subfeatures "lumi" and "mast".
I want to know the way to include the subfeatures in "lumi" and "mast".
in "tema.el".  Does one use the "include" clause, and how should it look
like?

Currently I have

;; code of tema.el
(provide 'tema '(lumi mast))

;; code of lumi.el
(provide 'tema '(lumi))

;; code of mast.el
(provide 'tema '(mast))
