35 # eaclocal() - Runs aclocal. Respects AT_M4DIR for additional directories
36 # to search for macro's.
37 # _elibtoolize() - Runs libtoolize. Note the '_' prefix .. to not collide
38 # with elibtoolize() from libtool.eclass
39 # eautoconf - Runs autoconf.
40 # eautoheader - Runs autoheader.
41 # eautomake - Runs automake
