51 #
52 # eautoreconf() - Should do a full autoreconf - normally what most people

55 # eaclocal() - Runs aclocal. Respects AT_M4DIR for additional directories
56 # to search for macro's.
57 # _elibtoolize() - Runs libtoolize. Note the '_' prefix .. to not collide
58 # with elibtoolize() from libtool.eclass
59 # eautoconf - Runs autoconf.
60 # eautoheader - Runs autoheader.
61 # eautomake - Runs automake
