26 #
27 # eautoreconf() - Should do a full autoreconf - normally what most people

30 # eaclocal() - Runs aclocal. Respects AT_M4DIR for additional directories
31 # to search for macro's.
32 # _elibtoolize() - Runs libtoolize. Note the '_' prefix .. to not collide
33 # with elibtoolize() from libtool.eclass
34 # eautoconf - Runs autoconf.
35 # eautoheader - Runs autoheader.
36 # eautomake - Runs automake
