27 # Functions:
28 #
29 # eautoreconf() - Should do a full autoreconf - normally what most people
30 # will be interested in. Also should handle additional
31 # directories specified by AC_CONFIG_SUBDIRS.
32 # eaclocal() - Runs aclocal. Respects AT_M4DIR for additional directories
33 # to search for macro's.
34 # _elibtoolize() - Runs libtoolize. Note the '_' prefix .. to not collide
35 # with elibtoolize() from libtool.eclass
36 # eautoconf - Runs autoconf.
37 # eautoheader - Runs autoheader.
38 # eautomake - Runs automake
