47 # Functions:
48 #
49 # eautoreconf() - Should do a full autoreconf - normally what most people
50 # will be interested in. Also should handle additional
51 # directories specified by AC_CONFIG_SUBDIRS.
52 # eaclocal() - Runs aclocal. Respects AT_M4DIR for additional directories
53 # to search for macro's.
54 # _elibtoolize() - Runs libtoolize. Note the '_' prefix .. to not collide
55 # with elibtoolize() from libtool.eclass
56 # eautoconf - Runs autoconf.
57 # eautoheader - Runs autoheader.
58 # eautomake - Runs automake
