41 # eautoreconf call.

43 # useful when elibtoolize needs to be ran with
44 # particular options
45
46 # Functions:
47 #
48 # eautoreconf() - Should do a full autoreconf - normally what most people
49 # will be interested in. Also should handle additional
50 # directories specified by AC_CONFIG_SUBDIRS.
51 # eaclocal() - Runs aclocal. Respects AT_M4DIR for additional directories
52 # to search for macro's.
53 # _elibtoolize() - Runs libtoolize. Note the '_' prefix .. to not collide
54 # with elibtoolize() from libtool.eclass
55 # eautoconf - Runs autoconf.
56 # eautoheader - Runs autoheader.
57 # eautomake - Runs automake
