21 # Variables:
22 #
23 # AT_M4DIR - Additional director(y|ies) aclocal should search
24 # AT_GNUCONF_UPDATE - Should gnuconfig_update() be run (normally handled by
25 # econf()) [yes|no]
26 # AM_OPTS - Additional options to pass to automake during
27 # eautoreconf call.
28
29 # Functions:
30 #
31 # eautoreconf() - Should do a full autoreconf - normally what most people
32 # will be interested in. Also should handle additional
33 # directories specified by AC_CONFIG_SUBDIRS.
34 # eaclocal() - Runs aclocal. Respects AT_M4DIR for additional directories
35 # to search for macro's.
36 # _elibtoolize() - Runs libtoolize. Note the '_' prefix .. to not collide
37 # with elibtoolize() from libtool.eclass
38 # eautoconf - Runs autoconf.
39 # eautoheader - Runs autoheader.
40 # eautomake - Runs automake
