48 # AM_OPTS - Additional options to pass to automake during
49 # eautoreconf call.

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