27# Functions:
28#
29# eautoreconf() - Should do a full autoreconf - normally what most people
30# will be interested in. Also should handle additional

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
