111# @FUNCTION: eautoreconf
112# @DESCRIPTION:
113# This function mimes the behavior of autoreconf, but uses the different
114# eauto* functions to run the tools. It doesn't accept parameters, but
115# the directory with include files can be specified with AT_M4DIR variable.
6# 116#
7# NOTES: 117# Should do a full autoreconf - normally what most people will be interested in.
8# 118# Also should handle additional directories specified by AC_CONFIG_SUBDIRS.
9# This eclass was made to bridge the incompadibility problem of autoconf-2.13, 119eautoreconf() {
10# autoconf-2.5x and automake-1.4x, automake-1.5x. Most packages needs 120 local x auxdir g
11# autoconf-2.13 and automake-1.4x, but cannot work with the latest versions
12# of these packages due to incompadibility, thus when we have a package that
13# needs the latest versions of automake and autoconf, it begins to get a
14# problem.
