74# @FUNCTION: eautoreconf
75# @DESCRIPTION:
76# This function mimes the behavior of autoreconf, but uses the different
77# eauto* functions to run the tools. It doesn't accept parameters, but
78# the directory with include files can be specified with AT_M4DIR variable.
8# 79#
9# This eclass was made to bridge the incompadibility problem of autoconf-2.13, 80# Should do a full autoreconf - normally what most people will be interested in.
10# autoconf-2.5x and automake-1.4x, automake-1.5x. Most packages needs 81# Also should handle additional directories specified by AC_CONFIG_SUBDIRS.
11# autoconf-2.13 and automake-1.4x, but cannot work with the latest versions 82eautoreconf() {
12# of these packages due to incompadibility, thus when we have a package that 83 local x auxdir g
13# needs the latest versions of automake and autoconf, it begins to get a
14# problem.
