5# The autotools eclass enables building of the apps that needs the latest autconf/automake. 4

8# @BLURB: Regenerates auto* build scripts
9# @DESCRIPTION:
10# This eclass is for safely handling autotooled software packages that need to
11# regenerate their build scripts. All functions will abort in case of errors.
6# 12#
7# NOTES: 13# NB: If you add anything, please comment it!
8#
9# This eclass was made to bridge the incompadibility problem of autoconf-2.13,
10# autoconf-2.5x and automake-1.4x, automake-1.5x. Most packages needs
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.
15#
16#
17# Commented Example:

19# The following is a commented template for how to use this eclass:
