5# The autotools eclass enables building of the apps that needs the latest autconf/automake.
6# 7#
7# NOTES: 8# This eclass is for handling autotooled software packages that
9# needs to regenerate their build scripts.
8# 10#
9# This eclass was made to bridge the incompadibility problem of autoconf-2.13, 11# NB: If you add anything, please comment it!
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:
18#
19# The following is a commented template for how to use this eclass:
