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

8# 7#
9# This eclass was made to bridge the incompadibility problem of autoconf-2.13, 8# This eclass is for handling autotooled software packages that
10# autoconf-2.5x and automake-1.4x, automake-1.5x. Most packages needs 9# needs to regenerate their build scripts.
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# 10#
