10     # @DESCRIPTION:
11     # autotools-utils.eclass is autotools.eclass(5) and base.eclass(5) wrapper
12     # providing all inherited features along with econf arguments as Bash array,
13     # out of source build with overridable build dir location, static archives
14 mgorny 1.28 # handling, libtool files removal.
15     #
16     # Please note note that autotools-utils does not support mixing of its phase
17     # functions with regular econf/emake calls. If necessary, please call
18     # autotools-utils_src_compile instead of the latter.
