8     # @BLURB: autotools-utils wrapper for multilib builds
9     # @DESCRIPTION:
10     # The autotools-multilib.eclass is an autotools-utils.eclass(5) wrapper
11     # introducing support for building for more than one ABI (multilib).
12     #
13     # Inheriting this eclass sets IUSE=multilib and exports autotools-utils
14     # phase function wrappers which build the package for each supported ABI
15     # if the flag is enabled. Otherwise, it works like regular
16     # autotools-utils.
17     #
18     # Note that the multilib support requires out-of-source builds to be
19     # enabled. Thus, it is impossible to use AUTOTOOLS_IN_SOURCE_BUILD with
20     # it.
