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.

56 # If multilib support is disabled, it just runs the commands. No setup
