+# @BLURB: autotools-utils wrapper for multilib builds
+# @DESCRIPTION:
+# The autotools-multilib.eclass is an autotools-utils.eclass(5) wrapper
+# introducing support for building for more than one ABI (multilib).
+#
+# Inheriting this eclass sets the USE flags and exports autotools-utils
+# phase function wrappers which build the package for each supported ABI
+# when the relevant flag is enabled. Other than that, it works like
+# regular autotools-utils.
+#
+# Note that the multilib support requires out-of-source builds to be
+# enabled. Thus, it is impossible to use AUTOTOOLS_IN_SOURCE_BUILD with
+# it.
+
+# EAPI=4 is required for meaningful MULTILIB_USEDEP.
