+# @BLURB: cmake-utils wrapper for multilib builds
+# @DESCRIPTION:
+# The cmake-multilib.eclass is a cmake-utils.eclass(5) wrapper
+# introducing support for building for more than one ABI (multilib).
+#
+# Inheriting this eclass sets IUSE and exports cmake-utils phase
+# function wrappers which build the package for each supported ABI
+# if the appropriate flag is enabled.
+#
+# Note that the multilib support requires out-of-source builds to be
+# enabled. Thus, it is impossible to use CMAKE_IN_SOURCE_BUILD with
+# it.
+
+# EAPI=5 is required for meaningful MULTILIB_USEDEP.

+	5) ;;
+	*) die "EAPI=${EAPI} is not supported" ;;

+	die "${ECLASS}: multilib support requires out-of-source builds."
