+# @BLURB: meson wrapper for multilib builds
+# @DESCRIPTION:
+# The meson-multilib.eclass provides a glue between meson.eclass(5)
+# and multilib-minimal.eclass(5), aiming to provide a convenient way
+# to build packages using meson for multiple ABIs.
+#
+# Inheriting this eclass sets IUSE and exports default multilib_src_*()
+# sub-phases that call meson phase functions for each ABI enabled.
+# The multilib_src_*() functions can be defined in ebuild just like
+# in multilib-minimal, yet they ought to call appropriate meson
+# phase rather than 'default'.
