+# This eclass contains the default phase functions for packages which
+# use the meson build system.
+#
+# @EXAMPLE:
+# Typical ebuild using meson.eclass:
+#
+# @CODE
+# EAPI=6
+#
+# inherit meson
+#
+# ...
+#
+# src_configure() {
+# local emesonargs=(
+# -Dqt4=$(usex qt4 true false)
+# -Dthreads=$(usex threads true false)
+# -Dtiff=$(usex tiff true false)
+# )
+# meson_src_configure
+# }
+#
+# ...
+#
+# @CODE
