+# Default value is "no". If set to "yes", add an unconditional dependency on
+# trinity-base/arts and trinity-base/tdelibs[arts], if "optional" add both
+# dependencies with IUSE="arts".
+# TODO: This variable was set by the need-arts function but all invocations of
+# need-arts should be replaced by setting TRINITY_NEED_ARTS directly in ebuild
+# before inheriting this eclass.
