 #
 # We are moving wtf/ files to platform/wtf/ incrementally, thus, conceptually,
 # the "wtf" target in wtf/BUILD.gn is being split into two, in a way that
 # only wtf/ can refer the contents in platform/wtf/.
 #
 # To achieve this, we introduce a new target "platform_wtf" here, and configure
 # it so the source files are compiled in the same way as the original "wtf"
 # target. This gn file should only be used from wtf/BUILD.gn, and this
 # restriction is enforced by the visibility rule below (but it's okay to
 # #include a header in this directory from core/ or modules/).
 #
 # The following configurations are mostly copied from wtf/BUILD.gn, so we
 # can build the source files in the same way.
 #
 # When we finish moving all the files, "platform_wtf" target will take over
 # the role of "wtf".
+#
+# TODO(yutak): Set up platform_wtf_unittests in the similar manner.
