 #
-# If you run 'ninja gn_build gyp_remaining gyp_groups', and then
-# run 'ninja', the second ninja invocation should do nothing. This
-# indicates that everything built by a ninja build is in fact
-# listed in one of these targets.
+# 'both_gn_and_gyp' lists what GN is currently capable of building and should
+# match the 'both_gn_and_gyp' target in //BUILD.gn.
 #
-# 'gn_all' lists what GN is currently capable of building and should
-#          match the 'gn_all' target in //BUILD.gn.
+# 'gyp_all' Should include everything built when building "all"; i.e., if you
+# type 'ninja gyp_all' and then 'ninja all', the second build should do
+# nothing. 'gyp_all' should just depend on the other four targets.
+#
+# 'gyp_only' lists any targets that are not meant to be ported over to the GN
+# build.
 #
 # 'gyp_remaining' lists all of the targets that still need to be converted,
-#          i.e., all of the other (non-empty) targets that a GYP build
-#          will build.
+# i.e., all of the other (non-empty) targets that a GYP build will build.
 #
-# 'gyp_groups' lists any empty (group) targets in the GYP build that
-#          are not picked up by gn_all or gyp_remaining; this is a
-#          separate target to ensure that when we build it, only
-#          stamp targets file are we don't accidentally pick up something
-#          not listed in one of the other two targets.
