-# Generate dark greylist as remaining members of classes on the light greylist,

+# Generate dark greylist as remaining classes and class members in the same
+# package as classes listed in the light greylist.
 # The algorithm is as follows:
 #   (1) extract the class descriptor from each entry in LOCAL_LIGHT_GREYLIST
-#   (2) strip the final semicolon and anything after (and including) a dollar sign,
-#       e.g. 'Lpackage/class$inner;' turns into 'Lpackage/class'
-#   (3) insert all entries from LOCAL_SRC_PRIVATE_API which begin with the stripped
-#       descriptor followed by a semi-colon or a dollar sign, e.g. matching a regex
-#       '^Lpackage/class[;$]'
+#   (2) strip everything after the last forward-slash,
+#       e.g. 'Lpackage/subpackage/class$inner;' turns into 'Lpackage/subpackage/'
+#   (3) insert all entries from LOCAL_SRC_PRIVATE_API which begin with the package
+#       name but do not contain another forward-slash in the class name, e.g.
+#       matching '^Lpackage/subpackage/[^/;]*;'
 #   (4) subtract entries shared with LOCAL_LIGHT_GREYLIST
