You may give one or more space-separated answers, or "none" if appropriate.
-A well-behaved OS will have no hints, so answering "none" or just "Policy"
-is a good thing. DO NOT give a wrong version or a wrong OS.
+If you have a handcrafted Policy.sh file or a Policy.sh file generated by a
+previous run of Configure, you may specify it as well as or instead of
+OS-specific hints. If hints are provided for your OS, you should use them:
+although Perl can probably be built without hints on many platforms, using
+hints often improve performance and may enable features that Configure can't
+set up on its own. If there are no hints that match your OS, specify "none";
+DO NOT give a wrong version or a wrong OS.
