+** Security Note:
+** If you have restricted chown (that is, you can't
+** give a file away), it is reasonable to allow programs
+** and files called from this :include: file to be to be
+** run as the owner of the :include: file. This is bogus
+** if there is any chance of someone giving away a file.
+** We assume that pre-POSIX systems can give away files.
+**
+** There is an additional restriction that if you
+** forward to a :include: file, it will not take on
+** the ownership of the :include: file. This may not
+** be necessary, but shouldn't hurt.
