-`ikiwiki-update-wikilist` is designed to be made suid root, but not installed
-suid by default. If made suid, it allows users to add or remove their names
-from the `/etc/ikiwiki/wikilist` file. If a user's name is not in the file,
-it will be added; if the name is already present, it will be removed.
+`ikiwiki-update-wikilist` is designed to be safely run as root by arbitrary
+users, either by being made suid and using the (now deprecated suidperl), or
+by being configured in `/etc/sudoers` to allow arbitrary users to run.
+
+All it does is allows users to add or remove their names
+from the `/etc/ikiwiki/wikilist` file.
+
+By default, the user's name will be added.
+The `-r` switch causes the user's name to be removed.
