+       Work similar to the <command>update</command> command above, but get the
+       archive keyring from an URI instead and validate it against a master key.
+
+       This requires an installed &wget; and an APT build configured to have
+       a server to fetch from and a master keyring to validate.
+
+       APT in Debian does not support this command and relies on
+       <command>update</command> instead, but Ubuntu's APT does.
