+	* Add options --is-encrypted and --requires-password. These can be
+	used with files, including encrypted files with unknown passwords,
+	to determine whether or not a file is encrypted and whether a

+	is correct. Information is supplied through exit codes, making
+	these options particularly useful for shell scripts. Fixes #390.
