+Reads a specification from stdin or a file and outputs a PKCS12
+file with the desired properties.
+
+The input format currently consists of a pycert certificate
+specification (see pycert.py).
+Currently, keys other than the default key are not supported.
+The password that is used to encrypt and authenticate the file
+is "password".
