The arg must be formatted as I</type0=value0/type1=value1/type2=...>,
characters may be escaped by \ (backslash), no spaces are skipped.
+=item B<-multivalue-rdn>
+
+this option causes the -subj argument to be interpreted with full
+support for multivalued RDNs. Example:
+
+I</DC=org/DC=OpenSSL/DC=users/UID=123456+CN=John Doe>
+
+If -multi-rdn is not used then the UID value is I<123456+CN=John Doe>.
+
=item B<-x509>
this option outputs a self signed certificate instead of a certificate
print extra details about the operations being performed.
+=item B<-engine id>
+
+specifying an engine (by it's unique B<id> string) will cause B<req>
+to attempt to obtain a functional reference to the specified engine,
+thus initialising it if needed. The engine will then be set as the default
+for all available algorithms.
