 print extra information about the operations being performed.
 
 =item B<-issuer_checks>
 
 print out diagnostics relating to searches for the issuer certificate
 of the current certificate. This shows why each candidate issuer
 certificate was rejected. However the presence of rejection messages
 does not itself imply that anything is wrong: during the normal
 verify process several rejections may take place.
 
+=item B<-policy arg>
+
+Enable policy processing and add B<arg> to the user-initial-policy-set
+(see RFC3280 et al). The policy B<arg> can be an object name an OID in numeric
+form. This argument can appear more than once.
+
+=item B<-policy_check>
+
+Enables certificate policy processing.
+
+=item B<-explicit_policy>
+
+Set policy variable require-explicit-policy (see RFC3280 et al).
+
+=item B<-inhibit_any>
+
+Set policy variable inhibit-any-policy (see RFC3280 et al).
+
+=item B<-inhibit_map>
+
+Set policy variable inhibit-policy-mapping (see RFC3280 et al).
+
+=item B<-policy_print>
+
+Print out diagnostics, related to policy checking
+
+=item B<-crl_check>
+
+Checks end entity certificate validity by attempting to lookup a valid CRL.
+If a valid CRL cannot be found an error occurs. 
+
+=item B<-crl_check_all>
+
+Checks the validity of B<all> certificates in the chain by attempting
+to lookup valid CRLs.
+
+=item B<-ignore_critical>
+
+Normally if an unhandled critical extension is present which is not
+supported by OpenSSL the certificate is rejected (as required by
+RFC3280 et al). If this option is set critical extensions are
+ignored.
+
+=item B<-x509_strict>
+
+Disable workarounds for broken certificates which have to be disabled
+for strict X.509 compliance.
+
+=item B<-extended_crl>
+
+Enable extended CRL features such as indirect CRLs and alternate CRL
+signing keys.
+
+=item B<-use_deltas>
+
+Enable support for delta CRLs.
+
 =item B<-check_ss_sig>
 
 Verify the signature on the self-signed root CA. This is disabled by default
 because it doesn't add any security.
 
 =item B<->
 
 marks the last option. All arguments following this are assumed to be
 certificate files. This is useful if the first certificate filename begins
 with a B<->.
