-This specifies the input format. B<DER> format is DER encoded CRL
-structure. B<PEM> (the default) is a base64 encoded version of
-the DER form with header and footer lines.
+The input and output formats of the CRL; the default is B<PEM>.
+See L<openssl(1)/Format Options> for details.

+=item B<-keyform> B<DER>|B<PEM>|B<ENGINE>
-This specifies the output format, the options have the same meaning and default
-as the B<-inform> option.
+The format of the private key file; the default is B<PEM>.
+See L<openssl(1)/Format Options> for details.

Output the nextUpdate field.

-Verify the signature on a CRL by looking up the issuing certificate in
-I<file>.
-
-=item B<-CApath> I<dir>
-
-Verify the signature on a CRL by looking up the issuing certificate in
-I<dir>. This directory must be a standard certificate directory: that
-is a hash of each subject name (using the L<openssl-x509(1)> B<-hash> option)
-should be linked to each certificate.
+See L<openssl(1)/Trusted Certificate Options> for more information.

-
-The PEM CRL format uses the header and footer lines:
-
- -----BEGIN X509 CRL-----
- -----END X509 CRL-----
