Print out a usage message.
-=item B<-inform DER|PEM>
+=item B<-inform> B<DER>|B<PEM>
This specifies the CRL 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 default format is PEM.
-=item B<-outform DER|PEM>
+=item B<-outform> B<DER>|B<PEM>
This specifies the PKCS#7 structure output format. B<DER> format is DER
encoded PKCS#7 structure.B<PEM> (the default) is a base64 encoded version of
the DER form with header and footer lines. The default format is PEM.
-=item B<-in filename>
+=item B<-in> I<filename>
This specifies the input filename to read a CRL from or standard input if this
option is not specified.
-=item B<-out filename>
+=item B<-out> I<filename>
Specifies the output filename to write the PKCS#7 structure to or standard
output by default.
-=item B<-certfile filename>
+=item B<-certfile> I<filename>
Specifies a filename containing one or more certificates in B<PEM> format.
All certificates in the file will be added to the PKCS#7 structure. This
