       This command takes a file containing a Netscape certificate sequence and prints out the certificates
       contained in it or takes a file of certificates and converts it into a Netscape certificate sequence.

       A Netscape certificate sequence is an old Netscape-specific format that can be sometimes be sent to
       browsers as an alternative to the standard PKCS#7 format when several certificates are sent to the
       browser, for example during certificate enrollment.  It was also used by Netscape certificate server.

       Output the certificates in a Netscape certificate sequence

        openssl nseq -in nseq.pem -out certs.pem

       Create a Netscape certificate sequence

        openssl nseq -in certs.pem -toseq -out nseq.pem

-help
           Print out a usage message.

       -infilename
           This specifies the input filename to read or standard input if this option is not specified.

       -outfilename
           Specifies the output filename or standard output by default.

       -toseq
           Normally  a  Netscape certificate sequence will be input and the output is the certificates contained
           in it. With the -toseq option the situation is reversed: a Netscape certificate sequence  is  created
           from a file of certificates.
