+=head1 NAME
+
+openssl-nseq - create or examine a Netscape certificate sequence
+
+=head1 SYNOPSIS
+
+B<openssl> B<nseq>
+[B<-help>]
+[B<-in> I<filename>]
+[B<-out> I<filename>]
+[B<-toseq>]
+
+=head1 DESCRIPTION
+
+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.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-help>
+
+Print out a usage message.
+
+=item B<-in> I<filename>
+
+This specifies the input filename to read or standard input if this
+option is not specified.
+
+=item B<-out> I<filename>
+
+Specifies the output filename or standard output by default.
+
+=item B<-toseq>
+
+Normally a Netscape certificate sequence will be input and the output
+is the certificates contained in it. With the B<-toseq> option the
+situation is reversed: a Netscape certificate sequence is created from
+a file of certificates.
