17=head1 DESCRIPTION
18
19This command takes a file containing a Netscape certificate
20sequence and prints out the certificates contained in it or takes a
21file of certificates and converts it into a Netscape certificate
22sequence.
23
24A Netscape certificate sequence is an old Netscape-specific format that
25can be sometimes be sent to browsers as an alternative to the standard PKCS#7
26format when several certificates are sent to the browser, for example during
27certificate enrollment.  It was also used by Netscape certificate server.

30
31=over 4
32
33=item B<-help>
34
35Print out a usage message.
36
37=item B<-in> I<filename>
38
39This specifies the input filename to read or standard input if this
40option is not specified.
41
42=item B<-out> I<filename>
43
44Specifies the output filename or standard output by default.
45
46=item B<-toseq>
47
48Normally a Netscape certificate sequence will be input and the output
49is the certificates contained in it. With the B<-toseq> option the
50situation is reversed: a Netscape certificate sequence is created from
51a file of certificates.
