   METHODS
       CSAF::Writer inherits all methods from CSAF::Base and implements the following new ones.

       $writer->write ( $directory_path )
           Write the CSAF document in the specified $directory and create this structure:

                [ ROOT ]
                   |
                   |--> [ YEAR ]
                   |       |--> CSAF document (.json)
                   |       |--> SHA256 integrity file (.sha256)
                   |       |--> SHA512 integrity file (.sha512)
                   |       \--> GPG signature file (.asc)
                   |
                   |--> Index file (index.txt)
                   \--> Changes file (changes.csv)

           This  directory  structure is "ready" to be published through in webserver (Apache, NGINX and others)
           via "HTTPS".

               $writer->write('/var/www/html/advisories/csaf');

       $writer->options
           Change the default options for CSAF::Options::Writer configurator.

               $writer->options->configure(
                   create_sha256_integrity => 0,
                   create_gpg_signature    => 1,
                   update_index            => 1,
                   update_changes          => 1
               );

               if (my $passphrase = get_passphrase_from_stdin) {
                   $writer->options->gpg_passphrase($passphrase);
               }
