     * Generate all of the sitemap files needed to list the URLs from this
85 87
     * instance of Metacat, using the open sitemap format described here:
86
     * 
88
     *   http://www.sitemaps.org/protocol.html
87 89
     * URLs are written to a single file, unless the maximum number of URLs
88
     * allowed inthe sitemap file is exceeded, in which subsequent numbered
89
     * files are created.
90
     * allowed in the sitemap file is exceeded, in which subsequent numbered
91
     * files are created. An index of the sitemaps is also created.
90 92
     * 
93
     * The sitemap index can be registered with search index providers such as
94
     * Google, but beware that it needs to be accessible in a location above the
95
     * mount point for the service URLs.  By default the files are placed in 
96
     * {context}/sitemaps, but you will need to expose them at {context}/ for
97
     * them to be trusted by Google.  See the Sitemaps.org documentation for
98
     * details.
