/**
* This class lets you export a static copy of your site.
* It creates a huge number of folders each containing an index.html file.
* This preserves the URL naming format.
*
* Requirements: Unix Filesystem supporting symlinking. Doesn't work on Windows.
*
* <b>Usage</b>
*
* The exporter can only be invoked through a URL. Usage on commandline (through [sake](sake)) is not possible at the moment, as we're sending a file to the browser for download.
*
* <pre>http://localhost/StaticExporter/export</pre>
*
* Specify a custom baseurl in case you want to deploy the static HTML pages on a different host:
* <pre>http://localhost/StaticExporter/export?baseurl=http://example.com</pre>
*
* @see StaticPublisher
*
* @package cms
* @subpackage export
