- * Content-Encoding and Content-Length are added.

- * // Send a CSS file, compressed if possible
- * $he = new HTTP_Encoder(array(
- *     'content' => file_get_contents($cssFile)
- *     ,'type' => 'text/css'

- * // Shortcut to encoding output

- * HTTP_Encoder::output($css);
- * </code>
- * 
- * <code>
- * // Just sniff for the accepted encoding
- * $encoding = HTTP_Encoder::getAcceptedEncoding();
- * </code>
- *
- * For more control over headers, use getHeaders() and getData() and send your
- * own output.
- * 
- * Note: If you don't need header mgmt, use PHP's native gzencode, gzdeflate, 
- * and gzcompress functions for gzip, deflate, and compress-encoding
- * respectively.
