+|
+| Enables output compression using Gzip for faster page loads. When enabled,
+| the output class will test whether the server your site is running on
+| supports Gzip. Even if it does, however, not all browsers support compression
+| so enable only if you are reasonably sure your visitors can handle it.
+|
+| VERY IMPORTANT: If you are getting a blank page when this is enabled it
+| means you are prematurely outputing something to your browser. It could
+| even be a line of whitespace at the end of one of your scripts. For
+| compression to work, nothing can be sent before the output buffer is called
+| by the output class.
