<h2>Nginx/Openresty appender</h2>
<p>This appender has no configuration options, and simply forwards whatever is
being logged to the configured Nginx log. LuaLogging log-levels will be converted
to the equivalent Nginx ones, and initial log-level will be set to match the
Nginx system level.</p>
<p>It makes sense to configure this logger and set it as the default logger on
Nginx/OpenResty startup. Any libraries will then be able to just grab the
defaultLogger from <code>logging.defaultLogger()</code> and won't need any
modifications to work with Nginx/OpenResty.</p>
<h2>Examples</h2>
<pre class="example">
require("logging.nginx")
local logging = require("logging")
local logger = logging.nginx()
logging.defaultLogger(logger)
logger:info("logging.nginx test")
logger:debug("debugging...")
logger:error("error!")
