<div class="verseblock">
<pre class="content">        <em>TEP_LOG_NONE</em> - Do not print any logs.
        <em>TEP_LOG_CRITICAL</em> - Print critical logs, problem that may cause a crash.
        <em>TEP_LOG_ERROR</em> - Print error logs, problem that could break the main logic of an API.
        <em>TEP_LOG_WARNING</em> - Print warnings, problem that could limit the result of an API.
        <em>TEP_LOG_INFO</em> - Print information about normal execution of an API.
        <em>TEP_LOG_DEBUG</em> - Print debug information.
        <em>TEP_LOG_ALL</em> - Print logs from all levels.</pre>
<div class="attribution">
</div></div>
<div class="paragraph"><p>Setting the log level to specific value means that logs from the previous levels will be printed
too. For example <em>TEP_LOG_WARNING</em> will print any logs with severity <em>TEP_LOG_WARNING</em>,
<em>TEP_LOG_ERROR</em> and <em>TEP_LOG_CRITICAL</em>. The default log level is <em>TEP_LOG_CRITICAL</em>.</p></div>
