<h1>Expressions in rsyslog</h1>
<p>Rsyslog supports expressions at a growing number of places. So
far, they are supported for filtering messages.</p>
<p>Expression support is provided by RainerScript. Please see the
<a href="rainerscript.html">RainerScript documentation</a> for more details.</p>
<p>C-like comments (/* some comment */) are supported <b>inside</b> the expression,
but not yet in the rest of the configuration file.</p>
