+<h3 id="shutdown-hook">Shutdown Hook</h3>
+<p>By default the Sling Launchpad standalone application installs a Shutdown Hook with
the Java Runtime to make sure the framework is properly
+terminated in case of a Java termination. In some situations or setups you want to control
shutdown of Sling yourselves, so Sling supports a command
+line option <code>-n</code> to prevent the installation of a shutdown hook.</p>

system property is also supported: If this property is set to <code>true</code>
or is not set at all

 <h2 id="servlet-parameters">Servlet Parameters</h2>
 <p>The Web Application does not require specific servlet parameters. Those which are
specified are used to overwrite any properties with the same name from the <code></code>
file. One exception to this rule is the <code>sling.home</code> parameter, which
is used to set the value of the <code>sling.home</code> property. If no parameter
with this name is defined the Sling home directory is derived from the context path at which
the Sling Web Application is registered.</p>
 <p>The <code>sling.home</code> folders for Sling Web Applications without
the <code>sling.home</code> servlet parameter are all located in the <code>sling</code>
folder in the current working directory as reported by the <code>user.dir</code>
system property. The name of the actual directory is derived from the Web Application Context
Path by replacing all slash characters <code>/</code> by underscore characters
<code>_</code>. For the root context a single underscore character <code>_</code>
is used.</p>
