+<title>Sample Runtime Shell</title>
+</head>
+<body>
+<h1>It works</h1>
+
+<p>This Web app runs a sample Tuscany runtime shell similar to samples/launcher-shell.<br/>
+To see how it works and what configuration commands are supported, just read the Shell program's <a href="http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/running-tuscany/launcher-shell/src/main/java/sample/Shell.java">source code</a>.</p>
+
+<p>Configuration commands can be provided through a text document served from a Web location, for example:<br/>
+<a href="http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/running-tuscany/launcher-shell/scripts/test-start.txt">http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/running-tuscany/launcher-shell/scripts/test-start.txt</a></p>
+
+<p>To run that particular configuration script just point your Web browser to:<br/>
+<a href="/scashell/run?conf=http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/running-tuscany/launcher-shell/scripts/test-start.txt">http://localhost:8080/scashell/run?conf=http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/running-tuscany/launcher-shell/scripts/test-start.txt</a><br/>
+To run the script again and refresh the runtime shell, just refresh that page in your Web browser.
+</p>
+
+<p>This script starts the Tuscany sample store application. Click <a href="/scashell/store/">here</a> to use that application after you've started it.</p>
+
+<p>Sample configuration script samples are available in the Tuscany Subversion repository <a href="http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/running-tuscany/launcher-shell/scripts/">there</a>.
