<title>JScript Debugger</title>
</head>
<body>
<p>
This is the debugger of JScript. It implement the <a href="https://chromedevtools.github.io/devtools-protocol/1-2/">V8 Debugging protocol</a>,
so you can use the devtools in chrome. <br>
The debugger is still in early development, so please report any issues to
<a href="https://github.com/TopchetoEU/java-jscript/issues">the github repo</a>.
</p>
<p>
Here are the available entrypoints:
<ul>
<li><a href="json/version">/json/version</a> - version and other stuff about the JScript engine</li>
<li><a href="json/list">/json/list</a> - a list of all entrypoints</li>
<li><a href="json/protocol">/json/protocol</a> - documentation of the implemented V8 protocol</li>
<li>/(any target) - websocket entrypoints for debugging</li>
</ul>

Running ${NAME} v${VERSION} by ${AUTHOR}
